Tells

In addition to betting patterns, how often your opponent bets, how long it takes to make a bet, there are other signs that may betray the strength or weakness of the opponent’s hand.
Rapid/instant check
If the check is given instant, most probably your opponent tick the check / fold box .If is not instant, but is given very quickly, however, it can mean the same thing: that the opponent has a weak hand that would throw it on a bet.
It is true, some players prefer to give the check when they caught a monster, but they usually think for the price of a few seconds.
Join the game with an irregular amount
This refer to a player who enter the game with an amount like $ 57.43. Almost certainly, those are all his money that he have in his account .How you can use this in your advantage?
The player will adopt a style of play either loose or aggressive, hoping to double very fast .This is the player that you want to isolate and pull him into the pot. When you feel that you have a good hand or positional advantage, put pressure on players Depending on the type of the player , he will either not make a bluff, folding if being in difficulty or he will bluff with all chips when the pot is bigger or if you can full him with a check ..This player wants to double his money quickly and he will play somewhat the “all or nothing”.

All in over bet on the river
This is also called “bad move”. If your opponent has check on the flop and the turn with a monster, hoping that you will bet then he will pay or raise. If you gave the same check on the river, your opponent will try to redeem his mistakes with an all-in, hoping that you will believe it’s a bluff. It is illogical for an adversary to make check on the flop, the turn and the river to put all-in. Whatever it is, you do not pay unless you have a strong hand. It is possible to have completed a draw on the river and even if it would be completed, he would have played differently .Probably he still has a great hand from the flop , which however he played it in a wrong way.
