So this is from my home game. $10 buy-in, i have about $20, my twin brother who is good has about $25. Ben Stone has about $20. I get AQs clubs on the button. the table is relatively lag. Twin who is a solid player raises 5x BB from UTG+1 (tables 8 handed), it's his standard raise. Stone calls in MP. I call on the button. The pot is now $3.30 (low stakes play, blinds .10, .20) The flop comes 10 8 3 two clubs. Twin bets $1, Stone calls. Me? I have no idea what to do here. Stone is very loose so he could easily have nothing here, probably just a draw, he'd almost have to raise here with a hand. But what can I make of the $1 bet? it doesn't make sense to me. I don't put him on AA because he limps it on our aggro table. I don't have any hand to put him on...

My question is what do you put him on and how do you play this?
