Pot size bet
Definition of pot size bet
A "pot size bet" is a bet the size of pot. If you're on the flop, the pot is 25€ and your opponent bets 25€, it will be said that he makes a "pot size bet" (bet equal to the size of the jackpot). This bet is not the norm in poker games. Of course, you will see players making pot sizes bets, but most of the time, players will bet 25% pot, 33% pot, 50% pot and 75% pot. These are mostly the bets that are offered as shortcuts when you play poker in your online poker room.
Why is pot size bet rarely the optimal bet?
When playing poker, we want our opponents to make mistakes. To encourage them to make mistakes, we want to give them hard decisions. If a player has a flush draw and I make a "pot size bet", I completely discourage them from running their draw. I give him an easy decision and I encourage him to fold. By betting less, I still make money in the long run if he has a color print and I keep it in my hand. And if I bluff in pot size bet, I lose a lot when I get called. Often a small bet would have done the same job.
