I felt pretty secure on the flop and chose to slow play it. On the turn, I first saw the possibility of a flush. At first I didn't see it because he bet instead of calling and I put him on a weak 5 or an A Q. Lets say I knew he had the flush: I could have cought a 3 (1 out), Ace (3 outs), a Queen (3 Outs), a Deuce (3 outs), or a 7 (3 outs): For a total of 13 outs, 28.3%. Assuming he couldnt lay it down if I the board paired the river or an ace/3 came, did I have the right odds to call the turn?
