Happy New Year!

I'm now ready to play our Malkovich game as promised on my introduction thread. I guessed even so take black. Japanese rules, 6.5 komi, open book/database.

Have fun!

This game should be interesting. My impression is Magicwand likes influence and tends to overplay (particularly when giving handicap), whereas I tend to like territory and honte so we can both be happy :) . However, lately I've been trying out a more flexible style so let's see how this game develops.

As for my first move at 4-4, I still haven't decided if I like 4-4s or 3-4s better so I usually play one of each. Whether I go for a standard opening like Chinese/Kobayashi/Orthodox/Mini-Chinese depends what corners he plays, but based on his previous games I expect he will play 2 4-4s which gives me many choices.

We played a game on OGS, where Magicwand as black made a big moyo and I took territory. I then outplayed him in the fighting and he ended up losing pretty badly. In fact that game is why I joined L19 as I thought it would have made a good malkovich game. You can see the game and my review at http://www.online-go.com/games/board.php?boardID=305481. I wonder if that game will make him play more sensible moves, or will he do his usual style? I hope he does overplay as that should be fun for observers and if/when (hopefully the later!) I punish them I will be winning. I suppose I am black now and it is more natural for black to be the one to choose a moyo game though.

gg
i have seen his games and actually played one game and lost.
i think he is very careful on his move selection.
many times i dont agree with his comment.
sometimes he plays toomuch of point oriented game.
i think i am stronger and will win this game easily.

I really love Magicwand's confidence :) My impression is that Uberdude is at least slightly stronger in slow games, but I'm not a good judge since I've never won against either :p

In any case, this should be an exciting and didactic game :D

i should have home court advantage on this game.
i am so~~~ into this game..i been staring at this board position with two stone for last 10 min.
i expect nothing less than solid win.

i will overpower him by attacking his weakness of point oriented game.
once i obtain 5 points or more advantage.. i will try to win by not giving him any chance.

i think i will write what is in my mind and there might not be any diag about future expectation of board position.
this game i hope i can share my though process more than explaining my moves.
let me know if you have any question. little interaction with observer is like an oasis for the players who are blindfolded.

Also leaning towards Uberdude, but Magicwand doesn't seem as much in the overplay mentality as in other games. Should be interesting. :)

I'll throw my chips in with Magicwand.

While Uberdude does seem like the more studious player, Magicwand seems very motivated this game and I feel confident he will bring his full power to bear.


Good game guys.

I really want to see this game, since I'm also a very point-oriented player and I'd like to see how my judgment matches up to MW and Uberdude. I won't say who I think will win, because I've only ever played MW.

Man that is a GREAT GAME they played on ogs, i like the comments too.

I like Uberdude he comes across as a sharp tactican like Sakata Eio.

Magicwand is like a great kung fu master
he is a fighter mind body & soul and when he fights its looks like a form of art

I'm a magicwand fan, i like his comments & board vision and his fighting style so i say magicwand, he lost one game and he is back with the eye of the tiger!

where is my popcorn :D

Wow, look at all those hidden comments, I wonder what they say! :scratch:

I played at the London Open tournament last week (didn't do very well, played too slowly so kept throwing away games I was leading with mistakes in overtime) and was reviewing one of my games when a friend came over to watch and asked to see the start of the game. We rewound to the position with 4 corners played, but he said 'No, all the way back, the order of the corners is important' which might seem a bit picky but he does have a point. So as an homage to him, here's far too much discussion about corners.

Magicwand's move at d4 is diagonal from mine, so this stops me from playing a diagonal (tasuki) fuseki. There used to by a guy on KGS who had as his game note "no diagonal games" and then if you were black and played diagonal he would resign. Every so often the EGR would discuss his stupidity as he can just played white 2 diagonally to prevent it, but I prefer to think of him as a genius troll ;-).

If I play 4-4 as move 2 for white I will generally play it in the upper left. This is because if black then plays 3-4 in the lower right he could be aiming to set up a Chinese or Kobayashi or Mini-Chinese opening, which white might may wish to avoid (of course there's nothing wrong with letting your opponent make these formations, it's just a personal preference, for me it depends on my mood). One way to thwart black's plans to play these openings is then to not play a 4-4 in the lower left. I expect Magicwand will play 2 4-4s whatever black does so it's not relevant to him, but here is the thinking with diagrams:

White 4 doesn't actually stop black from making the Chinese opening (like an approach to :b3: would), but stops it indirectly by making it bad to make it. The theory is that with the shimari of :w6: white limits black's influence over the lower right corner of the board, and the moyo off the 3-4 is the focal point of the Chinese opening. So instead of :b5: at r9 black will probably approach white in the lower left and it's a different game. I got this idea from the excellent A Dictionary Of Modern Fuseki, The Korean Style.

This is the Kobayashi opening (there's a variant with 7 at a) and stopping it is as simple as playing :w4: at d3 because then black can't approach from the lower side. You can of course stop it even having played a 4-4 by pincering or approaching black's 3-4 in the lower right.

Stopping the mini-Chinese is the same idea as the Kobayashi, don't play a 4-4 to avoid giving the f3 approach, or pincer or counter-approach when approached. The classical theory is it's better to play the d3 3-4 point than the c4 one as the later means there are facing 3-4 points, and then whoever has sente (black) to approach gets a nice position.

So by playing his 4-4 in the lower left for move 2 Magicwand can't move it to the 3-4 to prevent me threatening to make these common opening shapes. Anyway, for this game I think I will go for a modern variant of the Chinese, of which more later if Magicwand plays d16 as I expect.

He played d16 as expected, and I expect c6 next (other options are pincer or approach q3 instead). Assuming he plays c6 I could then play k4 or l4 to set up the popular Kobayashi opening. However, even though I think the Kobayashi is a good opening I find it rather boring as it is played loads. Instead I plan to play r9 to set up the Chinese opening. In fact I think I probably have a higher chance of beating Magicwand with the Kobayashi (which can keep things a simple territorial game) than r9 (which will likely lead to large scale fighting where Magicwand may surprise me with good moves), but I want to make this game interesting :).

This f3-c6 exchange and then r9 is very popular with pros in the last few years. Usually it's not a good idea to approach and then tenuki, as then your opponent attacks the approach stone. However, there is a reason for doing it in this case. First let's consider the normal Chinese opening (with 2 white 4-4s).

A few months ago I was reading Go World 24 from 1981. It included a commentary by Hashimoto Shoji 9p of his game against Kobayashi Koichi 9p which consisted of him answering questions from readers of a Japanese Go magazine. In that game Hashimoto as black made the Chinese opening and Kobayashi played k3. One reader asked "Why not play as below?". Hashimoto said this is bad for white as black's move at q14 works well with r9; if white doesn't play from the top side he has space to invade and make a two-space extension from a to b, which he loses by approaching.

This rather puzzled me as I have seen this shape in many professional games so I searched GoGoD to investigate. The diagram below shows the next moves for white against the Chinese opening ordered by popularity. The image is the statistics from kombilo, the number underneath the columns is what percentage of games black won.

What struck me is that black only wins 45.8% when white approaches at the bottom side at n4, but he wins 55.7% when white approaches at the top. One has to be careful with interpreting win rates from kombilo as evidence a move is good/bad as often there aren't many games (or there could be other biases), but here there are lots of games and an early position so I think this statistics really can teach us something (45.8% wins of 347 games is statistically signficant at 7% level, 55.7% wins of 289 is 5% level). So it seems that Hashimtoto was right all along that approaching at o17 is slightly bad. Something else to notice is if white plays at f3 black only wins 44.6%, but there aren't so many games with this move. However, they do seem to be quite recent.

So I concluded that in the Chinese opening it is the lower side and the potential around the 3-4 stones that is more important that the upper side around the 4-4 stone (well, I already knew this, but it was nice to get some evidence). It is harder for white to settle a group between r9 and the 3-4 than between r9 and the 4-4 as the gap is one line smaller. Something else to note is that white's moves at f and g are a similar idea to the "Anti-Chinese" diagram I posted on my last move.

When white approaches at n4 black can answer at q5, but he only wins 44% of games this way which is pretty rubbish. A more active plan for black is to pincer at k4 or l4. If this happens, it is easy to imagine black liking to have made the exchange of f3 for c6 before making the chinese at r9, because if he does it later white may not answer so docilely at c6. A similar idea would be the below diagram, if black approaches at f3 after white has got a stone at k4 white would kick to attack black and make him cramped, c6 would be soft.

So, based on all these ideas that it is the lower side which is more important, I play at f3 as a probe first to ask white if he answers with the restrained move at c6, and if so I will make the Chinese and say f3-c6 was a good exchange.

But after tenuki-ing the approach you have to plan for it getting attacked. The plan is something like below: although f3 is weak, so is white's pincer stone, and in the running fight black will develop the bottom right moyo based off his Chinese opening.

i usually dont play this pincer...but if i play common knight move C6 i might fall in to a hole i can not get out.
althought below is playable said professionals..i think black is slightly better.

since i am playing as white..my move is very limited and all i can do is try to maintain balace.
and black has many many options.
strange enough black and white are equal given 6.5 komi..but options of each players are night and day.

Awwww, he prevented me setting up my Chinese opening. Whilst it's obvious how this pincer stops the Kobayashi, the reason it stops me playing r9 is a bit more subtle. Let's say I do play r9, white will obviously follow-up on my tenuki of his pincer, probably as below. The key point is after kicking to make black heavy and prevent him making eyespace (by sliding into the corner at d2) white plays at d6 on the 4th line as he knows there is fighting, and not c6 which is worse for fighting. Whereas if black gets the f3 c6 exchange before r9, then if this fighting happens black is happy as c6 on the 3rd line is less good for fighting.

So now, how to respond to this pincer? The easiest response to any 4-4 pincer is to take the corner which gives black territory, and white thickness and sente to approach the lower right.

What I used to do in positions like this is read to the end of the joseki (or rather just picture the joseki end position, it's hardly reading) and then use judgement to evaluate the position. However, there's no rule that says you must stop reading after one corner, you can carry on reading to help judge the position! With the approaches the focus is white's potential on the lower side. If white approaches low and black pincers white will probably counter pincer which looks interesting for white, so probably black plays as below to secure his corner stone and reduce white's potential on the lower side (later he can aim at f2). This n3 move is not common as a bit soft, but here I think it is appropriate.

White could also approach high. Similar to above, black could play a solid 3rd line move to reduce white's lower side potential (the Tooveli joseki).

What about attaching under the high approach? This is the best move for territory and indeed the high approach used to be considered usually bad as not good for territory, and only for special situations, though thinking has changed. If white hanes on the outside black is happy to get a big corner and a strong stone at o3 to reduce white's lower side potential.

However, white is likely to switch to the avalanche to develop the lower side. Something like below will happen and I prefer white. The lower side is not territory yet, f2 is unlikely to die, but white is developing nicely.

Because black is being constrained in his answer to white's approach by the white lower side potential, one idea is to make a shimari as an answer to white's pincer. Here I think white would then attack the approach stone. If black saves his stone the fighting looks better for white (he wants to play a next but the 2 stones are rather weak) and if black doesn't save his stone there's no obvious fuseki point to take instead.

If black is on the other 3-4 point the position is quite different. One very common opening is as below, the idea of white's pincer is to prevent black making the mini-Chinese. If black takes the corner (in gote) it is good for white as he gets sente to make the excellent approach at p3 which also develops the lower side.

Therefore black makes the shimari in answer to white's pincer. This shimari faces along the right side so q/r10 is an excellent move next. So if white does something to f3 black just plays on the right side. White could also wedge the right side and then black takes the corner. By making the p3 r10 exchange black has prevented, in sente, white from having an excellent move after black takes the corner.

So based on the above analysis I think taking the corner is ok, but I'm slightly unhappy to give white sente to approach my bottom right stone as I then feel I need to do slightly slow moves to counter the white lower side potential. So time to look for improvements.

You can always jump out when pincered, which could lead to this joseki or 9 could be a counterpincer at a or b (see viewtopic.php?p=86479#p86479). But that joseki kinda sucks and the counter-pincer seems to be giving up too much on the left side for dubious return on the right side (if I already have a stone around r9 or q9 it would be better) so I reject this jump.

Next up to consider is double approach which could be high (d6) or low (c6). In fact 2-space double approach at d7 and c7 are also being played by pros these days. One possible outcome is the sequence below. Black gets the corner in sente which means he gets to make the shimari at :b15:. This lower left sequence used to be considered joseki, but these days the exchange of :b9: for :w10: is considered somewhat bad for black as it gives white a to aim at (which aims at b: black can't block at b7 or white pushes through and f5 ends up on the right spot). See An Younggil's recent commentary http://gogameguru.com/go-commentary-yam ... ind-games/. In fact white could play :w14: at a right away which forces black to come out and then induces white defending at the bottom side.

The newer thinking from the Korean pros is to take the corner immediately. If white fixes at b black gets sente and is happy to have improved on the previous diagram as white can no longer aim at a. White probably tenukis to approach the lower right, and later black can pull out at b which is a pretty huge move.

White has another choice, which is to block this way (this is the reason for the hane in the old joseki, it makes blocking this way bad). In this variation white gets a wall and black the corner. I slightly prefer white here as white's extension from the wall will work well with d16. This variation is for when black doesn't want to lose the f3 stone, but here I am quite happy with the previous variation.

I did recently use this move at the London Open in the position below. My idea in that game was I wanted to make influence to counter black's centre potential, but this game is less developed so that's not applicable. Another game I used this move is http://www.online-go.com/games/board.php?boardID=212176.

So I still don't know where to play. Another idea is to approach the top left as a sort of probe which feels pretty cool. Magicwand's pincer is trying to stop me controlling the flow of the game, and this 2nd approach throws it right back in his face ;-). The basic plan is if white tenukis to play in the lower left I am happy to double approach the top left. If white plays docile f17 then I am happy to make that exchange and will play c6 as c14 helps c6 a bit. If white pincers then I dunno, it's complicated :D. It depends if the pincer is high or low but the plan is to choose a variation in the lower left the devalues the left side for white after his pincer says the left side is important. Then later I hop into the corner at c17.

Hmmmm, maybe this is why I spend too long on the opening and then lose games in overtime.... :scratch:

Not any more! In most cases I've started to think Black's too low and boring even for my tastes.
I've got a new favourite to replace it with. It's way more complex, exciting and leads to a much more dynamic position for Black.

Seriously... that's my favourite joseki (as Black). I really hope that's not too much a reflection of my personality...
