Board 1.  644 Rainbow, Bu vs BB.  PIO check raises virtually all of his 4x on the flop, and as such has ‘no’ check raises on the turn.  We all know that real world Villains love to slow play 4x on this flop, with the intention of check raising any turn.  How do we exploit that?  Mostly by checking back anything that can’t beat a 4 on turn, using very low equity hands for bluffs that have an easy fold to a check raise (and a small size too), and checking any draw that will beat 4x.   On the hand I played where I faced this problem, I had turned the nut flush draw and was forced to fold what was probably about 20% equity while losing my turn bet in the process.

Board 2.  J72 with a flush draw.  Bu vs BB. Bu bets flop, Villain calls. Flush comes on the turn.  PIO ‘never’ donks the turn when the flush draw comes in.  Once again, real life opponents will bet this turn when they have the flush.  Close to 100% of the time among ‘recs’.  Possible exploits:  Fold (duh) unless we can outdraw their ‘obvious’ made flush, and have the right odds/implied odds.  Of course, if they are betting all of their made flushes on the turn, that leaves their checking range way too weak.  We can then bet our entire range.  

Not sure if either of these conclusions are correct.  Hopefully some better players than I will weigh in.
