Re: Being unpredictable

would you say that the techniques and tricks for online and offline pocker are almost like 2 different games?
with similar rules
or its not as different as that?

The main rules will be the same.

Now, the way of playing has to be different.
In the offline game, bluffing can involve several aspects, such as facial expression and table posture.
In the online game, these aspects no longer apply. Therefore, the only bluff that can be used is the level of betting behavior, and whether or not to go to the game.

yes! totally agree
level of betting and also repetitive behavior or not, even on online poker sometimes you can tell after playing a few tables if the person usually bluffs more or not by the way they bet/fold and frequency

Not that much since it would rather be ending up as a hunch unlike if you do able to see the persons face or in physical on where you can presume out that he is really into something on where these things cant really be determined when you do play online.You can determine things between two.
So its up to someones own perception and observation but we can really tell the diffence.

Even online we can see some tells about what your opponent may have, and everything has to do with patterns, if you see that your opponent takes most of the time he is given to think about his move but then he begins to make faster decisions then you need to wonder why that is? Most likely this has to do with the fact he has a good hand and it is going to be difficult to beat it and he is so sure of himself that he is not afraid of calling everything that you throw at him, obviously this process is easier to do in real life but there is still ways to get out information out of the betting patterns of your opponents.
