Hi!

Im a noob tring to learn this game. I have two poker questions and maybe some of the more experienced players on this forum would like to help me out

* What does bb mean is it big blind or big bets and whats the different? If you play NL 1/2 how much is bb?

* If you raise 3 dollars preflopp with AJ (big blind is 1) and you are called by one player. If then the flop is K82 and you will like to try buy the pot. What is a reasonable raise in that situation?

Thx in advance!
