1 shove unless, for some reason, BB is fully aware that you will push with any 2. To hell with it, even if he is.

2+3 If I do find myself here I'd probably pass both of these. You have just enough to still (barely) make people pass after going through one more set of blinds. I tend to shove super-light in LP with this kind of stack though (see 1) which is why I don't find myself here all that often. If it matters though, 3 is a better (less bad) spot than 2.

4 Gut feel is probably call. Stack is now so low that getting it in behind someone else's raise might be your best bet, especially with antes chipping you down further with every hand. I don't much like the raiser being EP (would insta call an MP raiser) but by this point beggars can't be choosers.

Edit : by the way, in 4 call, do not put the last 80 in. DUCY ?
