Movei totally agree that Qd1 is a loser but it evaluates the position as equal.
I do not understand how can tiger say +4.46 for that position.

You can see that movei predict the line of the game in the first 4 plies of it's
main line.

Here Movei that knows nothing about protected passed pawn does not agree with
crafty and prefers b5 that allows c5

Here movei see only a small advantage for black but it seems that I did not give
it to search deep enough:

Rg2 is losing a pawn but tiger seems to be unable to count material correctly in
that position.

you mean 61.b5
Movei also does not understand it and prefers Rg4.
