flops you want with a pocket pair...

[cferejohn]

Does anyone know of a piece of software that can let you calculate odds of specific flop conditions? For example, if you help pockets 9's, it would be useful to know the approximate chance that you will get a 'good' flop (i.e. a 9 or no overcards). Anything out there that does anything like this, or do I need to dust off my math books and remember how to calculate somewhat complex probabilities?
