Tells
Here are a few betting patterns and what they might represent.
The check raise events for pocket pairs and flush / straight represent making their hand on the turn. Also note that the player may just bet rather than check raise.
A check raise typically signifies an opponent slowplaying their hand or an opponent on a draw trying to take control of the hand. It’s important to know your opponent so you can draw a distinction between which of the two categories they fall into.
Thanks to the buttons online poker provides its players, tells can be determined rather easily. There are several buttons including check, bet minimum, bet any, call minimum, call any. There is also the Post and Fold / Sit Out button. If a player is sitting out and your poker provider allows he/she to still be in a pot that no one has raised make sure you bet to get him/her out of the hand, especially if it’s just you and the big blind post and folder in the hand.
Note. These are generalizations and will not apply to every person or every instance. The best way to get a read on a player is to watch them and pick up on subtle differences in their actions while NOT in the hand with them. It is harder to pick up on these actions and play at the same time.
