10/20 limit - totally lost in the Wynn mixed game

[Glurfle]

Played in the 10/20 mixed game at the Wynn yesterday for kicks. I don't really know how to play O/8, so even basic comments would be appreciated. Please use simple words that even a hold'em player can understand [img]/images/graemlins/wink.gif[/img] Game is 5-handed and just started, UTG sounds British and seemed happy to have 0/8 in the rotation, BB is brand new but seems to be a regular at the mixed game. This is our first hand of O/8, so no real idea how any of them play.

Dead SB this hand, UTG raises, 1 fold, I call on the button with A[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/club.gif[/img]3[img]/images/graemlins/club.gif[/img]8[img]/images/graemlins/diamond.gif[/img], BB calls.

Flop A[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/heart.gif[/img]. UTG bets, I raise, BB calls, UTG 3-bets, I call, BB calls.

Turn 7[img]/images/graemlins/club.gif[/img]. UTG bets, I raise, BB calls, UTG calls.

Thanks for any advice.
