Life In 19x19

Hello.

Below a game of mine.
Any comments welcome.

On , attach at P4. W did not jump out from the LR corner on , so make him pay for it.

Sorry, I'm testing on an iPhone, very difficult to do Go on this forum on an iPhone! More later.

At move 6, his play is the wrong direction.

11: I would have attached at P4. You have the ladder breaker at D16, so it should work well for you.
Though I can't say that your move is bad.

20: You clearly have built the better position here. He has two weak groups.

21: This seems overly ambitious. Your Q6/R6 stones don't look strong enough to play like this. The leaning attack at P10 looks better.

27: This move betrays the whole theme of your previous moves. To be consistent, you have to play something like T11 or S12 or O10.

Hello,

Just a few points that caught my eyes :
Puts some pressure on white, but what for ? If the goal is to build a wall in the center, then it should be followed by at O10 (or earlier at O9).

Puts pressure on white but what for ? Black gains some thickness but it is facing white's and the corner group didn't need reinforcement.

Puts pressure on white, but what for ? At this stage I would be concerned about finding a way to use the e4-h4 wall, maybe cutting at m10 ?

A few random thoughts.

Hi iseijin,

Note: I am only about 8k, so please take my comments with a big grain of salt. If anyone better disagrees, please let me know!

But I have been studying openings recently and here are some things in the opening that stood out to me:

seems like it just invites White to play at R10-11 and spoil your influence, I would expect something more like the chinese opening.
Lucky for you, is in the wrong direction.
might work better as an extension around R10, that way White still can't spoil your influence by pincering you.
/ seems like a bad way to pincer though, because it leaves the corner very vulnerable.
: I bet you could get a lot of profit from exploiting the weak corner. I'd guess playing at P4 would be the best to totally surround White. There's also aji around 3-3 point. I'm guessing you could get enough power from that to not make up for you lack of base.
: Might be bigger on the untouched territory on the left.
seems like an awkward attack, White cut through the weak point you left. I'd imagine attacking the top group (Which looks very weak to me) or playing the first move on the left would be better.

Perhaps you know all of these ideas of opening theory and are intentionally violating them, I certainly couldn't tell you if your opening ended up better or worse than if you'd followed these guidelines. But I hope this provides you some help!

FYI, Nick Sibicky 4d covered most of these ideas in a video:

Thank you all for your thoughts.

Shawn Ligocky, I had the same considerations or thoughts about , , , and .

My reason for playing : I believe pros have played that way.
My reason for playing : When white pincers my approach move, I take the corner. This way I already have a lot of territory. This should be playable for black.
About : I'm not sure if white needs to respond to this move to protect her lone stone, but if she responds, this naturally is better than first playing in the bottom left corner, as black can still do this now.

That's a good point, playing sente before gote sounds good

By move 76 Black has more or less lost, so I won't review moves past that.

leichtloeslich demonstrated a nice variation on this. Your move is very passive, granting W opportunity to develop both sides.
This seems very questionable. By making W stronger you are also making it more difficult for your bottom group. Solid extension downward would've been a strong move.
I kinda like the net if you block here. It would've been a bit tricky but it should've been playable. O9 however is completely unplayable. I would rather see you tenuki completely than play there. After that move, you are losing badly, but luckily there is still a lot of room to make up for it. If you manage to win hard on bot or left, you can still win. Now the priority should be to get there first.
W could tenuki now, play on the left side or bot, and that would more or less be end of this game. This move should've been at bot, and W answer to this should've been at bot.
Decent trading up to this point. Kill or severely attack W and you may win this.
If this move was at C16, it could've been a game. It wasn't. What saddens me the most is that B seemingly didn't even fight back. This was the last stand, and even if it would've been difficult, at least it would've been an attempt to come back. But there was nothing.
Classic "Please resign now" move.

That's the cursory overview of the game. I didn't go that much in depth on purpose, because I think the main issue here was that the overall strategy was weak. Individual moves were chosen to support a bad strategy, and as such, even if moves fulfilled the purpose you gave them, that purpose itself caused you to lose. The only small-scale tactic that had significant effect on the game is the corner joseki leichtloeslich demonstrated in his review, at move 11.

I don't think it's really about sente vs gote so much as strength vs weakness. If white replies to the attack it is obviously a profitable exchange, but I think perhaps white shouldn't reply and that doesn't mean black's move is wrong. Your suggestion also seems viable as far as I'm capable of judging (though I do prefer the game move), but that's because I see both moves as different ways of profiting from white's weakness. i.e take a big point while white plays smaller moves to settle his group, or attack directly and ensure that white can't make a solid group in the area.
