I implemented some small bonus for captures in latest movei when the idea is
that if you have captures and the opponent has no captures then even if the
captures are bad captures it has an advantage.
I increased the bonus in case that the attacker has positional advantage not by
captures.
I also implemented some small bonus for weak pawns based on the question if they
are attacked
The result is bad.
Here are examples

Movei played b5 because it believed that after Qxb5 Rb8 Qe2 Rxb2 black had
a better position and saw too late that Rb8 does not help and it has to lose
material.
later in the game
black has 5 captures and white has no capture but it does not help black.
The bonus for captures was increased because of positional advantage for black.

I already posted a game of movei against amyan when movei did not find the
correct moves also probably because of the bonus for captures.
r2q1rk1/ppp2pbp/2nnb1p1/8/5Q2/2NB1N2/PPP2PPP/R1B1R1K1 w - - 0 12
I still believe that some bonus for captures should be productive but probably
I should do better analysis and not only consider the number of captures.
I post here 2 more interesting games when movei lost.
The first game is another interesting game when I believe that movei had a
winning position and lost.
It may be interesting if somebody can analyze the game and tell me when movei
blundered.
I believe that the endgame should be better for white because rook bishop and
knight are better than a queen and a pawn.
The second game is a game when there were too many passed pawns in the board and
movei did not know what to do.
It may be interesting to have the mistakes of movei and I suspect that it is
easy position to make mistakes even for computers.
