First I'm a No-Limit player diversifying into Limit, where I'm inexperienced.

A while ago I thought that nut flush draws and suited connectors had more value in Limit and I should play more of them in Limit than No Limit. But now I'm rethinking that idea.

I wouldn't bet/call made hands confidently from the likes of A4s and JTs unless it was a non-bottom two pair, Full House, flush, or straight. Statistically, the chances of a implied odds hand making one of those good hands by the river is not higher than 5%.

Which means that in order for making that preflop call be profitable, the pot has to be, on average, greater than 20 times the Big Blind.

Unfortunately, in my "limit"ed experience that does not seem to be the case. The average pot is less than 20 times the Big Blind.

Does that mean that implied odds hands are -EV in limit holdem?

If I can't play those hands, what CAN I play besides PP and high suited connectors?
