I noticed a force draw in my game that I missed, fortunately my game still ended as a draw. Here's the puzzle. white's move the lead in a forced draw was Rg5??

Note, this is not actually a forced draw, but the the other way I win a rook.

48. Rg6 Rxg6+ 49. Kh5 loses the rook for white as you say, but it wins the game.
