Cannot Solve Mate-in-2 puzzle. Please help.
WOW, mikeman, thank you so much. I have been trying and trying to solve that puzzle. I never even thought of castling. What a tricky puzzle. This site rocks.
If white can not castle, there is still a forced mate in 3. I'll try to enter it here as a no-castle-option extension to the original puzzle. Full disclosure: I used fritz engine shootout to find it. Edit: the title on the puzzle below should be You vs Blackberry (if mate in 3 no-castle-option.) The title on the game below that should be Me vs Rybka.
