Marco Costalba 3713bb26ef Don't increase mobility if attacked piece is defended by a pawn ... If an enemy piece is defended by a pawn don't give the extra mobility bonus in case we attack it. Joona says that "Paralyzing pawn" is usually worth of nothing. On Joona QUAD after 964 games: Orig - Patch_2: 191 - 218 - 555 (+ 10 elo) On my PC after 999 games at 1+0: Mod vs Orig +227 =550 -222 50.25% 502.0/999 +2 ELO In both cases we tested against the original version (without increased mobility), not against the previous patch that instead seems to fail on Joona QUAD: Orig vs. Prev.Patch: 237 - 217 - 627 (-6 elo) Signed-off-by: Marco Costalba <mcostalba@gmail.com>		2009-10-03 10:48:07 +01:00
