10/20 intersting spot with bottom set

[DanK]

ok thanks. I ended up pushing on the turn just cause I was pretty sure he would be going all in on the river no matter what, and I dident want a K or Q to come and get bluffed by 2 pair. Turns out he did have KQ, but I spiked on the river anyhow.

Say you do just call the turn and a K or Q comes on the river, can you fold to an all in. If its some other blank you have to call down dont you?
