Calculating Implied Odds on the Fly
 

Has anyone come up with an easy calculable rule of thumb for whether to call a draw (or alternatively taking away the odds for calling a draw) in NLHE.

Example:
On a pure probability basis, no reads etc. There's x in the pot, after the flop two players remaining, he bets into you for y, you have a nut flush draw. We'll presume he will bet into you for a similar amount if the flush fails to materialise and that you'll be able to get a similar amount out of him if it does (big assumptions granted).

I need something I can calculate online i.e. You call if the number of outs divided by twenty, times the size of the pot is greater than the size of the raise.

In NL your implied odds is potentially your remaining stack size times the number of players still in the hand.
