You can get the new version of PT4
here.
I will be putting out a new version of my HUD as soon as I've had a chance to put it together. Things have been unfortunately busy enough that I haven't yet had the chance - especially since I want to really take advantage of the power that PT4 has.
In your particular example, if we have the stone cold nuts you want to look at 3 stats:
Fold to Flop Donk, CBet Flop and Fold to Raise After CBet Flop.
I'd actually look first at Fold to Raise After CBet Flop - if that is low then you basically get a bet and a raise out of this guy if he decides to cbet. If Fold to F Donk is less than CBet Flop it's not worth it to donk - you average getting a bet more if you let him hang himself.
Some numbers might help:
Say he folds to F Donk 70% and CBets 40% (since you wanted someone who cbets rarely). In this case if you donk 30% of the time he calls. If you check he cbets 40% of the time - if the bets are the same size, letting him cbet is clearly better (40 > 30!). If it's at all close then look at fold to raise after cbet flop - that's the likelihood of getting a second bet right now (and bloating the pot making it easier to get it in).
I hope that helps!
