Tough decisions with kickers

[huber117]

heres a major problem i bet most people have, but dont know how to deal with. say your on the button holding A-10o preflop, raise 3xBB, 3 callers. flop is A-9-4 rainbow. BB bets big, MPs fold, BBs bet is large enough to force you all in. what do you do?

the way i figure , with three callers preflop, one must have at least A-x. This situation comes up many times im sure you all know, my point is, what would a real pro do? im not asking for that "it depends" crap. my point is, theres no defense against kicker problems that i know of. straights, flushes, etc are easy to spot, but in poker many situations come up where two players face off, and its the kicker that decides it, but you cant really put someone on the EXACT card- similar to a four-flush turn with 3 ppl seeing it, hero holds queen high. anybody have any advice?
