These responses are so results oriented it's rediculous. Why oh why would you raise to blast everyone out of the pot when you have the nuts? The original preflop raiser also folded, so it's unlikely anyone has pocket pair better than 99. The chances of someone hitting running runner to win is what, 2%? When you flop a monster, you want to milk your opponents for every penny they have. Check/calling on the flop is required so your opponenets can catch up, which will hopefully result in getting their entire stack.

In any case, I would have at least bet a small amount on the river. Maybe $15, just under 1/3rd of the pot. When you check, it looks like you don't have the king, which you don't. But by checking you also don't know if your opponenet has the king. He could have the 5, and suspects you don't have the king, so he goes all-in. By betting, if he raises, you can be more sure of where you stand.
