re the original msg, i have definitely played at borgata on weekends where 20/40 was a better game than 10/20 - last saturday was an excellent example

i would caveat that players in the 20 game are much more likely to use metagame considerations in adjusting their play, but i still think it can be better than playing against some of the rock-like regulars in the 10 game and frustratingly trying to squeeze out a few steals here and there
