Lasker-Chigorin, Hastings 1895

Some days ago, we presented the tough and complex battle that ensued between Emanuel Lasker and Mikhail Ivanovich Chigorin. In a semi-endgame the young German world champion held the pair of bishops, but it was the Russian forefighter with the pair of knights who emerged victorious in the end. The game has been the subject of controversy for 130 years, so we asked readers five questions about critical positions to shed some more light on it.
