Lesson 5 - Game theory and math

$$\text{What percentage of cards should be folded in a range} = \frac{Bet}{Pot+Bet}$$

Pot 400, Bet 100

100/500 ⇒ 20% of hands should be folded in your range

Lesson 6 - Cbetting

C-betting with monster draws makes sense because the pot increases and gives chance to win more in the future.

Lesson 7 - check raising

Importance of blockers. Not having the highest card but pocket pair that connected with flop means that opponent might have more likely top pair which makes it easier to value bet. If board is K73, QJ might be a good hand to bluff because it blocks KQ and KJ hands that opponent might have.
