Don't look like a stone

Look like a person who has what you represent you have. Seems to work for things other than poker to appear (or try being) sincere rather than robotic.

A ton of poker though is calculation on the fly, which is more like a robot move than a person. Real life has either more or less game theory to it.

Hard to tell sometimes whether that stuff is a hammer in search of a nail or the nail in need of a hammer.

And speaking of poker... This is a good trend back away from the brink of silly laws and prohibitions. I seem to remember that passing that law in the first place cost a 30 year House member in Iowa his seat. From millions that poured in from other states to run against him on THAT issue (online gambling) alone for introducing a little clause as a rider on a "more important" security bill.
