White has the bishop pair + pawn for the exchange - can white hold with optimal play here? The h7 pawn is worth less than the remaining pawns so it isn't quite worth a full pawn. Emanuel Lasker valued the rook pawn to be worth 0.5 points. Bishop Pair = 0.5 + 0.5 = 1.00 + 6 = 7 In this experimental position, black have 1 pawns advantage. Is it enough to win?

	If it were White's move then I would say White wins; however, Black takes the Knight and with the center open along with those sweeping Bishops, I believe that it is a draw. Anyone own an endgame database that can check it out, or perhaps someone could persuade Karsten Mueller to comment? Just a patzer, here...
