LiKao and I played this morning 8AM EST.

I won, W+R.

Game is extremely messy. Not a proud win, but a win nonetheless. Comments on the game are appreciated.

Agreed!

I need to look over it closer anyway...know a few things I thought about during the game - and how my middle game play kind of fell apart...

@danielm: maybe you should look back at the final position of your game vs. Hushfield from last week. By my count, with proper endgame white wins by 1.5 point. So white's resignation seems a little bit unfortunate...

Lesson here: never resign too early! :geek:

gaius, can you show your endgame sequence? The best I can find (from white's point of view) is a half point win for black.

It might be possible by winning the ko on the right as last move of the game and correctly abusing blacks weakness in the bottom left. But the part with ko as last move makes my head hurt.

This is only to show the idea. Both players are a bit slack and I didn't play out the ko fight.

Aaah, I miscounted slightly! White does win, but only by half a point. The trick is that white needs to find the tesuji of exchanging B6 and D8 first, and then playing B7. Then, black has to play twice in their own territory to capture white, which makes a point difference compared to LiKao's variation.

AGA rules uses stone counting, right? I did not take that into account, but it should not matter since white gets the last dame if he uses the B7 semedori. So white does not need to (and should not) start the half point ko. And black should not get the opportunity to start it, since T4 should be white's first dame after playing B7.

I am counting by hand by the way, so I hope I didn't miss a point somewhere...

EDIT: this seems one of the rare cases where stone counting with 7.5 komi produces a different result than Japanese counting with 6.5 komi. Interesting!

Black has to spend two moves to capture, but white has to spend a move to protect on the bottom.
