Played a game against GNU chess (2400). Here's the game with detailed annotations.

After playing humans for a long time, I decided to try my luck against GNU chess, a very strong chess engine but not as strong as Stockfish or Komodo. I have a healthy respect playing against computers and I knew that GNU would be a very worthy opponent.

The time control I chose was 45|45 which I thought would be manageable. I was not likely to face severe panic inducing time scrambles that inevitably lead to gross errors.

Just one stupid little move could cost me the game. Fatigue, eye strain, psychology etc. all play a prominent role in human chess and I had to steel myself to try and play like a machine. I went into the match with guarded optimism.

Playing against a program like GNU is not a walk in the park. GNU is absolutely merciless punishing errors, is annoyingly patient and has a perfect memory for openings and endgames. Computers almost never blunder tactically, although they can make major strategic errors. It was this strategic deficiency that I wanted to exploit vs GNU. I hoped to steer our battles to quiet maneuvering trench warfare that requires judgment and foresight rather than brute calculating ability.

After a good night’s sleep I was ready for mental combat with GNU. I vowed to myself: "Stay under control, don't get tactical!" ... I checked and re-checked my openings and opened Arena GUI. Here's how the game turned out.

You don't have to say it thrice. And WTH do you quote such large posts?

Sorry then, I thought you were a spammer. Lots of them around here these days.

I think your game commentary was a bit unfair. While, indeed, GNU chess had little progress to make on the queen side for the majority of the game, it had a huge space advantage there, which meant easy maneuvering for its pieces and easy lateral defenses - I think you underestimated his defensive resources. "Never underestimate engine's ability to defend" is the first rule to follow when playing a computer.  And GNU chess is a veeeeery resourceful engine, I've never managed to beat it on the hardest setting.

After white's 42nd move, however unbelievable it looks, Stockfish says the position is equal. White has all its pieces on perfect defensive positions, and black's hopes to break through the defenses aren't big. A human probably couldn't defend that, but GNU chess calculates like a savant and sees the defense routes far further than a human player could ever hope to.
