that was a terriblw game, u were losing and u won on time? gg? most of your 130 moves were random and wasted

Never before have I seen the FIRST pawn exchange on move 81 !

Thank you for your comments!

To chesslb: winning a computer on time happens very very seldom and only in very closed positions like this one.  It doesn't depend on your computer performance.

To tiger_knife: g7-g5 is an interesting option. However I didn't want to open up the position because I thought I would have less chances then.

To steevmartuns: great game by Nakamura. By the way, who is Nakamura: what is his title or rating?

dpakoh - on that note, the 50-move drawing rule has been a driving force behind a few interesting human wins over computers, most notably Nakamura vs. Rybka.

In this game, Nakamura sacrifices two (!!!) exchanges to give the computer player a strong material lead, but he also locked up the position to prevent any useful progress from being made. On move 174, the strategy pays off: Rybka plays the suicidal c4?? Nakamura's idea was that Rybka would do anything in its power to avoid draw by the 50 move rule because of its material advantage, even if that meant an obvious blunder. We can see the outcome. :)

(EDIT: in retrospect, 181. Kb2?? was also quite bad.)

Another key element of your win was the closed position.  In my experience, the limiting nature of such positions make for few tactical chances.  Naturally, a computer will out-tactic a human almost any day (due to deep vision), so narrowing the number of available moves helps to level the playing field.  In an open position, a computer can just rip you apart with unexpected moves and combinations.

Well done. It was interesting that the program didn't know what to do with its dark-square B, which ought to be a strong piece for it in the Winawer. It takes it until move 43 to get it on the right square (a3). If it had played a4 and Ba3 earlier, as Fischer used to do, this would have been better for it.

well i dont want to kill your joy with this is the only way beating a computer in a dead draw situation. see , computers dont want draw, they dont offer nor accept draws. that's why they have to prevent the 3 move repetition rule, and it takes time to calculate that. on the other hand human with a secure position just makes some repetitive moves and thus losing no time.(ofc human are happy with the draw against the computer)

It doesn't look like you had any advantage at all near the end, even though you were clearly better earlier in the game. That ending looks dead drawn without the time trouble. I think you should have played for g7-g5 when you had the chance; your queenside was adequately defended and I think it would eventually have been decisive had you opened the kingside. Thoughts, anyone?

You're right, that was extremely boring, but nevertheless congrats on the well-maneuvered win!

how can you win on time against computer ???

it probably needs some new cpu and ram ;)

Very good. You're right, the game was very dull, but after you traded queens, your advantage kept growing and growing!
