Hero in BB with $500
Villain in SB with $450
Folds to Button who opens to $25
Hero in BB 3bets to $100 with AcAs
Js 7s 4s
Effective remaining stack is $350, and a 2/3 pot bet would be $150, or just over 40% of effective...which would be a shove or fold
A 1/2 size pot bet would be ~$115 which would be about 33% of pot...
What is the standard play here, a shove with the Ace high flush draw and over pair?
