Time for more bad chess intuition...

Both of these positions are slightly better for black, but still playable:

[D]8/5rbk/6q1/1p1Q4/1PpPN1p1/5p2/5PP1/3R2K1 b - - c0 "After Ne4, black will play
Rf4 or Rf5";

[D]8/5rbk/6q1/1p1Q4/1PpP2p1/2N2p2/5PP1/4R1K1 b - - c0 "After Re1, black will
play Rf4";

All other choices lose the game.
