Though
poker tells in live poker could be very helpful for those who can spot them, they are still could be very deceptive since they are not based on any exact science, let alone the "Reverse Psychology" often used by experienced players...
We can't try to go through all of them here, there are so many, but I'll mention a few:
-- Be very cautious if an opponent eyes your chips before making a bet, that's usually a strength sign.
-- A sign of weakness is when your opponent looks you straight in the eyes and bets in an intimidating manner.
-- When a quiet player starts talking all of a sudden, he's more likely holding a strong hand (And vice-versa).
-- Another sign of strength is when a player looks away from the flop as if it does not please him.
-- A big bet on the river followed by a sip of water is very likely a bluff.
-- The shaking hand when betting is also a sign of strength.
In
online poker, there are only a couple of useful hints one could exploit. The most known are:
-- The timing, though it's very tricky and varies from a player to another depending on their level and experience. You really need to be carefully observing your opponents all the time to be able to decide when they take a certain time to act and when they take more or less and why.
-- And then the famous "Betting Pattern" but I think everyone here knows about it.
-- There are also a few behaviors that indicate recreational players like limping, betting the minimum, showing their hands and buying-in for the minimum in cash games.
