# 4/27/2012 - Mate in 3

tooooo easy

immm. hard to imagine this queen sack..

Powerful!  If Black does not capture the Queen, the next move can be 2.Qg4#  or  2.Qg5#.  Black can protect one of these mating squares, but not both. So black captures, 1. ... exf4.  But now, the f4 square is unprotected, and 2.Nxf4+ forces 2. ... Kh4, and closes off both h5 and h3 as escape squares.  White's rook is protected by his f-pawn as he moves to 3.Rg4#

Another possible solution
1.Nxf4+ exN [.. Kh4 2. Nxg6+ Kh5 [..Kh3 3.Qg4+ Kxh2 4. Qg2#] 3. Qf5#]
2.Qd5+ Kh4 [.. g5 3.Qxg5#]
3. Qg5+ Kh3
4. Qg3#

More complex, but works.

I don't understand why Nf4+ doesn't work.

If - exf4 2. Qd5+ Kh4 3.Qg5+ Kh3 4 Qg4++

if Kh4 2Nxg3+ Kh3 or Kh5 3.Qg4++

Doesn't 1.Nxf4+ win in the same amount of moves also?

Since after 1...exf4 2.Qxf4 it's checkmate next move. 1...Kh4 leads to Rg4#

1. Nxf4+ exf4 2. Qd5+ ( 2. Qxf4 g5 3. Qxg5# ) 2... g5 3. Qxg5#

This should cover everything.  All the variations that you asked about for why 1. Nxf4+ fails should be in there.

very nice

difficult to guess the first move...

Q sacrifice!

mat in 3

way easier than Qg4/Qg5...

Easy.

When all else fails in a chess.com puzzle... Queen sac!

there are two solutions to the puzzle.

Nxf4+ pxf4 Qxf4 and there is no way to stop mate in the next move.

2.... Qe7+ certainly prevents mate in the next move - and probably ruins the whole attack.  After white protects or moves his king, black might advance his pawn from g6, and white's chances for winning are doubtful (and certainly no mate in 3).

Not too tough, I knew it involved in a queen sacrifices but I didn't see the rook move

Good puzzle; good day.
