This is getting ridiculous. I solved this immediately because I had been fooling aournd yesterday trying to compose a puzzle with the same idea for the key move.
It was bad enough when kingdawer was finiding anticipations for my ideas after I posted the puzzle. Now's it happening before! Has the NSA bugged my chessboard?
This one took a while for me. I saw that a black pawn or knight move would walk into mate. But ignored the king because I thought it was too far away and there were 3 waiting moves it could make. I looked for a queen move to cover e6 without giving up the other mate threats for the longest time. I finally gave up and realized that the king could help if black moved his king to e6.
