Looking at it , I think i should have raised a lot bigger on the turn, but is there any value to be had betting this river?His calling range pre i feel could have suited connectors that also hit the flush , but would they call a bet with a double paired board and he could also have quite a lot of Tx in his range , not sure that theres many 3's in his range except maybe A3 K3.Could possibly get better flushs to fold but I felt that a bet would just fold out worse and get called by better.
