reverse implied odds.

with that flop I am betteing because you may have the best hand now and you also have a gutter. sucks if you make two pair on turn cuz then u got a tough decision to make.

if flop came something like A K J and I have A5, I usually check and lead a blank turn because of reverse implied odds. you may be ahead now but you will probably end up putting in a lot of money in later streets when you are outdrawn (unless you play perfect poker).
