質問: I have a position which the engine gives as favorable for black *(black to move)*, but I am confused on what plan should black adopt, as white has a dangerous passed pawn and black doesn't; also exchanging the queens doesn't look good as the black knight is too slow to catch the white pawn.![enter image description here](https://i.stack.imgur.com/4A05K.png)
回答: Black's best hope is for a perpetual by something like ``` [FEN "8/8/8/2p1p3/2Pp2P1/1knP4/3q1QK1/5B2 b - - 0 1"] 1... Qg5 2. Qf5 Qd2+ 3. Qf2 ``` The question is can White's king escape the checks, maybe via g3 and h4, and then get in g5 when only white can win? I think the key is for black to try and keep his queen on the c1-h6 diagonal, be able to drive white's king back from h4 and prevent g5. If he can do this then he can hold the draw.
