I just played and reviewed a game on OGS. I'd mostly only been using it for correspondence games before, but I had found that it was sometimes difficult to find a game on KGS or Tygem at my level, and it was pretty much instant there, so maybe I'll play more.


IGS is also a very good source of games at the DDK level.

Here are some comments on your first game. I thought you played very well. I like that you had a clear plan from early on -- focusing on building territory on the top, bottom, and center -- and toward that end you identified strong moves in support of those goals. Here are a few things to think about in general:

1. You do a good job of identifying key moves for your goal, but you seem to make large gote moves without thinking first whether or not there are supporting (or important) sente moves that could be made first. (move 53 for example).

2. You need to be a bit more careful with your connections. At times, you are too focused on extending and not sufficiently focused on maintaining the connection. For both moves 15 and 33, you would have done better to make a smaller extension to avoid being cut.

3. I think you are at the point where you could think a bit about how to gain moves by harassing opponent's weak stones. Moves 47 and 55 are examples of when this could have been useful. They are also examples of sente moves you can make before making other moves.

4. This is a more challenging comment, but I think it might be good to put it on your horizon. In this game, you developed a single plan early on and you were able to execute it. That is a very important step. You should feel good about that! However, part of the reason you were able to execute it was that your opponent allowed you to do so. At some point in the next few rankings, your opponents are not going to be so cooperative. To counter this, you'll need to be more flexible in your strategic thinking. For example, you might build a moyo, knowing that it might get invaded, but with a contingency plan in mind for the invasion -- such using the invasion to build another moyo somewhere else or as I illustrated in my comments, use the invasion to invade the opponent's moyo. For example, players often think of the main goal of developing a moyo is to claim the territory inside. However, that's not always true. The better way to think of the value of a moyo is that it threatens to claim the territory inside. That threat will either yield an invasion or territory, but you want to build the moyo in such a way that you will benefit either way.

Thank you for the comments BG! Lots for me to think about there. I'll try to think about finding more sente moves in my next few games.

I'd heard that sort of thing about moyos and their purpose before, but that's the most succinct way I've seen it expressed.

Oops, again it's been a while and I've been too busy with PhD to play any games. I played again last night and just finished posting up a review, with help from a few comments from the #go IRC channel on Freenode. SDK by June may still be within my grasp, despite my inability to keep up with my target!

Nice game. You played well! Here are some thoughts.

General areas to focus going forward:
1. Try to think about whether stones are worth saving before you save them. I think you both should have sacrificed a few in this game.
2. I think you are missing opportunities to threaten opponent's groups by not recognizing when they are weak or where they can be cut.

I finally managed to get another game in. Not keeping to anything like my 1 game a week target, but I have decided to retroactively clarify that my initial target was SDK by the *end* of June (since that's halfway through the year it's more or less what I had in mind anyway). So here is a soul-crushing game in which I snatched defeat from the jaws of what seemed like a well-fought victory in a 2-stone handicap game on KGS.

I can see that you are focusing on the order of development early on. And on a number of occasions you had the right idea in terms of general strategy. Unfortunately, while you had the right idea, you chose the wrong implementation at times. Keep at it and the right decisions will come. Below are some comments for you to consider. Another thing to consider is the shape of your wall on top. It would help to be more careful about not letting your opponent create cutting points or other defects in your wall, particularly in a game like this.

Hi dutchie,

:b6: cut, good.

:b8: Not so good. Drop to S5 first.
Study the local variations after S5.

:b16: OK. ( BG: :b8: was first mistake, not here. )

:b30: K17.

:b38: Study the variations if B N3.

:b52: o18.

Just a couple of days left to hit my target of SDK by end of June, I just played another game on KGS. Annoyingly my ? has returned, guess I should play a few more games to lose it.

Was a fun game, until I made several really frustrating mistakes in endgame. I'd be interested to see what best play would have made of the middle too.

Hi dutchie,

:w30: Almost a pass.

:b31: W almost passed with :w30:, so that's good for you.
( AlphaGo would have some good candidates here. :) )
Tricky: if J13 is enough for B to win, that's one possibility...

:b35: Did you consider G16 hane first, before here ?

:b41: Did you read E16 first, before here ?

:b45: The hane exchange ( :b45: - :w46: ) may be OK, but did you consider M17 first, before :b47: ?

:w48: Strange.

:b49: Of course, sente is important -- which is why you shouldn't have connected on :b47: --
you could've tenuki'd.
It's a good idea to get a rough assessment of the board, before :b49: .
( My feeling is B is comfortably ahead. If the final score was only B+1.5, then something bad happened from here. )

:b53: Your idea here is OK, but your shape is thin. ( e.g. C13 is still big. )

:w54: If you played here yourself on :b53:, you would also be nicely connected.

:b61: Did you read F12 ?

:b71: Did you read L10 atari ?

:b95: N14.

:b99: Did you read L9 ?

:black: 101 Did you read L9 ?

Ed Lee is right that something must have gone wrong and it was the sequence in the middle starting at f5.
I would like to point out though, that this couldnt have happenened if you had earlier played some throw ins in order to take your opponents eyes and liberties away. It wasnt strictly needed, since you kept is group dead, but it would have given you an easier time, if you reduce his liberties, so that capturing races in case of a cut like f5 are less scary. In fact, for example at move 130(the same trick applies in easier form already at move 127 and 129), you can even capture in a ladder using those throw ins(!), though ins, I thought this was nice:)

go to move 131.
also check move 147
