It seems that all players abuse all-in. But most pros are usually smart enough not too, but latley it seems they are abusing it too.

I just can't figure how risking a 2-4 Million Dollar stack with a semi-great hand to win maybe 300k in the pot is a good play.

Just the slite chance they will stumble upon a well concealed monster seems to be enough to make this play be a long run loser.

Especially when you are in the later part of a tournement and not only is your stack, but your total tournement life is at stake.

Can someone justify this play, or am I correct that it is terrible?
