Here is a game played between two 3 kyus at a tournament.

The time limit was 65 minutes each, followed by 30 moves in 5 minutes overtime.
The game was decided in overtime, as often happens.

Both players learnt to play more than 30 years ago, so there are sure to be some
deeply-ingrained faults to get your teeth into.

I included a few comments to show what I was thinking during the game.

Some comments (for both sides):

14) Good. A low pincer seems appropriate here, to make efficient use of the stone at Q14.

16) I would be inclined to block the other side. This way creates thickness facing left, but in that direction B has a perfect reducing move (shoulder-hit at K4). The other block creates thickness facing up, which somehow looks better to me, although B still has a weak point to aim at (invasion at R12). Probably both ways are playable.

31) Nice move at the focal point of competing moyos. The shoulder-hit is still a good alternative, but now that B has a stone at F11, I like this move.

32) Fast but a little thin. For example, B can attach at G3 and cross-cut in response to a W hane. H4 would be safe and thick, but then B would get J6. I am not sure what is best for W here.

33) I think this invasion is an overplay. W does not really have much territory here, as B can make a large reduction starting with S8, so there is no need to invade deeply. From W point of view, I would be happy to see this move. My plan would be to attack, not expecting to kill, but with goals of defending the Q8 cutting point, building thickness to prepare an invasion at M17, and even consolidating the moyo on the bottom.

36) Severe and good, but a little thin. Consider P9 as a thicker alternative. This would still prevent a B connection along the right side, but it would also connect solidly to R8 and help build the W moyo below.

37-39) are inconsistent. B should just attach at P14 directly, without fixing the shape, making it harder for W to respond.

44) Instead of this soft splitting move, consider a hard leaning attack at O13. If the B side group runs, W would get immediate profit from a hane at N14, breaking into the B territory above. If B defends above, P11 looks like a kill.

46) Why not hane at Q9? That would be less severe but stronger toward the center. B might get some sort of ko for life along the right side, but that would be a fine result for W.

47-57) settled the B group nicely, making the invasion a success. W managed to secure the moyo below, but should not really be satisfied, as he left too many weaknesses behind.

61) What is B doing? The cut at Q7 captures three W stones, which is a pretty nice way to live.

66) is purely defensive. This looks like an opportunity for W to fight back, playing against some of the B weaknesses in this area. Jump to M15 or attach at N14 for example. At the very least, attach at K13 and push a few times before connecting, to leave B even thinner above.

69-71) is a large yose sequence, but there are much more important plays on the left and top sides.

72) I still like the idea of exploiting the thin B position above, before B has a chance to reinforce. M15 or K14 or even L16 look good.

73-83) Good strategic decision by B, much better than simply defending. The attack in the center should allow B to consolidate the top, more than compensating for the loss on the left side.

95) Peep at J9 in sente, then extend to F7, and W is in big trouble. If you are worried about life for the large B group, play a few forcing moves around O7 to secure life (after the peep).

The fight got complicated after this, so no more comments. This was a well played game, with many dan-level moves on both sides, so don't take my criticisms above too harshly.

Mitsun,

Many thanks for your comments. It was most interesting to find out how many times each
player overlooked a chance to take control of the game. More flexibility
in our thinking is needed.

I will play in another tournament tomorrow, which may show whether I have learnt anything.
