That's what confused me.. if he had AK or or KQ he checked TPGK/TK.. so I assume he missed. And being it's 5NL he could've had K rag and flopped 2 pair. Most people won't slowplay that in the event of getting sucked out on. If he had JJ or QQ I could see a check but c/c the flop and turn and auto shove the river tells me he didn't have it. By him check calling me down, I thought he was going for a suckout somewhere.
