Hm, i dont see the idea. Neither does my proggie. It says just +1.41
for white in the final position of the game (move 45). It prefers
36. Qb6 and evaluates it as +1.60.
What you mean by penalty for having opposite bishops? Phalanx's static
eval just steals lots of points from material advantage in opposite
bishops endgame. No rook, no queen, no knight can be onboard, just
pure K+B+pawns versus K+B+pawns.
