15-year-old IM Aarav Dengla draws a few comparisons between the World Championship that is starting today and the one which took place over half a century ago. What are the obvious similarities that come to mind? The teenager takes a quick glance at it. The rating difference is the most obvious one. Bobby Fischer 2785 vs Boris Spassky 2660, difference of 125 Elo rating points. Although, this time the rating gap is less, D Gukesh 2783 vs Ding Liren 2728, 55 points to be exact. The rank difference is 5 vs 23. Do you agree with the author? Game 1 starts today at 5 p.m. local time, 2:30 p.m. IST. Photo: Maria Emelianova
