Outro problema "impossível": as Brancas jogam e dão xeque-mate em 2 lances!
(Another "impossible" problem: White to play and give checkmate in 2 moves!)

ExcluirVerry nice
ResponderExcluirDonex7 seems to be right about everything except:
ResponderExcluirif 1. ... Nxc2
2. Nd4#
Any non-king move results in immediate mate by Nd4 due to the discovered double check, combined with the knight attacking b5 and revealing the queen's attack on d7, the king's only remaining escape squares.
Nc7 results in checkmate, but only after some interposing block of the rook check (taking with the pawn or blocking with the pawn or bishop), then Bd5 gives mate in three.
1. Nc7 Kb5
ResponderExcluir2. Qd5 CHECKMATE! :)
1. Nc7 Kb5 2. Qd5 # CHECKMATE!
ResponderExcluirSorry, i was mistaken.. its checkmate in 1!! 1. Nc7#

Thank you all for the comments!
ResponderExcluirThe correct move is Qg4!! No matter what Black responds, there is checkmate immediately:
1. Qg4!! gxh6 2. Nd4#
1. Qg4!! g6 2. Nd4#
1. Qg4!! Bc5 2. Nd4#
1. Qg4!! Bd6 2. Nd4#
1. Qg4!! Bxc4 2. Nd4#
1. Qg4!! Kd7 2. Nxg7#
1. Qg4!! Kb5 2. Nc7#
1. Qg4!! Kd5 2. Ng5#
1. Qg4!! Nd5 2. Nd4#
1. Qg4!! Nxc2 2. Nd4#
:)
What's wrong with the other suggested moves?
ResponderExcluir1. Nc7+ ...
... gxh6, and there is no checkmate in 2 moves...
1. Bf7 ...
... Bxc4, and there is no checkmate in 2 moves...
1. Nc5+ ...
... Bd6 2. Rxd6+ Kb5 3. Na3#, it's only mate in 3.
1. Na5+ ...
... Kxb6, and there is no checkmate in 2 moves...
@PCFilho
ResponderExcluirAfter Nc7+ there is a mate-in-2 with following Ne5# or Qd6# (depending on black's response), am I right? :)
Dennis,
ResponderExcluirThe continuation after Nc7+ leads to checkmate, but only after 4 moves:
1. Nc7+ gxh6
2. Bd5+ Kd7
3. Be6+ Kc6
4. Qd7#
The only move which leads to a forced MATE IN 2 is 1. Qg4!!.
Of course, what a fool I am - after Ne5+ the bishop on b6 is not guarded anymore... :|
ResponderExcluirMate is not forced in 2 after 1.Qg4 if 1. Qg4 Kd7 2. Nxg7 Kd8.
ResponderExcluirMate in 2 is not forced after Qg4 if: 1. Qg4 Kd7 2. Nxg7 K8.
ResponderExcluirPhase V Technologies,
ResponderExcluir1. Qg4 Kd7 2. Nxg7#
The Black King can't go to d8, because the White Bishop is attacking this square...
Nc7+ Bd6 Qxd6#
ResponderExcluirdarpit shah,
ResponderExcluirAs I've already written above, Nc7+ leads to checkmate, but only after 4 moves:
1. Nc7+ gxh6
2. Bd5+ Kd7
3. Be6+ Kc6
4. Qd7#
The only move which leads to a forced MATE IN 2 is 1. Qg4!!.

ResponderExcluir1. Qd4 f3 ... ?
ResponderExcluirAh 1. Qg4 f3 2. Nd4#
