So, the hand went something like this (dont have the HH here, am at work)

25NL
i'm in the small blind with 24$ stack on a full 9 player table of average stacks
6 people limp (only one folder in mid pos)
i have AJo
i raise to 2$
utg (about 20$ stack) calls and everyone else folds
flop comes 10 7 3 rainbow
i cbet 2$
villain calls
turn comes A
i bet the pot size
villain raises to 2xpot
i call
river brings a blank (no flush/straight possibilities)
i check
villain bets half pot
....

So, the way i saw it:
many limpers, i try to steal by pot raising and i still got a playable (though weak) hand if anybody calls
utg calls and the rest fold
i put him on Ax, paints, or small/medium pair
make my cbet and get called
the A turns and i bet the pot, i get called
at that point i think i maybe beat, i check and he bets half the pot

Now, if he has a small-middle pair, he could be winning (he hit trips) or losing (he has JJ, 99, etc...)
If he has Ax he is most probably losing, unless he paired his kicker
If he has paints, he is losing and bluffing

The thing is i had recently stole some blinds by raising (in late pos) on the limpers

Could it be he's playing back at me?
Does he have a monster?
Is he betting something like K 10 or JJ thinking he's betting for value after my check on the river?
