UTG+1 is a world-class pro, plays extremely well. He had been playing very tight in the 50 or so hands we had been at this table, but this is probably more of a function of his hand distribution than anything else. Am not familiar with BB but I assume he is a competent reg.

As they say, there is no right way to play Jacks (or there's 3 ways to play Jacks, and they're all wrong). In any case, the reason I did not 3bet pre was because of the UTG+1's tightness thus far, and I felt JJ was too strong to fold to a 4bet, and I would not be doing well against his range if we went 5-bets. The downside to playing the hand in such a manner is the tendency to playing a hand this strong to effectively show down, and also laying the BB a very strong price to peel. Other problem is now I am theoretically "underrepped" (whatever that even means), and if I flat once UTG+1 folds I might get outplayed and fold the best hand quite often depending on the BB's squeezing frequencies.

My questions are as follows:
1) what do we prefer given reads initially, 3bet or flat, and why?
2) once we flat and are squeezed and UTG+1 folds, what line do we prefer taking, and why?

Felt like this hand could have gone a lot of different ways. Thanks a lot,
David
