Well generally it depends on the villain. How often does he fold to 3bets in BU/CO, how often does he fight back (4bet, preferably to know what range, there is a stat 4bet range in HM2). Does the villain fold to cbets in 3bet pots? Sometimes it is useful to know whether he fold OOP or IP.
If someone folds 90% to cbets on decent sample and now he called your 3bet, then I would not cbet very often because he is going to have you crushed most of the times. If someone folds to 3bets like 50% and calls your 3bet, I generally check whether this player folds to cbets in 3bet pots. Once you know this you need to think what is the best line to take. If he folds 100% to cbets he can cbet almost all the time and expect to take the pot down. If he has like 30% then cbet only strong hands.
It really depends also on the history you have with the player and whether he is a thinking reg.
But general stats to look after are Fold to 3bet, 4bet/4bet range, fold to cbet 3bet pots, raise flop cbet 3bet pots.
If someone has high percentage of flop raise in 3bet pots and also low fold to 3bet you can expect them to bluff you on the flop very often and you need to learn to take advantage of it as well. If you someone raises flop cbets a lot you don't want to cbet very often your air but rather nutted hands and then let him bluff all the way down. Marginal hands would be better to check/call.
Hope this kinda helps.
