Indian Grandmaster R Praggnanandhaa stunned World No. 3 Fabiano Caruana 3.5-2.5 via the tie-break in the semi-finals of the FIDE World Cup chess tournament here on Monday.

After the two-game classical series ended 1-1, the 18-year-old Indian prodigy outlasted the highly-rated American GM in a battle of wits in a nerve-wracking tie-breaker. Praggnanandhaa will now take on Norway’s Magnus Carlsen in the final.
