JTo in the BB

[Boolean]

This is my first table, first deposit since September. I played very sloppy and I'm looking to correct that soon. I feel my first big mistake I made was calling the flop. Getting 5-1 with two weak offsuit cards, I should've folded.

This was the first orbit so I had no real reads on any player at this point other than they're very loose.

Flop: (10 SB) Q[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(5 players)</font>

At this point I felt the pot was rather big, laying me 11:1, and I have middle pair with a back-door straight draw. There are no flush draws on the board, so I give myself 6.5 outs total. Should I discount this on the off chance I'm up against QQ or JJ?

I'm probably behind here, but with my raise, I force others to call 2-cold, and I can buy a free-card on the turn.

The pot is laying me 10:1 and I have an open-ended straight draw as well as outs to 2-pair or better. I call with the intention of folding UI on the river.

Final Pot: 14 BB
