i cap JJ preflop vs a SB 3bet.
so what to do when you dont know what to do?
ask yourself some questions during this hand. for example:
-whats his 3betting range? (thats a question you have to ask yourself before you even choose to call or cap his 3bet preflop)
on the flop:
-which part of his range has you beat, what hands improved, and which ones do you beat?
-weigh on what % of his range has you beat
base your decision on those facts. when you analyze hands like that on your own, use the ps.com equilator or pokerstove and give your opponent ranges based on his stats and your reads, then see for yourself what your equity on a board like that against a 3bet range from a TAG (or whoever) is.
you could try to answer these questions for yourself and maybe you come up with a good idea on how to play this hand?
