depends brotha, like others have said it depends on if your willing to bust..also depends on your eff stacks, depends on your opponnents shoving range..and at lower stakes shove ranges are usually pretty wide so id usually call with 88+..prob even 66'+...depens on your position too and how many chippies players to your left have..so you gotta make the decision to either flat or iso yam
i made such a gooood and baaaad fold at a live tourney about 2 weeks ago(my last live tourney in the states for a while



)...first one i had KK's and i think ~3x pre, had a flatter, and another dude 3bet jam for my stack...i literally think for 1 minute(which is too long for those old dudes at a live table) show the dude next to me and say oh well..it was still like the 2nd level and i really just wanted to keep playing..and the guy next to me is like "well damn ill take it!!!" i said go ahead hes got AA's...cause nobody, especially the old dudes there dont rip it in like that without AA's 3 ways that early in a tourny..then this other super salty dude that i rivered twice said "wow i dont think im good enough to fold that"...the 3bet jam guy showed his AAs..pat my self on the back and actually cashed that tourny for second to last (5th place, sigh)
second hand: we're down to final 2 and this lady jams..i have 66..i think for about 30s cause i had a limper behind and i feel like i had the bigger stack out of the 3 but not by much at all..those tourneys get soooo deep..i ended up folding the best hand..that hand would have probably put me at at least 3rd when i hit the final table if i just flatted..but i couldnt make a decision if i wanted to just call or iso..
the funny thing is, live and online are 2 different beasts..online i pretty much snap call with the KK's, and the 66's id probably flat after about 3sec tank lol..
