Test your engines trust me its fun!!!

Up to depth 22 it is the unchanging opinion of Houdini that the position is equal:
Stockfish 4 (64 bit) evaluates Bxh7+ as about equal at first, but as +4 and rising after about 30 seconds (edit: actually it hits +1.81 after 12 seconds).
If Bxh7 is executed (after I refreshed the cache) it takes Stockfish about 5 seconds to go from about equal to +4.

At what depth is this? Is it single PV or multi PV ?

In multi PV mode both Houdini and Stockfish quickly finds Bxh7+, but in single PV mode none of them.
paste the following position in your chess engine and then play the move B*h7 and see what happens first it will favour black and then after a while it will favour white.....blind spot of engine LOL
tell me if ur engine can find the sacrifising move and in how much time
