10/20 Borgata - KJ flops the nuts, what do to on turn?

[chillrob]

Pretty loose 10/20 game at the Borgata, hero has KdJs and limps in after a few limpers in MP3, 6 see the flop for one bet each.

Flop AQT, with two diamonds (including the ace). One bet to me, I raise, one late position cold caller, original bettor calls.

3 players see the turn, 9d. Early position checks, hero ??
