It`s not about the complication of the game - of course chess is more
complicated than poker even from psychological point of view - but it`s
about money involved : even when they are smaller sums they are more
visible. The money is usually on the table and every kibitz is excited even
if poker players play for small sums. Poker is like one of those
brainwashing TV competitions when one wins visible money.

I don't think that matters much. There's no visible money in
football, for example.
