Hi everyone. This is a game I played today on wbaduk. I had black and won by 3.5 I would appreciate some ideas on my fuseki. I know I made mistakes in handling the middle group and lost some points on stupid places during yose, but I am mostly curious about my fuseki and direction of play in early middle-game. Thanks for the review.

Congrats on your win. One thing I noticed: this shape occured in your bottom-right corner. Try to make a ko:

Please take with a pinch of salt:

Move 9: somehow, this feels... odd. It might be fine, but at least to me it has the feeling of a move that only half accomplishes a few goals. I'd prefer to either go all the way and kakari the bottom left stone, or to just make a second shimari (never bad :)); or of course to extend the top left stone (very big).

Move 13: at this point, I would prefer to have the J3 stone at K4...

Moves 17 & 19: the shape is a bit thin, no? Instead of 17, why not pincer, for example at L17?

Move 21: doesn't really build the corner, so I'd prefer to cap at L14 and build center influence instead.

Moves 23 & 25: might be necessary, but feel painful to me. They give the feeling that something went wrong earlier (like 17, 19, 21).

After this, I think many dubious things happen in the fighting, but I'm not strong enough to be really sure about which particular moves should be where. In particular though:

Move 84: you get lucky here (I think). If white would play 84 at G10, what are you going to do? If you answer, you cannot make two eyes any more. If you don't then G9 cuts you and you are about 200 liberties behind in the semeai.

Oh... And learn the tripod group :)
