Reminding everyone of how the previous thread went:

1) I start the thread with a puzzle posting a picture and the side that has the move
2) Person who solves the puzzle posts the solution (standard notation will be algebraic short K-King N-Knight R-Rook B-Bishop Q-Queen x-takes #-checkmate + meaning check +- meaning white's dominant advantage and -+ black's advantage)
3) Person who posted the puzzle confirms the solution (not only the first move, the whole variation at least including main lines)
4) Person who solved the puzzle is obligated to post next puzzle
5) Use to post pictures
6) Preferably don't use Fritz, Rybka, Shredder or any related chess engines
7) ...?
8) Profit! :)

Puzzle #1:

White to move, find the best move :)

Blacks last move was Nf5xh4, what should white do?

Rook can't move (pinned to the king)
If pawn takes white wins the queen.

It is the correct move but I don't think it would be an automatic easy win though for white....

... Qxe4
if Rxd7, Qxg4+ followed by Qxd7 will do
and I don't see other threat...?

Correct, Go ahead and post a new puzzle.

@Titron (below post) On 1...Qd4 Nf2! (and black only has a minor advantage ,if any) Qxd6 is simply met with Rxb7

Your suggestion on meeting Qxe4 with Rc4 simply leaves you a piece down. Possible variation could be 1...Qxe4 2 Rc4 Qe2 (attacks g pawn, and ties down white.) Black has an easy victory. Also note that after 2... Qe2 Rf2 is countred by Qd1+ folllowed by Qxd6. White won't be able to places a rook on the 7th rank, and also black is threatning Rf8 simplifing the game to an easy victory.

PS. You wrote Qd8+ in your main line, i assume you meant Qd1+ :) {FIXED}

additional: (chance of checkmate for white on g7 and h7 if Nd7 gallops away)
Qd4+

Rf2
(Qf2 gives up knight on e4 direclty. Same with Kh1 or Kg2 Qxe4+.
Nf2 gives up pawn d6 and allows threat to Rc7, black can start big promising offensive with one pawn more, white queen on f-line unsafe after Rf8, massive pressure on f2 and f1 with good pawn on e-line. Loss of knight or more realistic.)

Qd1+

Rf1 or Kg2
Qxg4+

now if white moved Rf1, white has to move Kf2 and black will play:
Rf1 -> white looses queen
(Kh1 -> Qxe4+ Kg1 or Kg2 Qg4+ Kf2, same result with queen and knight taken away)

if white moved Kg2, white should move Kf1 (Kh1 -> Qxe4+) and black makes:
Qd3+
whatever white does, loss of Ne4 seems to be predetermined.

Possible answer on previous presented solution Qxe4 is Rc4, then Qe3+ (Rf2, Qe1 won't help because of Kg2) or Qd3. White can play soon Rc7 and Nd7 will be lost after Rxd7. Open line for white with rook plus queen there doesn't looks great.

@TBest (above post) Right. Now i see it. Ty. :-) And Qd8+ should be of course Qd1+.
