Gukesh D is just ten years old and is playing in both the Open and U-13 Tournaments simultaneously at the IIFL Wealth Mumbai International Tournament/
That's 18 games in nine days and he is not the only one here who is doing this!
He is not even the best in his age-group in India, just among the top, ten and yet he is already having a rating in excess of 2200!
Not just 2200+ rating but also the playing strength of a 2200.
With these players, holding or beating GMs and IMs are not uncommon and they work hard not thinking of short term results but to get really really strong.
