Bf6 Nf5+? although in this diagram, there is no black pawn on b5. The BT2630 position is easier to solve, it appears to be a position constructed using the Blackburne position as a starting point. I don't know why this was done, but it's interesting to wonder about. To get from BT2630 #17 to WAC #141, move the white bishop from d3 to b3. Thanks for answering. I bet you still get the WAC position in a second or two. bruce
