First I thought this is the losing position, where white plays Nf5 with rook
exchange but loss of the white a-pawn. But try against Tiger, it shows 41.Rb7!
This is a very fine move which keeps the advantage and cares for the connected
pawns. Main line is:
41.Rb7 Ra2 42.Ng4! a5 43.h4! (creates a free pawn for white) gxh4 44.gxh4 e3
45.Nxe3 Ra4 46.Kg3 Ra1 47.h5 Rh1 48.Kg4 a4 49.Kg5 a3 50.Ra7 with a clearly won
position. After 12min Tiger changes to 50.Nf5 +7.xx.
It is probably worth trying the other top programs, I will try Rebel and Junior
on it.
BTW I have some games too where Shredder already evaluates +6 or +7 and ends in
a draw, but these cases are rare.
