Disagree. Bridge *can* be a much more complex game than poker, if the restrictions on bidding were lifted, but as the games stand, poker is much more complex than bridge. One test that I have for complexity is who would be the winner in a computer vs human WC match. In a bridge contest, I think Zia long ago withdrew his 1M challenge. In poker, only very recently have the computers been good enough to take on the pros 1v1, let alone play at a table with 10 pros. I don't know what other criteria you use to determine complexity, but I think bridge is way more complex also. You can teach someone poker in 5 minutes and within a few hours they could be reasonably competent. You cannot teach someone bridge in 5 minutes, and even if you could, they'd still need a lot more than a few hours to really get it.
