How the other 17.2 got +1.something is beyond me, >>as it has a huge penalty for trading a bishop for two pawns... > >3 pawns. 1 Bxh6 gxh6 2 Qxh6 f5 3 Bxf5... you are looking too far ahead. Check the original Rebel output... 3 moves only, Bxh6 gxh6 Qxh6 and there the captures stopped. But even a piece for 3 pawns loses most of the time, unless the pawns are well advanced and mobile... or unless it is an attack that works of course...
