user19648: I found this position in the Chess Programming Wiki. It's a perft calculation. In the depth 2 the results informs that there are 3 checks. But I just able to find 2 checks:


Kf1 hxg2+


Kf1 Bxe2+


.
[FEN "r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq - 0 1"]

Where is the third check?
May look stupid, but I really can't find it.

user4418: 
Kd1 Bxe2+ looks like it is another depth 2 check
