By the way, there is a very interesting tournament going on currently -- TCEC, unofficial computer chess championship [1]. The main intrigue of the tournament is the fight between Stockfish and Komodo. Houdini, dominating engine in the last few years, already lost any chances to go into the superfinal -- two very strong challengers, Komodo and Stockfish, in the last few months were able to eat huge advantage of Houdi…

To make it truly interesting (from the algorithmic point of view), these competitions should be limited to a standard machine with no connectivity. Otherwise it's an arms race.

In TCEC all engines run on the same 2x 8-core Xeon. It's WCCC that allows engines to use arbitrary hardware -- e.g. on WCCC 2013 Jonny run on 2400-core cluster, but lost anyway to Junior that used 24-core Xeon.

Limit holdem has already fallen (see, eg, polaris and sonia --- and even freely available software like neopokerbot is very strong) It appears that NL is close to falling too, if it hasn't already: http://www.pokersnowie.com/

what about Go?

afaik, Go has not yet fallen.

I'm an experienced poker player however I'm an absolute chess novice. Aside from the obvious "just practice" advice, what are the best resources to fall back on in terms of books, videos etc if I wanted to learn the game in significant depth?

I'd highly recommend "My System" by Aron Nimzowitsch. A deep dive into positional play instead of specific tactics

Right now the chess produced is still more interesting than the algorithms themselves. Once we've hit diminishing returns there, it's likely that they'll realign as you've suggested.

Ratings and differences of ratings may not be comparable across time. http://en.wikipedia.org/wiki/Elo_rating_system#Ratings_infla... : "It is commonly believed that, at least at the top level, modern ratings are inflated."

Rating differences at any given point in time are comparable to rating differences at another given point in time. That is, A being 200 points better than B in 2013 means the same thing as C being 200 points better than D in 1963. This is a fundamental underpinning of Arpad Elo's model. It is absolutely true that the Elo model is a relative one and does not guarantee that a given rating number represents the same abi…

Is there a mathematical proof that the Elo ratings have interval properties (so that "Rating differences at any given point in time are comparable to rating differences at another given point in time" is a surely true statement) and not just ordinal properties? I ask, because this is a hot issue in psychology, which I study, and it appears that almost all psychological "measurements" have, at best, merely ordinal properties ("A is smarter than B") and not interval properties ("A is as much smarter than B as B is smarter than C"). Constructing interval measurements properly is HARD, and yet assuming numbers have interval properties when they have only rank-order properties is easy, so I wonder if there is really a rigorous proof on this issue as to chess ratings.

one reason why Poker is becoming the great strategic game for all of the World (or so it seems)

NL,the only popular Texas Holdem variant is far from being solved with 100 big blinds+ (the normal buyin). If that was the case then we would see bots at the higher levels. It might happen one day, but then we will know within days because someone eventually will get too greedy. That said, at micro limits ($10 buy in etc.) there are bots that can make a small profit, and from time to time poker companies ban these and freeze the money. Even Dropbox CEO claims to have made a breakeven bot.

Do you think age has a lot to do in chess?

Well I don't know much about chess, but I've read some chess history off late. I think age should not be an issue. But sometimes people go through rough times. It happens, people don't stay in form and the added pressure of the event makes people more desperate and to act in urgency. Big blunders happen in such situations. This isn't just restricted to chess. In nearly walk of life this happens. I know some very bril…

I'm sorry but you're just in denial. There's no doubt that the peak is in the 30s. Even late 20s it's starting to slow down, it's just that the amount you can learn and experience in the 30s you get further, but once you are in your 40s the decline surpasses it.

I didn't say it was solved, I said that it's nearly as strong as the best humans.

Furthermmore, known bots have been winning at mid-high stakes from at least a few years, and have taken millions from online poker rooms.

Lots of discussion about pokersnowie here: http://www.deucescracked.com/forums/131-Poker-Theory/topics/...

Most of the experts agree that it's very strong.

The Elo rating system is based on the model that a rating difference gives x an expected result as a function of x. Therefore, the Elo ratings "have interval properties". For example, the Elo rating model states that if A's rating is 200 points higher than B's, A will get in average 0.76 points against B.

However, of course the Elo model might not be perfect, and thus a lot of other things contribute into the rating difference of players A and B, not only the expected result of the players playing only against each other.
