[d]4rk2/3n1p2/8/Q6p/2P1b3/1P4P1/P3K3/8 b - - 0 50


Position from your line, before 50..Bg6+

Here I would definitivenely consider 50..f5 to let the bishop on the diagonal
where the 3 white pawns could advance
(but f5,Bg6+,f6 or Ne5 are in same score range (+0.50 to +0.60) for hiarcs 7.32)


Now the score of 2 engines in this position :

Crafty 18.02 sees black better : -1.40 (50..f6)
hiarcs 7.32  sees white better : +0.50 (50..f5 and later 50..f6)



This position is very difficult to estimate "R+N+B+2p" against "Q+3 linked
passed pawns+1p" and the 2 kings are active

Here the help of a strong correspondance player who can analyse deeply would be
interresting !
