This is a hand I read about I think some will be surprised with.
This is a major (10k) tourney - you will be the author in this.
Still early, blinds are 100/200 and no ante yet.
Your stack is 10,200 after posting the BB. UTG called the blind, this player raises with good hands and calls with weak hands. Also, his hand motion indicated weakness.
This lead to a string of limpers, and it makes to you unraised with 1300 in the pot.
You see

and use this show of weakness to pick up the pot with a raise to $2k (10xBB, pretty strong raise eh?).
It folds to the button who pushes all-in, and has you covered.
This player had moved all-in in spots where he could have been bluffing and never had to show a hand, also, you observed his player preparing to muck his hand until he saw everyone folding ahead of him.
How do you play this from here?

This is from Dan Harrington's book. Dan put the guy on a low pair, A-x, or a small pair, even a complete bluff He figured a high pair would have raised already. He figured he was getting the right odds and called. The guy had 76o the flop was 7 5 4 but Dan rivered a K.
