I smile at players who call their entire stack on a coin flip early on in a tourney whilst still deep stacked. I"m always happy to shove my chips in knowing that if called I will be in a coin flip situiation, but only if I"m the raiser.... that way I have the edge over the odds..... the opponent may fold to the raise, and if he calls, I may win the race - that means I have two chances of winning the hand, where the caller only has one chance and that chance is only 50/50.
