Gotta love draws.
116 Moves :D

...especially drawn-out draws.
Erm, wait, why has this even ended in a draw? There was actually no threefold repetition, and the 50-move rule hasn't kicked in either. I therefore gather that your opponent agreed to adjudicate the game as a draw (which admittedly would feel more like a loss to me if I was them; I though that mating with K+R vs K was common knowledge).
