Adjusting post-flop play comes down to exploiting your opponent’s play. Various statistics can help you with this. The article on pre-flop play shows how to determine if a player is tight or loose and passive or aggressive.
On the flop you can continue this analysis. The most important statistics are Agg, CBET and FCB.
The Agg statistics shows how aggressive an opponent is. The more an opponent raises and re-raises, the higher the value for Agg. If an opponent is passive and calls more often, the value for Agg will be low.
Against a very aggressive player you might want to be more deceptive and use techniques as slow-playing and check-raising because it is most likely that if you check, the opponent will bet.
Against a very passive player you want to do your own betting and be aggressive. Make him pay for the turn and river. However, be aware that a tight-passive player could have a strong hand, so you need to have a decent hand yourself if this opponent cannot be bluffed.
CBET and FCB
The CBET statistics shows how often a player makes a continuation bet. A continuation bet is a bet from the opponent who raised pre-flop. If a player has a very high CBET value, it means that he will bet on the flop, regardless of whether the flop improved his hand or not. You might want to re-raise more often against this player.
The FCB statistic shows how often a player will fold to a continuation bet. If a player has a very high value here it means that he will only continue to play if the flop has improved his hand. You might want to raise more often against this opponent, regardless of whether the flop improved your own hand or not. When this opponent decides to play on, you can be quite sure the flop has improved his hand.
