3) When you are playing more tables, play tighter early. A lot of your edge limping with speculative hands is diminished if you dont have a direct feel for players in your game.

I've recently started playing four at a time. So I'm wondering, what other changes should one make from their standard one at a time SNG strategy? I'd especially appreciate any input from stupidsucker and others who have experience playing 4 or more tables at once.

Are there previous threads on this topic?
