This mate in 3 begins with white playing N-f5 discovered check. Black is virtually forced to play N-e7. (If black plays K-e8, mate follows with Q-c8, if black plays K-g8, white sacrifices the queen with Q-f8 check and after Kxf8, white mates with R-c8.) So, after black plays N-e7, white mates in two with Q-c8 check, black plays Nxc8 and then white checkmates with R-c8.
