1. depends extremely on what is "min cash"#1. 4bbs in nor here-nor there. if the closes stack to you in also 4 bb and the next 5bb you CAN justify holding and waing, but of youy have 4bb and the next stack is 10-20-30... you do understand that fom
odds perspective you are not going to bubble some1 out, right? =)
2. depends extremely on what is "min cash"#2. many do not like this argument but what is min cash to you in $$$. lets say you won a satty and now playing you ABI*5min cash would be ~ a deep run in you avrg scheduled MTT. so... hold = good. On the other hand you play 1.1$ hyper and min cash is 1.85$ I am sorry bro but I would not care about that. I repeat myself, many dont like that argument as you should play poker and not care about $/Hr.
3. from push/fold bot perspective I would push 100%. I am pretty sure at you should have pushed something ~10BBs ago LUL. You can safely push K5o from BU for 10bb and be certain that its a good push unless you have some reads on you op you will be called by words aces 100%(fine 99.9) of the time and hands like K5o can not call you
