I'm going to post the hand and the questions and then follow this post up with my own analysis.

Players: 9
Blinds: 400/800/100
Stacks: Hero has 35,000. Villain has 65,000.

Preflop (2100)
Hero is dealt AhQs
1 fold, Hero (UTG+1) raises to 2000, 5 folds, Villain (BTN) raises to 4500, Hero ???

Reads: Villain has been quite active and seems like he's not a fish, but maybe mindlessly aggressive in spots. We have seen him 3bet about 7 times in 6-7 hours and he hasn't shown anything down. Hero should be viewed as competent, not out of line, and maybe on the tighter side due to card deadness.

Questions:

1. What is your play against the opponent described?

2. What % does Villain need to fold to a shove before you prefer shoving over calling or folding?
