I played the NST main event this past Sat,and I've been thinking about this a ton. Basically I feel like I had quite a few great spots to make a play by 4betting or 4bet shoving. In the later stages of the tourney the better players where relentlessly 3betting the weaker ones. I felt like most of the times these spots came i really didnt have the correct stack size to make the play and just folded. I've mainly played small field tourneys and SnG's, So i haven't really seen a ton of these spots. Soooo the questions i have are
1.) When do you look to 4bet or 4bet shove?
2.) What do you consider the perfect 4bet shove stack size?
