Go up one level in this thread


I am new here and dont know how to show a diagram of position but if u copy this
game and load in chessbase u can find it easily. The blunder can be found easily
using Fruit 2.2.1 at move 70. Rb4 by white is the blunder this is where score
changed from draw to win for Fruit 05/11/03csom-

Its interesting to note when i put Rybka in analysis mode it doesnot show 70.Rb4
but it played it in the game and lost !?

Also Rybka didnot know 70.Rb4 was a blunder even for futher more moves.

777: Rybka 1.01 Beta 9 - Fruit 05/11/03csom- Rated game, 60m + 15s 2006
8/8/8/1K4pk/3R3N/5N2/1q6/8 w - - 0 1
