  morfishine: Yes, 20...O-O is the biggest advantage of 20.Rxf7 vs 20.Nxf7
Jul-03-13  TimothyLucasJaeger: Looks like white overlooked 22 ♘ce4 (22 ...♕xf2 23 ♘d6+ ♔d8 24 ♘e6#).

This was difficult. I failed to consider black's best defenses in 20 ...♕c4 and 20 ...♕c6 in my initial analysis.

  gawain: I guessed that 20 Rxf7 was the way forward but then I got lost in the ensuing complications. I'll have to look at the position with the aid of an engine

  kevin86: I saw the key move,but like yesterday,got caught up in the complications if black DECLINES the rook sac.j
Jul-03-13  gars: a tough puzzle, this one!
Jul-03-13  BOSTER: <geniokov> <after 20...Qc4 white has a strong reply like 21.Ne4!!>.

But what is wrong with 21...Rc6?

BTW, I would play , maybe 20.Rxd7.

Jul-03-13  BOSTER: <blunderclap> <I was thinking Rxd7 Nxd7 Nxf7- it seems to me It's a very nice position for white>.

This is correct only if you don't know that black can castle when his rook under attack.

  morfishine: <rogl> On your comment: <if 22...Qc4 I think black is busted after 23.Nce4> Yes, Black is probably busted. I looked at that and thought Black could fight on after 23...Rc6, but it doesn't look too good after 24.Nf6+

  perfidious: <rogl> and <morfishine>: Black is dead lost in the line 22....Qc4 23.Nce4, for precisely the reason <morf> adduces.

  Pedro Fernandez: 21.Ne4 doesn't work because 21...Nf7!, and if 22.Nf6+ Nxf6 and 23.Qxe6+ is not possible because the black queen controls e6 square. Certainly 20.Rxf7! wins the game but also 20.Nxf7 it does because white wins a knight against the black's best defense as may be easily verified.

  ajk68: Does anybody have a conclusive finish from where the game leaves off?
Jul-03-13  Patriot: 20.Nxf7 looks winning:

20...Nxf7 21.Qxe6+ Kd8 22.Rxf7

I'm not sure what else here for black.

Jul-03-13  Patriot: Ok, so 20.Rxf7 is better. I examined that move as well but thought 20.Nxf7 was more forcing due to the dual threat Nxh8 and Nd6+.
Jul-03-13  tbentley: Count me among those who missed 20. Nxf7 O-O. Both Nxf7 and Rxd7 would be winning if black couldn't castle, however.
Jul-03-13  tbentley: I've seen castling as a double attack before, but I don't remember seeing it as a double defense before.
Jul-03-13  bischopper: i think take with horse f7 but he take with horse too wow one momen now I understad it is with rook

  FSR: Hmm. I saw 20.Nxf7 0-0! and wasn't happy. Somehow the idea of sacking the rook on f1 instead never entered my mind.
Jul-03-13  schweigzwang: I guessed Rxf7 and even found Qf2 following, but then I was lost.
Jul-03-13  BOSTER: This is pos. after 20.Nxf7 0-0 with white to play.

<Pedro Fernandez> <certainly 20.Rxf7 wins the game , but also 20.Nxf7 it does , because white wins a knight against the black's best defense as maybe easily verified>.

This is interesting to see.

Jul-04-13  geniokov: <BOSTER> I saw this position already in the diagram you have given above but i´m not convinced for White because it doesn´t have any good continuation!

Let me say,you play 20-Nxf7 0-0 21.Rxd7 Nxd7 22.Qxe6(with an idea of dis.ch. by removing Knight to h6) but Black will play 22..Qc4!(forcing exchange of Queen and attacking Rook at f1 as i have mentioned earlier!)23.Nh6 dis.ch.+ Kg7! (now that BOTH f6 and e5 squares are protected by Knight at d7) How can you proceed?

Jul-04-13  geniokov: With my variation given above,that makes me unhappy about <20.Nxf7>.
Jul-04-13  geniokov: 20.Nxf7 0-0 21.Rxd7 Nxd7 22.Qxe6 Qc4 23.Nh6 dis.ch.+ Kg7!(What else?)By playing 23..Kg7,i will surely exchange my Queen to rook at f1 because White´s Knight is en prise too at h6!
Jul-04-13  geniokov: After <20.Nxf7 0-0> White´s feeling was he was hit by a "vaccum cleaner"forcing him to give everything he can give even the position at the end was UNCLEAR! White´s problem is that his King has no breathing place yet! It can backfire anytime to him!
Jul-04-13  nikhil17311: black made too many mistakes.
he should have capture the pawn at e5 with his knight at d7
