i ussually like a check raise on a draw if its heads up and the guy isnt a calling station, but it looks like have been calling the wrong odds!
I thought it was 34% so 3 to 1 of making a flush by the river so ive been calling 3 to 1 on the flop and then 3 to 1 on the turn! eg 90 dollar pot he bets 30 i call then, 140 dollar pot on the turn he bets 46 dollars and i call again ect just for an example.

ill get a hand up in the hand anyalsis later on

thanks for the help guys.
