White to move

I think Rxd5 loses after Qxb2 2Kd1 Qb1
1. Rxd5? Qxb2+ 2. Kd1 Nc3+, or 2...Qb1+ (not mate) 3. Bc1 Nc3+ is the refutation.
Instinct is telling me to move the h1-rook, so I'm guessing 1. Re1 pinning everything on the e-file. 1. Re1 Qxb2+ 2. Kd1 Qa1+ 3. Bc1 Nc3+? 4. Rxc3 threatens mate on e7; 1. Re1 Nxg5 2. Qxe5 Bxe5 3. Rxe5 and e7 is indefensible.
*facepalm* ...aaaand allow me to refute myself. 1. Re1 Qxb2+ 2. Kd1 Qa1+ 3. Bc1 Bb2. Then I'm trying to make the defiant 4. Nd6+ and 5. Qf3 work, but it just looks bad. Back to the drawing board.
New to this website.. You guys trying to figure it out on your own, or are you actually just looking for the answer?
1.Nxg7+ eliminates the threat of Qxb2 and Rxd5 can be played afterwards, or is that too simple ?
That\s what I thought. But it seems a little prosaic.
Well, that line sacrifices the bishop on g5, so we still need to find the coup de grace after: 1. Nxg7+ Qxg7 2. Rxd5 Nxg5.
I don't fancy Remellion's line. Black can try 3..0-0-0 or 3... Bb2 rather than 3...Nc3+?
I for one really like the position after this line with Nxg7, or at least there are several options to consider:
How does black respond to Rc1? (with the terrible threat Qb5+). Or the immediate Qb5+ followed by Qxb7 and c6 and advanced passalicious?
The complete score of the game is in ==>(http://www.chessgames.com/perl/chessgame?gid=1061624)
Tal won this game with 1.Nxg7+ Qxg7 2.Rxd5 Nxg5 and now 3.Qb5+ Kf7 (hoping to find refuge at g6) 4.Rf1+ Kg6 5.Qd3+ Kh5 6.Rh1 1-0
@yeres That's the link for the Barcza-Ivkov game from your endgame thread.

Thanks for your rescue, caveatcanis. Indeed the link I gave was for the Barcza-Ivkov game.
