Is this it?
1... Rh1+ 2. Bxh1 Qh2+ 3. Kf1 Qxh1+ 4. Ke2 Re8+ 5. Kd3 Qf3+ 6. Kd2 Re2+ 7. Kd1 Re3+ 8. Kd2 Qe2#
Edit: Another variation:
1... Rh1+ 2. Bxh1 Qh2+ 3. Kf1 Qxh1+ 4. Ke2 Re8+ 5. Kd3 Qf3+ 6. Kd4 Re4+ 7.
Kxd5 Qf5+ 8. Kd6 Re6+ 9. Kd7 Qf7+ 10. Kd8 Re8#
Edit: Both my variations have the same mistake. Ignore them.
Final edit: Given white's back rank problems the move has to be one that removes the back rank defender. So the move is a queen sac. Bishop takes queen, pawn takes queen and then mate only can be stalled and not stopped. I think I got it right this time. In OTB I don't thin I'd see it in a million years. This almost looks a like a study. Bery pretty!

Originally posted by vipiuYes the same thing happened to me. But after I saw that Rh1+ didn't work I had to look at something else. But this was only saw because I knew beforehand that there were tactics on that position. On a real game situation I'd certainly look at Rh1+ and then in case I saw the whole thing right I'd dismiss that move because it lead to nothing (actually I think one can go to a perpetual at most) and look for other things.
I think the nicest thing in this problem is to not be afraid of cxb7+...I dismissed the solution because of this check...
But what made me understand why the winning move is a winning move (rather than just calculate things out and see that in fact a win is possible) was my previous faulty line. It dealt with white's back rank weakness but of course the queen move dealt with it in an efficient way.
How Anand saw that one in a rapid game is something that I think eludes almos everyone at this site.

It's a logical process - the bishop's stopping the mate, so let's get rid of it. Then seeing that the check on the King is just a distraction - it has no future. Simple really, but certainly not so easy.

Originally posted by buffalobillOne can easily see the forced mate after Bxf3, and one can calculate that the black king will be safe after a few checks, but what is more difficult to visualise is that the queen on f3 also covers h1 despite the bishop standing in-between, making the checkmate inescapable. That is a pattern to remember.
