Many thanks, Andreas!

So it seems that the brilliant 17... a5! could save the 10... Qc5?! line. A pity that SF doesn't give a full main line there. The position:

Fascinating line! That means that black also can make a draw by playing 10... Qc5.

Here is the position after 25...Rxd3!! (26.Qxd3?? Qe1+ or 26.axb4?? Rd1+ both lead to mate, in the last variation 27.Ke2 Ng1 mate is pretty):

OK, +0.52 doesn't look bad. But if we continue that line: 20.Qg3 Bxg3 21.hxg3 Qxb4 22.Bd2, I must say that I really like white here!

6.Kxf2 Nxe4+ 7.Ke3 may give a a minimal advantage for white but it seems that 5.Bxf7+ is better and the question if programs can find it.
