SL-GentleKiller:

Oddly, I've played a game or two at IYT and never had an inkling of this. Also, I don't find it particularly logical considering that other moves on a turn are considered simultaneous (e.g. you can't move two pieces to the same square even if one of them will disappear in an attempted capture.) Still, just being aware of it helps and I can think of a position where the problem can't be solved by move order.
