some comments:
1)the hardware of movei crashed few times during the game and I replaced to the
slower hardware of the tournament.
Movei is certainly weaker than sjeng but there is a known principle in chess
that is the principle of 2 weaknesses.
one weakness is not enough to lose the game and you need 2 weaknesses so based
on this principle it is possible that movei could draw with equal hardware
against sjeng because one weakness of weaker software was not enough to lose
the game.
2)Movei got a better position from the opening and could get the advantage by
20...f5(the expected move based on the pgn).
Movei could not find it in a reasonable time in analysis after the game and I
guess that I need better evaluation(I think that I know what to change in the
evaluation to make it find it).
ahud lahav(I may mispell his name) found it after the game and movei agreed
after analysis that black is better but the evaluation was similiar to the
evaluation after 20...Rxe4 that was also better for black.
Movei blundered somewhere in the endgame but it seems that humans are weak in
this phase (at least in case that tactics of mate threats is relevant)and if I
need to choose between human analysis without programs and programs analysis
without humans then I prefer the analysis of chess programs espacially when
programs(except movei that crashes if I give it a fast hardware) can run for
many hours on strong hardware to analyze when humans are going to be too lazy to
devote hours.
