Today's game was with 2 stones handicap against a 7k, which I lost after a big group of mine died, and featured numerous other L&D mistakes. I definitely need to get the tsumego habit going again.

Last night I went to the club up in Winchester for the first time, and it was great! It was in a very good pub close(ish) to the bus station, and I played a game against one of the members, an 8k, and also the club secretary is going to pass on email addresses for some other players closer to me in Southampton. Unfortunately both of us liked to take our time over moves, so the endgame was a little rushed as the pub was closing, but it was a very close game. My opponent recorded it and sent me the SGF, so I've reviewed it below. My theme (once we got into the midgame around the time of the centre invasion) was to play moves on the side of overplay rather than conservatively, and I think it went pretty well. Any further comments from people more knowledgeable than I are welcome. And just 10 days to go until the tournament! It's nice to be confident that my estimated rating is pretty close to what I seem to be playing at.

- move 13: yes, h17 normal locally, but play lower side fine too. White doesn't need to add a move, so it's not like you need to rush to punish him for being naughty. - move 15: blocking is slow, you let white get 3-3 in sente; either extend to r9/q10 to help your group, or tenuki and be prepared for white to attack with a pincer. - move 19: when the 4-4 already has the extra stone, and they have lower side extension, knight's approach is probably not a good idea (unless you are a super strong bot). d3 attach is a standard idea: you either get a chunk of the corner to help you settle along lower side, or go into corner. 3-3 invasion also possible, the outside isn't so big with a nice reduction point at k4 for later. - move 27: yes pincer first so white is under pressure. Also o4 rather than o5, lean on the strong group to be more forceful as you want to get out in sente, not gote (or if they ignore you want a big follow-up, o5 doesn't have one). Your problems here stem from the r4 block mentioned before. - move 35, not really clear what this is doing, you can even go as far as f18. dutchie wrote: And just 10 days to go until the tournament! Bar-low? I'll be at the Candidates which runs parallel. |

Sunday was the Bar Low tournament in London! It didn't go quite as well as I'd hoped; I decided that I'd be pretty happy if I could win half my games, but I ended up with a final record of 0-5. I didn't keep records of the games, but overall I think I struggled most with the time control. 25 minutes then 25 stones in 5, increasing to 30, 35 and so on felt really brisk, and I often ended up using way too much time thinking in the opening and early midgame, leaving not much thinking for late game. Games 1 & 2 I was never really ahead, and in the end both of those opponents went on to win all their games. I'm more upset with the latter 3, all of which I went into the endgame if not ahead with a decent winning chance. Game 3, while I was feeling nicely ahead going into endgame, my opponent played a very deep invasion right as my main time ran out and it all fell to pieces in the ensuing complications. Game 4 was a 2 point loss, which really could have gone either way. Game 3 was again annoying, this time I was playing way too fast in the overtimes. Worst moment was after restarting the clocks from counting out overtime stones, I connected a 2 point atari when there were way bigger moves left. Ended up losing by 10. Still, it was a fun day out, and nice to chat to some other people playing go! I played a couple more games on KGS tonight and didn't manage to break the losing streak, so I'm feeling a little discouraged at the moment. Hopefully a little sleep will fix that and I can post some sensible analysis soon. |

So after that post, I went on a truly ridiculous losing streak, which must have been well over a dozen losses in a row by the end (counting the tournament). I don't remember how a lot of the games went now, and maybe I'll review them some other time, but I finally broke it on Tuesday and got another win just now! I'll post up both of the games, with a post game review on today's since my opponent stuck around. Any thoughts welcome as always!

Another couple of games tonight. The second had aspects of a thing I've noticed happening somewhat often in my games where I just suddenly end up in the midgame with a bunch of influence and no territory and I do a terrible job of converting it all into points. Any tips and a review greatly appreciated!

The first move that looks funny to me is  . You need to make a base (and this move doesn't really do anything to Black's group on the left, which is totally alive). Extend to H3; it threatens Black's group as well. and  also don't feel right; you're forcing Black to connect two groups and make territory. The C14/D14 stones were potentially weak; now they're fine. You kind of owe a move at F16 or F17 to finish that pattern off; another big point is O17. : One usually plays this at J4 and then jumps back to G4, but I don't like this much anyway, since Black is not weak so there's nothing much to attack. If you're going to play in this area I prefer the shoulder hit at L4. Of course your wall is not doing much but I wasn't a fan of its creation in the first place.

A few comments. Main focus: White should make life difficult for Black. |

My reflex would be to play B3 at move 19. But I notice that no reviewer suggests it. Any opinions? |

Thanks for the reviews all. Seems like I misevaluated the E3 cut at various points and need to play a little more forcefully. |

Ed, 3 as clamp at 4 is maybe better, but still as black has k3 I wouldn't be sure to get a good result. So 2 looks playable to me, at least not easy to refute if it. Also black could play 2 at 4, then white doesn't have the choice of the clamp variation, only this cut one, or just submitting to crawling and taking sente (which might actually be ok). |

Instead: Now black has to allow the connection underneath. If he fights it, the cut is horrible: Black must play 6, or white kills by playing it himself. Then 8 is forced or 2 dies. I'm not going to claim that B3 is a forced win, but it seems to give black some serious problems. |

Hi dutchie, Do you have access to Leela, etc. ? Curious to see a nice engine's evaluations for  ,including E4 and B3. |
