The following game is in some ways the opposite of the previous one. The game slides down the slippery slope from move 4, toward a Black win. White misses a chance to complicate the game, and perhaps take the advantage, at move 21. The game then continues to slide slowly toward the "inevitable" "0-1".

The game has gone its own way, with Black wisely castling-by-hand and White delaying the advance of his "Jerome pawns" until after the Queens have been exchanged.

The position is a bit more complicated than either player appreciates.
White realizes that 21.exf5 Rxe2 would be clearly to Black's advantage, so he moves his Knight to a safer square; but in doing so he misses a chance to mix it up.
Challenging is 21.h3!? as now Black's Bishop is in an uncomfortable position, e.g. 21...Ne5 22.Bxe5 or 21... Nh6 22. Bxh6 in each case followed (if Black recaptures) by 23.Rxf5 with an edge for White.
It looks like after 21. h3!? White has an edge after 21...d5 (or 21...Bxe4 22. dxe4 Ne5) 22.hxg4 Bxg4.
