puzzle 10 : Nxf7 [naar puzzel / to puzzle]
This position occured very recently in the World Rapid & Blitz tournament 2024, New York. Alireza Firouzja had White (in round 3?) but he did NOT play Nxf7+! although the commentators suggested this move. Probably he was unsure if the complications would be in his favour, because Black can capture this kNight in 3 ways but all are good for White.
