It seems to be a truly deep yet forced combination.

Here is Glaurung 2.1 x64 running on a 2.2 GHz Core Due laptop:

Hiarcs 12 MP on Core2Duo found Rh1 in 1 minute 16 seconds. Here is the eval after 6 minutes.

Yes,it's a forced combination,look at the queen on te other side of the board doing nothing,leaving it's black king exposed to attacks,not to mention the corrupted pawn structure in front of the black king :!:
Damn,why do most of the strong engines get into these bad positions when I play them :lol: :?:

I just look at this and it seems equal : the 2 first white moves are : Rh1 and Kg2
