$3/$5 - 9 handed
MP / lag ($400) opens $25
BTN / tag ($1500) 3bet to $60
Hero SB ($500) AQo 4bet to $170

I was thinking Btn can 3 bet iso the lag player IP pretty wide here with a lot of suited broadways and TT+. How is my sizing? Good play or bad play? I tried to size it in a way where, i can fold to a 5 bet jam without being committed, but size up enough where btn is not calling with all of his hands.
