Final Pot: $19.65

No real reads on villain. From his raise preflop and call on the flop I was thinking AQ or KQ, POSSIBLY a flush draw. If he had the AQ/KQ of hearts I would think that he would play it aggressively since most players at this level go nuts for that [censored]

I shoved the turn rather than checking because if I had checked I would have been in a tough spot since I doubt he'll check behind. Also I shoved because if he did indeed have AQ or KQ, I would get him to commit since my shove was a pretty big bet, looked sort of like a bluff.

Should I have played this hand more conservatively? I honestly didn't like my play too much because I was a little scared when I shoved the turn, I was pushing hoping he didn't have the flush, or even the straight (though unlikely he'll call a reraise with KJ, but I gues you never know).
