In my experience, a min bet is the easiest way to get an aggressive player to put more money in the pot in NL. It looks like a post oak bluff.

This has certainly been true for me at the $20 SnG and $25 NL ring level of play. Strangely enough, it seems that most players would put you on a better hand if you checked than if you bet the minimum.

If you're worried about giving a flush draw a cheap card by min betting, then you should also be worried about giving a flush draw an even cheaper card by checking.

I should add that I think this works for me because I am somewhat aggressive, and will bet at the flop a fair percentage of the time, even if I miss.
