man, I spotted, and what I spotted, is basically that I posted one position instead of another.

after b4 fg5 bc5, black first plays Qf6 (why give the d4 pawn? ), Bd3 (seemingly nothing better) and only now Bb7:

[d]r3r1k1/pb3p1p/5q2/nPP3p1/3p4/P2B1N2/2Q2PPP/2KR3R w - - 0 7

now, this is the position which is very difficult for white, though you need depth; black plays Rec8/d8, a6, etc.

Bg4 instead of Bb7 is also possible and seemingly also good for black.

PS. and I was just wondering where did the black edge evaporate after Nd4, as I have been seeing mostly lines favouring black, but when you post another position, nothing to wonder about...

check also this one, playing straigth away a6 instead of Bb7:

[d]r1b1r1k1/5p1p/p4q2/nPP3p1/3p4/P2B1N2/2Q2PPP/2KR3R w - - 0 7

to see how much astray Houdini is in judging white has the advantage.

but the position is relatively complex: there migth be moves engines and humans alike do not see.

and just not to say that I am making up claims again, on above diagram, white has almost no acceptable move:

- ba6 loses
- c6 loses
- Nd4 loses
- Bh7 is very hard
- Be4 d3 black is excellent

so, about only moves white can try to hold with are Rhe1 or b6, but, if you let the engine calculate longer, those are also very good for black.
