Is this a draw despite the Stockfish evaluation of −5? I reached this position as Black:
[Title &quot;Black to move&quot;]
[FEN &quot;8/8/8/3q4/6kp/7R/6P1/6K1 b - - 3 46&quot;]

And I felt that I cannot make any progress and so it feels like a draw. However, Stockfish evaluates it as −5.1, though it also seems to be unable to get anywhere. So is this actually a draw, or is there some obscure line of play that Stockfish has missed as well?
This is a fortress and a draw.
The black king can't advance as the rook, shuffling between h3 and f3, prevents it.  The only way to break the fortress is to trade the queen for the rook and pawn, but the resulting endgame is still a draw.
