good starting hand and flop misses

[tomcain]

Hello

This happens so often that I think it is a hole I need to plug. I know it happens often because I see it in PT. Probably 1 or 2 times per 40 hands.

Lets say I have ak,kq, aq or aj. I raise p/f and nobody re-raises. The flop comes down 3,5,7. Everybody checks to me. More often that not, I will bet, representing a high pair. Sometimes everyone folds. But most of the time they don't. Then when the turn comes, I check. Effectively guaranteeing I don't have a pair.

So my question is: Should I even bet on the flop? I am starting to think no.

TIA, tom
