Best session yet

Best session I've had since my return to poker. I think that one of my main leaks before was not getting enough value on the river. Anyway once again a short post, but I will post one hand and talk about it. Also my net balance may look a little odd as compared to my last balance, but I transferred $10 to a friend, got $10 in rakeback for January, (Yeah only $10 because I'm still clearing the deposit bonus on FT, and that cuts into your RB), and cleared a $20 bonus.

My main question here is about my river bet here. At first I thought about betting small and "value betting" or so I have learned; just betting an amount that I think their range can call. However, I feel that a huge holding here is a flush, and although the Ace flush will probably raise at NL25, lower flushes will most likely call a bet. For that reason I decided to bet roughly the pot rather than a smaller bet which I would normally have made. However in retrospect I think I should have bet more, possibly even pushed. This is because if he has a flush, he's calling anyway. Even a king will probably make a crying call as well. For that reason I think that I should have bet more.

Anyway, I'm tired, but good session.
