it must really hurt losing with quads... never happen to me..
but no way someone would anytime fold quads.. you had 2nd hand on that board.. the only hand that could beat you was KK - and he had it..
but i saw a more interesting situation on
titan, in one mtt tourney, on my table.. i was like WOW - is that possible? .. i don't know if i wrote it somewhere, i forgot to capture this.. this was a really awesome ..
delaer, sb and bb... everyone folded.. dealer raised one BB and got called from both.. flop was

.. delaer betted minimum got called from both.. turn was

, river was

... all three players moved at the end of showdown..
i don't really remember if ACE was on river or on turn, but it doesn't matter
the point is.. bb wons that pot.. but: delaer shows ..

, SB shows
BB had

.. he crashed two quads with STR8 flush.. i was really shocked..
what is the point here? can anyone folded his hand here? does delaer played it good with AA on button - should he raise more?! did anyone played bad on flop.. i mean - when you have ACE FULL OF FOURS, and 4 OF A KIND on a flop, you're 99% sure that you have nuts till the showdown and you're tring to trap someone into that pot! i really don't have an answer, but i think sometimes, you can't win even with monster hands..
