I assume that black doesn’t have enough time / moves to stop the B pawn from eventually queening (without giving up a piece) and that’s why it’s advantage to white?
Qe2 is the winning move for black. It threatens many things. First, it attacks f2. Second, it pins the f2 pawn and threatens Ne3+ after which pawn can't take as it is pinned, and if bishop takes, Qxc2. On top of that, black's bishop is too strong and there will be Rxb2 at some point as well. So yeah, Qe2 and black wins.
@@pablourosa1443 To be fair, it is not really my find. I just unraveled what Coldflow said with some help of the engine (and trying out different moves for white). Nothing seems to work. Either loss of material, or checkmate in some lines. It turns out Qe2 does a lot of things plus it keeps Rxb2 in reserve. I am pretty sure Stjepan saw the fork, but as he said that source of counterplay is the bishop and rooks in a and b file, plus he mentioned the plan where the queen attacks f2, so he must have thought Nc7 is too dangerous as it opens the file for the rook, or just assumed it doesn't work because of those things and didn't even consider it.
Basically a blitz game

4:16 Why couldn't he do Nc7 forking the rook and queen?
Qe2
Rxb2. If Nxa6, Rxc2 and your knight is weird and f2 is attacked. If queen moves, then Rxf2 with a big headache
