This is more of a suggestion than a question. I think it would be really helpful to have an "endgame" variant, where both sides would start from a relatively equal position in the endgame (games drawn from an endgame database). I'm primarily a 10 minute 0 increment player, so when I get to the endgame, I'll usually have 3 or so minutes remaining. I do ok, but have a hard time improving my endgame. Many times I just completely blow a drawn or winning position. I don't want to switch to 15,10 games, but I would like to get better at endings. I feel like this would help my game (and many others' games) drastically.
