Some notes on the the early game:  is fine. Don't worry about these details until you are ten stones stronger  It is much much too early to play something like  . Even later in the game this would be a very weird place to play. Q10 or R10, blocking White's extension from his shimari, is the most obvious place to play. : At some point you should play the sequence B7-B4-C7-A5 in sente to wall off the left while forcing White to capture your stones.I would play  at C14 or D14. That big space you are leaving behind you is not territory, especially since you are open at the bottom.Generally you leave  for later because you might want to play E18 instead and threaten to connect out to the right. : Now might be a good time to play that B7 sequence and take the whole left side pretty securely. should definitely be at R14. Throughout this whole sequence you are giving White a lot of territory and making a wall facing nothing that he should then be able to largely nullify by playing Q10 (which he should have done earlier).Get used to answering the O17 approach to the star-point stone with R14. Responding by playing out into the center as you did twice here is a technique for special occasions. |

After b7 it looks like this: now if white answers we get: if B plays first, we get something like this: If I count right, the followup is about 14 points gote. THis is a big endgame move, but an endgame move, so w should asolutely not answer B7 right now, but instead play at H3 where you correctly blocked(nevertheless, B7 is big, it just isnt sente). Following up on that, on 27 you should absoultely continue blocking out at H2, defending at H4 is unnessesary(have you read ladder/net?).and blocking is important. After your 27, the side is later still open at j2. |

I guess the defending move at H4 was kind of automatic, I didn't really think about it being necessary or not. Something to watch out for. |

Quick comment:  Tenuki. (Play elsewhere.) Also, the solid connection makes bad shape.

Looking at the end result, perhaps  was the losing move (technically, 81, which was outright bizarre)You jump two points in the vicinity of enemy stones. That's often vulnerable to a cut. In this case a keima would have been better. In general, when you expand your moyo while reducing the opponent's, check if the expansion can't be easily cut. Veel plezier! |
