Thanks a lot for the response.

So what's one of the best poker odds calculator to figure out the below hand I played where I'm trying to figure out the odds that villain has one specific hand after the flop has been played?

So on that hand I lose a large pot in1-2 NL, like 650 as I went all in over villains check raise of 250, he had me covered. He ended up having exactly 77 with a flopped boat, I held AK and didn't improve. Board was Ks, Kd. 7s.

I know I made the right decision but for curiosities sake, and to help me convince my wife I made the right play , I'm trying to figure out on that flop what is the percentage of time that he would have exactly 77?

I know there are software packages out there that would help me figure this out but I'm not sure which they would be.

Any suggestions would be appreciated. Thanks

If his range is unknown the chance of him holding 77 on that flop is 3/47 * 2/46 that's about 0.28%. Keep in mind that nobody check raises ATC though so if you had a range it would really help.

Equilab can show your equity which should be around 90% (against ATC again).
