Un-standard AK

Preflop

The table is 4 handed at the moment. Villain is slightly loose quite aggressive player with $350 or so (36/24/3 or something). He seems reasonable postflop. I have $116 and have been playing TAG (about 18 VPIP on this table).

Some people Fold he raises preflop to $4 and I reraise to $12 with A K. He thinks and calls. Ive reraised him a few times before and hes always folded.

Flop

7 3 Q : Pot $24.50

I bet out $14 and he thinks a little and then calls.

Turn : Pot $52.50

7 3 Q K

check/check (I intended to check/call a possible float.)

River : Pot $52.50

7 3 Q K K

check/call?

Standard.
lol jk bet riv for value.
if he pushes then i prob really cry and then call.

What is villain checking behind turn with that beats you?

Don't ever check this river because villain would love to check behind with pair of queens TT/JJ; value bet and get called all day long by those 3 hands.
