$$$ for custom stat

[jmflu]

I'll ship $5 if someone could make me a quick stat.

For cashgame, I wanted

How often (%) they Check/Fold the River (preferably when heads up)

appreciate it

[WhiteRider]

What would the "opportunity" be? Do you want the percentage of times that they fold after checking the river, or the percentage of times that they check/fold when they have the opportunity to check the river? (I assume the first..)
Do you mean heads up hands, or 2 players seeing the river?
