As a chess player, Alexander Alekhine (pictured) was brilliant, but his biography contains a number of dark spots. In particular, his proximity to the Nazis has damaged the reputation of the fourth world champion. The Swiss historian and chess player Dr. Christian Rohrer wanted to find out how and to what extent Alekhine supported the Nazis, and he published his findings in an online article titled <a href="https://elib.uni-stuttgart.de/bitstream/11682/11576/1/2021_Rohrer_Alekhine.pdf">"World chess champion and favourite of Hans Frank?: assessing Alexander Alekhine’s closeness to the National Socialist regime"</a>. Detailed, fascinating and well worth reading.
