Hand 68: In this hand I was dealt As Td (2,790) in the small blind. Supadphat (1,800) shoved from UTG+1 and I shoved. He showed 9c 9d and the board came Ks Tc 8c 4d Qd and I was up to 5,090 chips.

Commentary: Easy shove. The villain pushed 3BBs, and we have a very good hand in ATo. He has to be shoving tighter than 55+,A9o+,A7s+,KJo+,KTs+,QJs for this to be a fold, and he is DEFINITELY shoving wider than that range. We were lucky to win this flip, and I was very surprised to see him turn up a real hand, rather than a Q9o type hand.

How do you know the hand ranges in these examples?
