Took me a half minute longer because I assumed it would be a queen-sac puzzle like so many others. Once I realized that wasn't it, the answer came quickly.

Good puzzle.

Took me a little longer because I thought the low number of White pieces made it simpler and I thought that the pinned Bishop would play a part (tried Nc5+ first).

Lovely solution anyway, especially for a real game.

I loved this one. It had all of the elements that I respect in a puzzle: Elegance, simplicity without being obvious, under-promotion, and of course, the hero being my favorite piece.

In old style composition problems no piece was superfluous; the the extra pieces seemed to play the role solely of a distraction trying to disguise the under promotion to knight. At first I looked at a knight check and only then noticed the possibility of a promotion - fairly rare motif. Once the existence of the possibility was apparent the answer came of itself.

This wasn't a composition, it was a game continuation.

If I didn't know it was a two move mate, I never would have gotten it. Nice.

demorei um pouco, excelente a promoção cavalo
