whats a redraw?
edit:nevermind found this

Redraw
A way to further improve your hand after hitting a draw is a redraw. For example, if you hold 9s2s (on the big blind of course) and the flop comes JsTs3c, you have a flush draw. If the turn is the 8s, you have made your flush and picked up a straight flush redraw.

do you mean that they might have a hand and even if you hit it might improve their hand to still beat you?
