According to my count, white is solidly ahead, by more than 5 points (even counting the fact that it's black's move). In fact, given that this is a professional game, maybe they would even call it "game over". Which is interesting, because not so long ago I had the feeling black wasn't doing bad at all.

Of course, since then, white's center group has been 100% solidified with points, whereas black's center area now looks much smaller than it did then. But still...

I think W has been ahead for a long time. By my count, W now leads on the board, even without komi.

Wow - I'm really bad at counting the score during a game (which is part of the reason I don't do it enough), so it's reassuring to see that 4/5-dans can't even agree about who's winning in a given board position :)

it is not that we can not count...it is that i am too lazy and dont have time to count accurately.
i recounted and i confirm that white is ahead by about 5 points because it is black's turn.

Ouch, there goes black's little area... My endgame is really not good enough for accurate predictions, but maybe something like this now?

This is sente - white will now bamboo I suppose. dfan, if there is a sente exchange like this, maybe you could just upload a few moves in one go (especially with sente exchanges); it'll help speed up the game. In an endgame like this, writing comments at every single move is just too much...

One problem is that at my level, it's not always obvious just how sente a move is and whether the opponent has to make a real decision about whether to answer it or not. But if it is super-obvious, I'll try to post pairs, and if someone guesses the move I'll update early.
