abandon your search for tells online because they
Probably the most important tells stem from the speed
with which one bets, checks, or calls. You should
keep your own betting speed patterns random and pay
close attention to your opponents. Someone who checks
like lightning has probably preattention the "check-fold"
button, a sure sign of weakness that can be exploited
on the next betting round. Similarly, if someone re-re-raises
in an instant, he has probably selected the "raise
any" button, a reasonably sure sign of a strong
hand rather than a bluff.
For this reason, even though the pre-select buttons
do speed up on the online game, you are better off
avoiding their use except when you are planning to
fold. Even then, you should not use the buttons if
you are in the last three positions because if everyone
has folded to you, it's possible that you may want
to try a steal raise with a hand you weren't planning
on playing. Such efforts are usually wasted in low
stakes "no hold'em" games, but when the
stakes get a bit higher, it is possible to steal the
blinds every once in a while.
