This is amazing.
The material was equal Queen Bishop and 4 pawns agsint Queen bishop and 4 pawns
and tiger played 39...d2 with evaluation of 4.59 pawns advantage for black.

and there is no material advantage in the main line of tiger at move 39.

Here is the relevant position

[D]7k/5Bbp/1q6/8/4pp2/2Pp3P/1P4P1/5Q1K b - - 0 1

Crafty17.13's evaluation is 2.50 pawns for black at depth 10 and 2.53 for black
at depth 11 and 2.63 pawns at depth 12
Crafty wants to play 39...Be5

Crafty's main line at depth 11-12 gives black material advantage(Be5 Bd5 Qxb2
Bxe4 d2 Bf3 Qxc3)
