it does hurt bad - but i see this alot- someone bluffs at a stack that is very vulnerable to the bubble and feels committed to it when the 4-bet comes down - usually they lose but once in a while they hit and makes everyone feel that it is rigged - which it isnt - even a 33% chance will hit 3 out of 10 times this is one reason why i like to just go AI at this point of a tourney - blinds are high enough that stealing is profitable with minor risk
