Ok I often play hands like KQo or KJo from mid/late pos if I can cheaply.

When I hit either the K, Q or J on a (raggy) flop I will usually up the aggro with a feeler bet to see who has the goods, usually about 1/2 - 3/4 pot sized bet.

If I can take the pot right there perfect, If I get re-raised, fine I was probably outgunned and am happy to not lose anymore to this average hand.

What I do have trouble with is when someone just flat calls my raise and then I am again first to act on the turn (assuming 4th street was another rag card)

If I check they bet large, If I fire again they call again.

I've showdowned a few of these hands out of interest and seen a range of hands played from:

- nothing (assuming they thought I was stealing the pot)
- same top pair with Ace kicker
- two weak pairs (guess this cant be helped cause of preflop play)

So my question is:
If you cant take the pot down on the flop, is it time to check-fold?

Theories/advice/stories please!
