If the money was enough to make a difference I would (and depending how flush I was with cash at the moment). If we are talking about $20 no, if we are talking a long ass tournament, and the min cash was like $5000, I would seriously consider it depending on my current financial condition.
Ok, some good points here, i can see you calling if that means a shot at being the chip leader, but let's make it more interesting now:
Blinds are 250/500, you are the chip leader with a 20k stack, villain has a stack of 17k rest average between 5k-12k and several below the average, if you get busted, you are not out but you are below the average now, if you win, you pretty much sealed your seat. do you still call?
