[1]A nitty Tagg has called PF. I must assume that he at least matches my opening range from excercise 1.(22+,AJo+,ATs+, 67s+, and occasionally weaker hands)
Since I cbet virtually all of these hands his raise on the flop must be treated with respect.
Not actually knowing he has KQ in this example I would only continue with 66, 77, TT+. Ax and draws would have to fold.(Probably about 80% of my cbet range)
Folding 4/5 means that my cbet is indeed exploitable here.

[2]If he raises when I check the turn I feel I'm in a similar situation.

[3]The purpose of my flop cbetting range was to exploit his tendency to fold if he didn't hit something on the flop.
However this exercise has shown that my tactics can easily be exploited in return and would have to change in the face of repeated aggression.

On a personal note I found it interesting that these exercises caused me to think about what I SHOULD do, not necessarily what I HAVE done in the past. Is this a sign of something being learned?
