(Flush, Ace High)
Small raise from a player on microstakes often means he has a decent hand but doesn't want to play big pot, PPs, broadways and even some garbage hands like 63s. But generally fold is too easy on Zoom so they show up with a good hand.
On this flop I probably fold to a bigger bet. Pool plays rather tight multiway. BTN checks, I assume he doesn't have Kx or set. On the turn BTN bets his Ax, hands like QJ and flushdraw. I have right odds to call. Now on the river I'm not sure whether I should bet or not. V probably doesn't have much two pair. I think with a small bet I don't lose any value.
