Fischer redivivus

The Berlin qualifying tournament to determine the challenger to world champion Magnus Carlsen has ended in victory for the American grandmaster and Olympiad gold medallist Fabiano Caruana. Caruana will be the first homegrown American contender since the days of Bobby Fischer in 1972. The world championship match will take place in November in London. This is the first time it will have been held in London since 2000. (Before that, they were held there in 1986 and 1993.)
 
It is clear that mental preparation will form a key part of Carlsen’s approach to the London shootout. I have a theory that his style is based on that of Emanuel Lasker, world champion from 1894 to 1921, whose forte was to keep the position in flux, either with a slight advantage or even disadvantage, so long as a draw was not on the horizon. Eventually, his less skilled opposition would crack and Lasker would pounce.
