The post that was quoted here has been removedI went through it with Crafty. Just before the knight sacrifice Crafty (given less than a minute) assesses the positions as +0.73 and suggests 22. Rfd1, after the knight sacrifice it assesses the position at +0.45; so the sacrifice is ok., the evaluation keeps bouncing around (it hit 2.12 at one point) which means that black had better watch out. Black should capture with the f pawn. Crafty gives 23. Qh6 straight away, and puts the rook on g1 after Bh5 because of 23. ... e6 24. Qh6 Qf6 when black can defend; it rates the position then at -0.19 (after 5 minutes) so it's not a disaster. After that the only other thing it points to is on move 31. Qa5+ you had Nd5+, although I think that that's engine stuff; your method simplifies into a straightforward(ish) won ending, whereas the engine wants lots of complications.

Basically as far as I can tell once you were out of database/book moves you got it pretty much right, apart from 23. Rdg1 which lets black off the hook, but doesn't actually lose.
Originally posted by idiomsThe line Crafty gives after 23. Rdg1 is 23. ... e6 24. Qh6 Qf6 and black defends, because the queen is covering h8. After the immediate 23. Qh6 it gives the line 23. ... Bh5 24. Rdg1 Rc5 25. Ne4 Qc7 26. Nxc5 Qxc5, when black's had to surrender the exchange.
