Prettier than 3 R d6 is 3 Nd4 double check Ke7 4 Nc6 Kf8 5 Qh8

-chess is part art -

Can't see exactly what ArcticKnight is doing there, but 1.Nf5 check is definitely the move- a retreat by the king to g8 or f8 is going to lead to 2.Qh8#, and taking at f5 is going to allow 2.Qh6+ followed by 3.Qh8#, and 1...Kf6 is met by 2.g5+ and 2....Kxg5 is met by 3.Qh4#, and 2....Ke6 is is met by 3.Rxd6#. So, mate in three with best play.

1 Nf5 Kf6 2 g5 Kd6 3 Nd4-c6
