In a cash game, very few players bluff 3-bet, and bad player virtually never. You made an excellent fold of a good but probably 2nd best hand.

Now, this is a tournament, so there may be some different dynamics at play. Was he short-stacked and giving up? Even in a limit game, short-stacks sometimes just "rack off", tossing he last of their money in the pot in a spot they know is -EV, because they are annoyed they are losing and just don't care.

This is much more common on the early streets than the river though. I think your fold was the right move.

good luck.
