We see that score goes clearly up for white after few moves. It's a
pawn up for white now.
The rest of the game is even with a killerbook at own risk of course,
i'm currently seeing many time losses of diep, and positions like:
Crafty versus Diep (Judgeturpin or DoctorWho i forgot what account)
<PRE>
- = - = - = - = ... 1 ...
= - = - = - = - ... 2 ...
- = - = o = o = ... 3 ...
= - = - = o = - ... 4 ...
R o k = - O - O ... 5 ...
= - r - = - O K ... 6 ...
O = - = - = - = ... 7 ...
= - = - = - = - ... 8 ...
wow what does WWW mess this up!
</PRE>
black to move
position white Kh3,Ra4,a2,f4,g3,h4
black Kc4,Rc3,b4,e6,f5,g6
black to move wins easily
Believe it or not, diep managed to lost this as it didn't play Ra3,
it played Re3.
This is so simple, but i haven't worked at endgame yet.
Diep needs about a minute to see that Ra3 wins!
So even a simple won position doesn't garantuee anything at blitz especially,
but at 2 minutes a move, or in Sweden at slower hardware
3 minutes a move, and commercial programs which have worked
at their weak points, it gets harder to mess up.
Then +1.xx out of book and having positions which your prog plays
well, which you know in advance, is a huge advantage.
