Actually I was wrong. I'll delete my other post. You see those two buttons at the bottom left of the board in post 1 ? I think the answer to your question is there.
I'm thinking so too but that hangs the rook at a8 though. Doesn't look simple. Like for example Qb3 b6 Rd1 Ba6ch Ke1 Nd3ch Rxd3 Bxd3 Bxa8 Qxa8 f3 Rd8 the analysis board is giving black an advantage of about 3 there.
Black to move, can you find the only move that keeps a huge advantage (-3.6, second best move gives -0.9), I missed it in the game
