I've found that simply looking for tables with a high see flop % and high average pot sizes just isn't working. There are so many short stacks at tables, and they either don't pay you off or disappear and are replaced by tight players as soon as you sit down. So my new strategy is to look for the following, in order.

1. Full stacks

Ideally everyone at the table would have more than a full stack, but if there are one or two players with short stacks and the rest with full stacks or 4/5 of a stack, that will do. If there are 4 or more short stacks I will avoid the table, even if the other stats are great.

2. High average pot

If I'm happy with the stack sizes, I'll check the average pot size. I'm looking for more than 25bb, but the higher the better. If it's high enough, I'll sign up.

3. High see flop %

This is the least important stat. The higher the better, but if it's 33% and the table gets good marks on points 1 and 2, I'll sign up. If the average pot size is high it usually means there's enough action at the table to get good hands paid off.

Of course, once I'm at the table if I find I don't like either the table or the seat I leave (hopefully). This should always be the case though. I've been doing it this way for a couple of weeks now and it's been much more successful than just looking for high flop and pot sizes.

I play $25NL at PokerRoom, where most see flop % are between 32% and 38%, and I (try to) play TAG.
