From a recent game of mine against a player rated over 1800. I think this is a good puzzle to show, especially to new players.

Very Interesting

cool

nice:)

Rook or Queen that pawn, either works. If playing OTB, I would play e1=R+ for fun :).

very nice ... hehe

 thanks this is good one...

easy to see and once you see it, it's easy from there on. I saw it because im always looking for queen sacrifices (but never finding =P lol). good checkmate :)

Can't believe i got that in 2 secs  O.o  but it's probably coz the bishop x-raying the king makes it obvious =/

And it's cool that no matter how white responds to the discovered check it still leads to checkmate

very good
