1. Looking over my last 60k hands or so, my flop cb on avg (across all positions) is 66%, turn 46.5% and river 58.9%.

I think I could stand to lower my flop cbet a touch, esp IP, so that my ck back + turn calling range is stronger. This is especially true because of all the spots where we should be worried about ppl betting close to "any two", it's probably
a) We raise PF OOP and check the flop (where ppl really don't defend enough)
b) We raise PF IP, ck back turn and face a turn lead (where ppl really don't defend enough or have too weak of a defending range).

I still have a lot of studying to do on my ranges as PFR though. Most of my studying so far has been as the caller of 3bets or cold caller.

2. I think similar to comments above in previous posts. It's probably preferable to c/c hands with decent equity. Pair + FD seems not too bad, or overs + FD or something like 78s on 679 board or something.

I got owned by a reg bvb the other day who c/c Q9 from sb on Q9Thh board, and I overbet the turn (assuming he was capped) and he c/c brick turn and 3h riv he c/c my overbet shove on flush card.

Also we should think about protecting our checking ranges more on boards we are checking often. For example, if we're cbetting some dry A72 board 80% of the time, maybe we don't care that we're exploitable 20% of the time we check. By contrast, if we're cbetting 89Jhh only 40-50% of the time, then it's a lot worse if we're not protecting our checks in that spot when we're checking so often (50-60% of the time).
