30 seconds to survive or die

Last evening, playing Black against Paul Kemp in the Bury League, I was faced with this position after White’s 30th move (Ne4-g5).   With only half a minute remaining, I missed the saving move which would probably have drawn the game.

White is threatening Nxf7 checkmate, so I can’t take the queen.   But White has three pieces attacking h7.

Now you know there’s a good move for Black, you’ll probably find it easily.   But with only 30 seconds to think, I missed it and soon lost.

30… Rf1+!
