This isnt my hand but a friends hand we have been discussing. Thought Id post it here for further opinion. This is stars 50 rebuy 16 left, I think at this point hero and villain are both top 3 in chips. Last hand hero won a big pot and is now on the button, villian in BB has been aggressive and has shown he can 3 bet light........
9-max Seat #5 is the button
Seat 1: (110775 in chips)
Seat 2: (39752 in chips)
Seat 3: (74542 in chips)
Seat 5: HERO (195263 in chips)
Seat 6: (149888 in chips) out of hand (moved from another table into small blind)
Seat 7: (38244 in chips)
Seat 8: VILLAIN (248597 in chips)
Seat 9: (128944 in chips)
Seat 1: posts the ante 300
Seat 2: posts the ante 300
Seat 3: posts the ante 300
HERO: posts the ante 300
Seat 7: posts the ante 300
Villain: posts the ante 300
Seat 9: posts the ante 300
Seat 7: posts small blind 1500
VILLAIN: posts big blind 3000
*** HOLE CARDS ***
Dealt to HERO [As

]
FOLDED TO HERO
HERO: raises 4500 to 7500
SB: folds
VILLAIN: raises 16350 to 23850
HERO: raises 42150 to 66000
VILLAIN: raises 182297 to 248297 and is all-in
Based on the info given, would like to know what you think of the Hero's 4bet and 4 bet amount. And then when the villain 5 bet shoves, what range do we have him on here and do we call or fold?
Would anyone play the hand any differently until this point?
Thanks
