A couple of interesting articles...

Here are links to a few articles I found rather interesting. The first one is interstingly enough on pokerbots :) Personally, I hope that the online poker sites are doing all they can to track down any usage of such programs. Although, in non limit games, I'm gonna guess there are really too many variables to make an efficient pokerbot except at very lower buyins where human competition is horrendous.

Are poker ‘bots’ raking online pots?

The second article is again related to artificial intelligence (AI). It is much newer than the previous article and it points out that AI is far from able to compete well in poker against good opponents. The problem is in "incomplete information". In something like chess all possible information is there but in chess you have to "guess" on some of the factors. Take a look.
