Definition of pb
Pb are the initials of the expression "pot bet". A pot bet is when the equivalent of the size of pot is bet. If we are on a flop and the size of the pot is 10€ and we bet 10€, we make a pot bet (pb). If you play online poker, you will usually see shortened buttons on your table. Typically, the buttons will be 50% pot, 75% pot and pot. If you press 50% for example, the amount will automatically adjust to half the size of pot.
Under what circumstances do we make a pot bet?
The pot bet is not the most common of the bets. Generally, people will bet 50% of the size of the pot or 75% of the size of the pot. Since most people bluff in poker, we want to bet just enough to get the job done, but not too much so that we don't lose too much when we get called. But in what situation will we make a pot bet? Usually when we're strong and there are a lot of draws on the flop. For example, if you have a pair of kings on 8-9-Q with a color print, you might want to do a pot bet to charge for all the prints.
