-what position 4 bet shoves? did you 3x his 4 bb? you should try adding a bit more info, stats as well would be useful
does the person who shoves have everyone covered? if he is short and early position jus called and we have enough chips, by this point the odds are there so you could call to see a flop
if the player behind you is 4 bet shoving a stack thats close to you and EP calls your most likely up against two PP and just fold because your behind and its early so why take the risk
oui?
hope it helped, from the info you gave im pretty sure its standard fold because your behind and you have no fold equity anymore
if the two players r donk idiots then probably get it all in
