In casino poker card games where there is a long pause, followed by a raise, at www.casino.com this has to be the keystone tell of most online casino poker players. The paradox is that by using this tell, they are really giving off their own strategy. The entire logic following this play screams strength, because casino poker stars generally only do it when there is a big possible hand on the poker table, like a flush or straight. You bet, your opponent poker player pauses for about 10-15 seconds and then raises you.
Sometimes, a casino poker player rightfully thinks you’re bluffing the river or whatsoever so he’s raising you back, but most of the time he’s got a big hand.  Automatic raise occasionally used by maniacs and bluffers, most of the time it’s used by a poker player who is so sure of his hand that he is ready to bet or raise in spite of the action. This generally means that you desire to tread cautiously and consider folding or check-calling this down. It should always raise a big warning sign at the very least.
