classy play from pobre
tough to even think about laying this down, at what i guess is a low ish buy in.
It is similar to kinboshis situation in that if you give the limp caller a wide ish range at this buy in - bottom set , flush draws , 2 pair etc etc and even J9 and the caller like you said - top pair , 2 pair and flush/straight draw it is one of those scenarios where
you are only around 50% to win. With them both all in by the time the action passes back to you with 30bb i would not say it was to bad or wrong to fold.
Whatever you are comfortable with,chip accumulation or the survive camp both have there merits.
I do not know how far you were from the levels where the antes kick in,but sometimes when i have 30bb+ with the antes soon to kick in,then i"m happy to pass up a 50% edge. [i tend to base some of my decisions on stack-sizes , blinds , structure of the mtt and chip average etc etc]
my tip of the day LongshanksED is for you to explore as many articles and books etc etc on mtt structure/stack sizes and the different strategy"s you can employ.
