Using Check Boxes/Auto Plays

If you have been to any of the online poker rooms, you will notice that they make use of check boxes such as "fold" "raise any", or "call any".  You can tell when a player has used a check box, because his action comes within the blink of an eye of the player before him.

You can use this to your advantage.  When a player has checked "raise any" it should be obvious that he has a strong hand.  If a player uses the check box to "check" then you can probably surmise that his hand is weak.

If a player uses the check box to "call any", then maybe we can assume that he has a draw hand that he has not completed, but is definitely not ready to fold.
 

While these are not 100% accurate, the observant player can over time, begin to draw conclusions and make assumptions based on an opponent’s use of the check boxes.
 

The fact that a player feels strongly enough about a hand to make a decision before even seeing the actions of the players before him, should be a "tell" as to what that player is holding.

You should not be using check boxes and auto plays yourself for obvious reasons.
