think poker is more difficult than Go and of  course chess.
I have only studied poker AI basics and coded game rules, learned play slightly winning net poker. But however dare to say my opinion that I totally disagree. Sounds like somekind of poker hype that it is as tough problem than Go game AI 19*19 table. It is offcourse very complex interaction problem but
my opinion is that it is still lot of easier problem.

It is maybe even possible that it can't be proven and that theory you are right, because poker can be iterated forever and that in theory propably there is _no_ best strategy. I see it very same/similar thing than in super simple iterated prisoners dilemma problem. There just is no best strategy, any strategy has some other dominating strategy, so I have understanded it. But there is very good strategies, every bet when you but your money in table you play even stronger(bluff), play normally or slow play present weaker hand than you actually have. That thing iterated, remembering what opponents have done earlier (like in prisoners dilemma) it is tough problem, but saying it harder than go game is not true at least in practise.

In practise I see it so that computers have advantage in poker other things than this complex interaction, where advantage is in humans. As computers can actually calculate odds and propabilities exactly, that advantage is maybe slight, but something which similar don't exist in go-game.

But yep just started poker AI in my project http://sourceforge.net/projects/narugo, coded there SimpleActionGenerator, in estimated couple years work it is gonna plays better poker than starter player :|

So imho if somebody states that poker is harder AI problem than go-game, it sounds poker hype.

This is a remarkable result. I think poker is more difficult than Go and of course chess. My hypothesis (its just a hypothesis) for the success is. There is someone - Dave Billings - who worked for many years very consequently on the topic. And he is able to motivate a lot of other good people to go along with him. And he gets probably also a lot of support from his boss, J.Schaeffer. And of course, there is some prospect to win fame and money. The conditions for solving a problem are always at least as important than the problem itself. Maybe are the conditions in Poker better than in Go. As said above, I think the problem is in Poker harder. They have of course not solved the whole problem. Heads-Up limit Hold'Em is the - for computers - easiest game. But its nevertheless remarkable that they are on-par with the Poker-GMs.
