It is nice to see someone 87 doing so well improving in chess at that age. I didn't just begin I was a "B" rated player when I was 23. I have just started trying to raise my rating with conviction. But it is a slow going struggle. I am focusing learning to play with the Queens pawn openings which I disliked because it seems like it is a slow positional play. So patience is the name of the game at 77.

Good news, but not good enough yet !
Considering that Vishy is ranked #2 in the world at 45, and Korchnoi was 70 when he last competed for the World Championship, it makes me wonder why we haven't seen someone begin playing chess as an adult and become an IM. Has anyone read any good articles on this, especially neuroscience (or other scientific) articles?
The only individual I have known to start playing and sincerely seek to improve as an adult is a fellow I'll call Abe. (Most people I know play and study intermittently, not consistently enough for me to view their progress/lack of progress as indicative of anything.) He learned to play at 28, and played for a few years, earning a rating of 1200, but he quit for almost 25 years. He took chess up again when he retired, and has played tournaments and studied consistently 4 hours per day moving his rating from 1200 to 1950. He's 87, and he may crack expert in the next two years. He's gaining exactly the number of points that I was told was reasonable for 10-20 hrs of study per week for an adult (20-50 rating points per year). I once asked asked a neuroscientist what the deal with this was (i.e., why it is hard to imporve as an adult), and she told me that it is a battle with neurons operating slower and slower with age, etc., versus the speed at which someone can cut new neural path ways, induce (minor) neuron generation, etc.
I haven't known any neuroscientists who study brain activity with respect to chess, so I'm wondering if anyone has found any good articles discussing what's going on with aging and developing chess-playing ability?
