Im new at 25NL so only have around 10 hands on Villain - 90/40/2 so i think its safe to assume hes loose over a larger sample. I read a lot about double barelling on here but never really know when to use it. I think he would raise the flop with a decent Q, which is why I bet the turn, to try and push him off a lower pp or something like K10/J10. If im raised on the turn/river i think i have to fold. Any comments about how i played this?
