we have 12bb here so its an easy call.
out of interest how many bigs are people's limits for calling here vs an unknown? people will still shove in these blind on blind spots up to 20-25 effective bigs sometimes and those decisions are obviously tougher.
It's not the bb's that matter so much, just how it affects their range. Most people will jam tighter 20bb effective compared to 12bb so you'd adjust your calling range accordingly.
