I'm in a game at OGS that is now in move #441. I've captured 121 stones thus far; my opponent 32. (It's a truly awful game; I haven't resigned in disgust only because at this point I want to see if my opponent will call it quits before it literally becomes impossible to move.)

What's the most moves you've ever had in a 19x19 game?

Maybe it is a Bot, I think some Bot's play it out because they skimp on implementing endgame counting. Though I think that at some point you should be able to have everything pretty much solid and should make some profit by waiting it out, IE not filling in your territory or giving your opponent stones.

On another note I have often wondered what are the expected lengths of games what are the expected length until resigning and also what is the lowest scoring winning games. I have played games where I have won with as little 36 points.

No, it is definitely a human and not a bot. Bots don't post game invitations. :)

It wasn't me, but I saw a guy play a game on KGS against a bot with (iirc) about 32,000 moves. His strategy was to build a spiral so that ~180 of opponent stones are snaked round and then in atari, capture them and then repeat for ~179, ~178 etc. (Quick back of envelope calculation says sum of 1 .. 180 is 16k, double for 2 players gives 32k). I was impressed that KGS/CGoban didn't explode!

I mean the total captures+territory+komi, unless you actually had a whole board seki.

That makes more sense. Generally over the board you play territory - your own captured stones, and with large ko fights you can end up with a negative score. I don't think I ever did territory + captured stones except online where I don't pay as much attention since it's nice enough to show you the difference.

Here's a game I won with 25 points against 15.5 (OGS uses territory-captures like on-the-board Japanese):

Your comments on the game say something about a scoring error? What is the problem?

It had counted c1 (and maybe a1?) as dame, it's correct now. That problem was fixed years ago :)

Wow. I wouldn't have thought that even theoretically possible. Any chance you have an sgf?

Afraid not, it was many years ago. Maybe if someone else remembers his name we can find it in the KGS archives. I think it had a 'c' in it...

Pardon me, but I'm skeptical. That's really weird behavior even for a bot.

To believe that it happened, we have to believe that a bot
1) Manages to place ~180 stones without making a live group.
2) Continues to play even when tens of thousands of points behind.
3) Allows each side to make one contiguous group.

I'd assume it was a primitive bot with a very limited set of responses. I can't imagine any reasonably modern bot would be that hapless.

My game is now up to move #463. Has anyone personally exceeded that?

I once played a game with my brother which lasted about 550 moves, deduced from the amount of prisoners exchanged. I had told him that if there is a triple ko, the game is "no result". He then made lot of single ko's, which I won one by one.

It was IdiotBot or similar: one of those that plays randomly and then likes to run around the first line in atari. Once it has some stones in atari it will keep playing out doomed ladders so is very predictable. Maybe he used undo if the bot spoilt the required pattern in its random move phase.

I had a friend, who is now on the road the becoming a grandmaster of chess, I played alot. He was by far the most agressive player I met, if anything could be attacked. We played in a tournament I held and it was 1 hour no byomi. He litterally only lost by time out. I eventually beat him soundly in a game arranged by our teacher, by forcing him into mistake driven positions. He got so greedy, and wanted everything you could have, he realized chess is the only game he is good at; he just can't get the concept of compensation. Last time I heard from him, he had one a nation wide tournament, and his floor is 2000.

I think my personal best is around 300. Although I seem to recall playing a 38x38 one time, which we didn't finish.

And another one sorry that uberdude can't find that huge game right now. Pity, would have liked to have seen it.
