"Should Magnus' victories over Fabiano Caruana and Sergey Karjakin count, given that they were decided in rapid tiebreaks rather than classical chess?"
Magnus won both matches but they were decided in rapid tiebreaks rather than classical games in the end. Do you think those victories should be viewed the same way as a match won outright in the classical portion, or does the distinction matter when evaluating his World Championship record? This would go for every other world championship match apart from Magnus #games
