Economist Ken Rogoff: Trump is a street chess player.
Trump is a "café chess player," he said. "This is the kind of person you might encounter at Washington Square Park, quite skilled but hasn't really systematically studied textbook knowledge. They can win against weaker opponents with aggressive attacks; but when facing stronger players, this style of attack tends to expose vulnerabilities and can be countered and defeated by the opponent."
In addition, he mentioned that another characteristic of café chess players is that if you're not careful, they will try to secretly take back their moves.
