He isn't betting a king on the flop. He's betting a T, or another pair, maybe something like 66. There's a 95% probability you won't hear from a king until the turn.

The problem with the straight is that it's a bit tainted with the paired board, so you can't give yourself full odds. Couple that with the fact you won't know where you stand until the turn, and this is a quicksand hand.

I'd probably call the flop and unless I flopped something amazing (the jack, or maybe an Ace, but I don't like queens) fold on the turn.

Edit: Was in the middle of posting and got interrupted.... I definitely agree with those that say fold, and you probably should. But it is a big pot... I would tread carefully, especially on the turn which is where I expect the big fireworks to take place.
