This is nice.

Nice adaptation!!!

I'm sorry, Arjunrama, I forgot to mention 2...Nxd8 3.Qe8#. Similar mates are in the side variations, but it should be mentioned in the main line too.

Crux, thanks for taking up my cause. A word of worning though, in your line 5...Qc6+ 6.Qg7!?? (sort of #) Qxg2!??, not just 6.Qg7 is an illegal move, but also 6...Qxg2. I'm sure you knew that, but I thought it worth mentioning, because in over the board play, in normal time controls the position before the first illegal (i.e. after 5...Qc6+) would be reinstated, but in blitz you can claim the game after your opponent makes an illegal move, before you make one. Thus, in Blitz in the above scenario, after 6.Qg7, black could claim the game, but waves his rights by making a move. That move is illegal (capturing a king is illegal), so now white can claim the game. A friend of mine used that very sleazy trick to save some utterly lost games in a blitz tournament.

oh sorry man... i found that checkmate if the knight takes the rook..

why doesnt the black knight take the rook?

why give a piece while u can get it for free?

sorry mate but not very cool. QG7 is mate and all other combintions are of no consequences

Glue, if it were legal, that would be mate, but 5...Qc6+ is check. It is because of that that it appears at first sight to be an adequate defence to the mate threat.

6. Qg7 is mate

cool

"More puzzles from the future", maybe.

Cool, you should have posted this as a puzzle in the "more puzzles" section.
