Daniel Negreanu explains to the table that a raise from 300 to 5000 is not the way the game should be played. Dan's point - It is dumb to bet 10 times the size of the pot when the pot is small. A smart bet is between half the size of the pot and the total size of the pot. To risk $5,000 to win a $500 pot is idiotic. It's like paying $100 for a loaf of bread. It's also like putting $10 in a slot machine when the jackpot is only $1.
In other words - The point is you're not going to coinflip with AK, because they are only going to call a HUGE overbet like that if they have you crushed. Basically you're risking 5,000 to win 300 and in the case where you get called you are going to be very, very, very far behind. You dumb fuck, learn to play n00b.
