We all have been down that line, but i have to agree with u, but there is still a chance depending on how high the flush draw is and how many outs are there, that u may not be able to buy the pot, so that's why i would just bet enough to not lose enough chips just in case the person decided to call, and hurt my stack. Earlier in the day i was playing in a 1dollar tourney on Absolute poker, and i had q/8 off in a bb, and no raise so i checked, the flop was 10/j/k of my suit, and it went raised, reraised, and all in, now i had the person. "the all in" coverd, but I didn't have the orginal reraiser, but i still ended up callin, and luckly hit the royal, so, in conclusion all i have to say is when your betting make sure u don't bet enough to hurt your stack or else u might end up being the person who is really falling for a trap.
