However, the evidence imho suggests that to play chess at the highest level is more difficult than bridge. If you are not a high class chess player by age 13, say, then you have almost no chance whatsoever of becoming a GM. The brain actually reprograms itself to use the face-recognition part as a chess pattern recognition center. This should make the decision on whether to concentrate on chess or bridge very simple for anyone looking to reach a high level. In bridge there are examples of players that have reached a world class level having started playing much later in years. I do not have enough knowledge to compare either with Go. However, anyone who has played MtG will know that the suggestion of its complexity being in the same ball-park is laughable. I suspect it was made tongue-in-cheek to make some point or other.
Why is this evidence of playing chess at the highest level being more difficult than bridge? I submit that extremely young people are not capable of playing bridge because their brains are not developed enough at things that are necessary to be a top bridge player. Bidding judgement, taking inference from the opponents actions, etc are too hard for someone that young. You also need more experience for bridge, because you see so many different situations/patterns than you do in chess, and it's hard to get enough useful experience when you are that young.
I believe that your processing speed/abilities are probably going to be best as a late teen. I could definitely crunch the numbers faster and better, and think clearer when I was younger. That kind of processing ability being at or near its height is much more important in chess than bridge.
Bob Hamman once told me he thought a bridge players peak is probably around 40. This is the best combination of acquiring the right amount of judgement/experience while also having high processing abilities, as well as physical ability (being able to concentrate for a long time). It's possible that it's younger because younger players can get more experience now playing online faster, but I'd be surprised if it was earlier than your earlier 30s. I'm sure it's younger in chess because the price you pay in your processing ability is more costly in chess for the trade offs.
Of course the counter argument to this is we've never seen what young people can really do, because far more young people dedicate themselves to chess than bridge, by a large amount. I could be wrong, but I believe that while very young people would be capable of playing the cards at an elite level, they would be incapable of bidding at an extremely high level. Bidding is just so much more about things that a more mature brain is going to be better at, on top of the enormous amount of knowledge and experience necessary.
Also, I am biased. I will immodestly say (not to brag) that I was very likely one of the best 2 13 year old players ever. And again, I'm sure this is because I was one of the few people who got heavily into it so young, it's easy to beat a small pool of people. My cardplay then was very good, and my bidding was not. I did not focus on bridge full time though, I went to school, but I do believe no matter what that I was not capable of being an elite bidder at that level. My cardplay was not elite, just quite good, but I believe that had I been a hardcore dedicated person like some of the chess people, I would have been able to play my cards at a near elite level. Still, I'm not sure if I would have been able to process all possible inference well enough. The parts of cardplay that are like chess though, definitely a kid could be great at that, like solving double dummy problems, endgames, etc.
My main point was that both games are very hard though, and despite both games having dedicated people, people suck at both games. I find it hard to believe that this is debatable. I never meant to imply that only in bridge did everyone suck as far as games go.
Comparing incomplete information games to perfect information games is really hard, and depending on your priorities you can reasonably judge either game as harder obv, it's subjective.
