  Dionyseus: I thought it'd be interesting to have Rybka 1.1 (arguibly the strongest engine ever programmed) analyse this game between these two old programs.

Rybka thought Belle's 33...Bg4 was very weak and should have played instead Re8. After Belle's 33rd move Rybka evaluated the position as white being two pawns up.

It didn't like white's 41.Re5 at all and instead wanted to see Be5.

Belle returns the favor with an even uglier move 41...Bc2? Be6 would have been much stronger.

White's 47.Rd4 was weak, much stronger would have been Kd4.

White's 51.Kd3 is horrendous and blows away a two pawn advantage. Rd6 was needed.

White's 64.c4???? is easily the worst move in the game.

Jun-24-12  rwbean: Didn't computers suck 35 years ago? I just put it through Houdini 1.5a at 90 seconds a move, but I'll give it a bit longer tomorrow with tablebases enabled. 57 ... e4+ should be a losing blunder, because of 58. Kxe4 Bxg4 59. c4! (>+5) and similarly 60. c4! (>+5) is an immediate win. Even 61. c4 draws. There are various other blunders all over the place - for instance it thinks 58 ... Kf7 is still a draw.

Houdini wants Black to play ... f6 on moves 14, 15, 16, and 17, and 38. g4 and 41. g4 are also very powerful.

Jun-27-12  rwbean: Ok, here it is more systematically, through Houdini 1.5a at 360 seconds a move - the 11 worst moves in the game (each makes a difference of >1 pawn to the eval - the difference is given by figures in brackets).

16 ... Qc6? - should have played 16 ... f6 (1.62)

17. c3? - should have played 17. Ng5 - eval +1.05 (1.47)

38. Ke4? - should have played 38. g4 (1.19)

41. Re5? - should have played 41. g4 (1.51)

47. Rd4? - should have played 47. Kd4 - eval +3.07 (1.67)

51. Ke3?? - should have played 51. Kf2 (1.82 - back to even after this)

And then the five worst moves are all in the endgame:

57 ... e4+?? - should have played 57 ... Kf7 drawing (3.75)

58. Kf4?? - should have played 58. Kxe4 winning (3.73)

58 ... e3?? - should have played 58 ... Kf7 drawing (4.30)

60. Ke4?? - should have played 60. c4 winning (5.05)

61. Kf4?? - should have played 61. c4 drawing (1.99). After this White is lost.
