Fun hand reading test

Everyone at table is fishy except for the BB. BB is solid.

2 limpers, I raise with Ks Jd from the button, BB calls, limpers call.

Flop: 7s 9d Tc
BB bets, all call.

Turn: Qc
BB bets, 2 calls, I raise, BB 3bets, 2 calls, I cap, all call.

River: 4c
BB bets, 2 folds, I raise, BB 3 bets, I call.

What was his hand?
