As blitz is chess’ most exciting format, Saturday was a great day at the National Library of India, Kolkata. The day belongs to quick thinking, quick reflexes, and quick hands against common chess skills; it also saw more emotion, guilt, and heartbreak than in any other form of play. The players understand the need for peace of mind to the best of their ability, even though it’s not easy for anyone.

A cool feature used at this event is real-time biofeedback which monitors the heart rate of players who agree to wear a smartwatch that measures and relays it.

The data from the watch, in turn, is retrieved by the Android phone and recorded in real time. All activities are facilitated by Ashwin Subrahmanian who provides logistical support and integrates data with live comments. An engineering manager at Intel, he is an unrated chess player who won the ACO World Amateur Champion in 2018 in the Elo 1600-1800 category. He gave a detailed lecture on the subject during the Global Chess Festival in 2022. After being intrigued, the organizers of this event assigned him to run the system during the Rapid & Blitz India Tata Chess Festival.

The heart rate, in turn, is part of the live commentary, and the broadcast shows the rate on the screen as the players move.

Being able to display the players’ heart rates as they move is a great innovation. It is interesting to watch the numbers fluctuate as the tension in the position increases and the time decreases on the clock.


The open section was a bloodbath with not a single player escaping defeat in the event. Overall, Erigaisi kept his game as stable as possible and often scored wins by exploiting his opponents’ mistakes. An example of this is his game against one of the most prolific blitz chess players in the world, GM Hikaru Nakamura:

Mamedyarov plays his dynamic brand of chess and always comes out on top during fast tactical battles:

Vidit impressed in many matches, the following effort being typical of his style. It’s a well done game, especially by blitz chess standards:

The most dynamic game was played by GM Nihal Sarin, who is our Game Of The Day and GM Dejan Bojkov analyzes below

Much is expected of Nakamura whose iconic status extends worldwide due to his proven prowess in blitz, and he truly shows his genius in an instant, even while nearing the end of the game with little time:

An exciting final day of blitz awaits spectators on Sunday if the combative nature of the game and the prowess of the many blitz specialists in the field is any indication.
