If three of those were >present, it assumed "stonewall"... This doesn't seem to match... What if the pawns are for black?? In these examples of Pablo's games; black pawns: a5,b6,c5,d6,e5,f6,g5,h6 definately stone wall with black. white pawns: a4,b3,c4,d5,f5,g4,h3 partial wall, but two strong pawn chains. The code was removed (19.15) so Crafty doesn't recognize anything like that now? Joshua Haglund toneewa@yahoo.com
