[IPSC]

Hand 1:

I think you can let this go on the turn. Villian called your flop raise and now bets into you on the turn. I'd play the flop the same as you did though. A read would be helpful on villian's flop betting standards and idea of what he limps utg.

Hand 2:

Easy fold preflop. The chance that you're dominated is to great. If you had read on MP3 as a loose raiser you could three bet. You do not want to be calling a preflop raise with KQo.

Hand 3:

I'm betting the flop on this hand. Villian may fold fearing that you paired a high card. I'm checking the turn though with the intention of calling a river bet if no flush or straight card falls.
