LATE SNG 4 HANDED ALL IN OR FOLD SITUATION PLEASE ADVISE.

[lilkunta2]

this is one of my trouble spots. i don't know whether i should fold this hand or make a move to try to pick up some chips. the big thing here is that i am shortstacked and will be blinded to death soon, so i moved all in as to take the blinds without contention (hopefully), but got 2 callers and ended up winning.

is this a straight forward fold,,, and wait to see if something better comes??? or is this a clear cut all in???

how do you know?

please help
