Find the Best Move

The following position appeared in my 15 mins game .. Find the best move for black in the puzzle below....

I missed it in my game (though i won).. I found the move after the game..

White just  played  QC5, can you spot blacks best move? Houdini gives +4 after blacks next move :) 

how about Bxe3, after 25. fxe3... Qf2, Bf1, Qf3 pressures rooks and bishop

if instead of fxe3, 25. Qxe3... Qxf2, Qxf2, Rxf2 with pressure on the e2 bishop. 

edit: Realized i could try to solve right on the board there, at first didn't realize the bishop was covering the King. Good stuff 

I found Qxf2 but winning material from there isn't automatic -- take a look at 

24...Qxf2 25.Kd2  now, I'm sure Rybka sees how to seal the deal, but all I found were lot of interesting tactics and complications and odd defensive resources. Take a look. 

24. ... Qf2: 25. Kd2 e4 looks promising, because 26. ... Rd3:+ seems to be a serious threat. 26. d4  Be3:+ 27. Kc2 28. Qe2:+ loses two bishops. 26. Rhe1 Rd3:+ 27. Kc1 Re3: loses a bishop.

But after 26. Qg5: Ng5: 27. Bf2: Rf2: 28. Ke3 is the advantage to white. However, after 24. Qf2: 25. Kd2 Rf3 do I think that white can resign, because he will lose at least the bishop on e3. I see 26. Rhf1 Qe3:+ 27. Qe3: Be3:+ 28. Ke1 Rf1:+ 29. Kf1:  or 26. Qe5: Re3:.

Yes you are right.. but the bishop cant be saved... If white tries to save the bishop by Kd2.. then another puzzle follows...

hint: Pin against king is more deadly than pin aginst queen

Very neat!

@zoom2me... yes Rf3! That looks like the move I was having trouble finding. 

@Zoom2me and @JG27Pyth: did you both not read my variants? I am already stating that Rf3 is the move that wins for black.

Sorry sir. You found it. :)

Thank you, that's sports!
