I was not talking about correspondence game but about tournament games but
It is not unbelievable to blunder in correspondence games and the main reason
for blunders in these games is clerical errors.

In the game against England my opponent was sure that I was going to capture his
knight move so he was probably too lazy to check if I really played did it.


I believe that he used Fritz for analysis but it did not help him to see that he
is analyzing the wrong position.

Here is the game
My opponnet(SIM from England) said that he wrote my 29.Nxg6 as 29.Bxe4 so after
30.Nxh4 had to resign

Note that Fritz likes 29.Bxe4 even after a long search because it is not
materialistic enough when other programs find 29.Nxg6.

29.Nxg6 wins a pawn when 29.Bxe4 does not win a pawn and small search depth is
not Fritz8.008's problem.
