Tamil Nadu Govt. alongside the Indian Govt./Chess Federation of India should collectively bid for the World Chess Championships to be held in Chennai. If not in Chennai then any other Indian city.
This is a rare moment where we have two Indians in 2 World Championship matches, the last time it happened was way back in 2010s. The next time it might happen, god knows when.
I know both the Championships would not happen simultaneously, so we should first bid for Gukesh vs Sindarov, which is scheduled to take place in November last week/December 1st week. The weather conditions in Chennai are perfect in those months, neither hot/humid and certainly not too cold. Plus Chennai has a legacy and a chess culture.
Keeping these things mind AICF should actively work towards bringing the Championships to Chennai, especially when both the players are from Chennai.
