Here I have no clue on how to say if my play is good or not.
First I don't really know what my preflop range is because I haven't make my standard play preflop.

This is because CO hes open to 4bb whereas he hasn't done that before so I have take a little more cautious line, but I don't really know whit what I do that.

And I can't analys the flop with Pio because it's a 3 way pot.

So here I have to go by feeling.

CO was 44/13/5 (100 hand)
and BN 29/20/4 (850 hand).
BN has loss at showdown on his 2 turn raise and he x/r more than 10% on each street.
This 2 things tell me he is not only betting and raising with nuts.
And I have one note on him, saying he had raise me turn with TT after a x/x on a flop A high and he had x/x river unimproved.

Bn have probably some five (A5, 55, 65, maybe 75 and 45), some brodway and some card with fd in his preflop calling range.

Do you think he bet often enough the turn with no five hand to make the shove +EV ?
And if yes, do you shove or do you think than x/c is more +EV ?
