FORGET_ME
I am too greedy lol, I would have missed it, played QxQ then back to c6 and pick up the rook as well --- all the while knowing there is probably a mate but not finding it. This one should be used as a nice "guess the moves" puzzle.
That knight sacrifice really, really went bad, and it looked, on the surface, to be clever (though why anyone would drop 2 pieces for 1 rook, even without the attack the sac was not too well thought out) .... well played.
