It is more than just a flashy proverb. It is astute. And often ruthlessly true. Witness the Russian star Nepomniachtchi’s games at the Zagreb Grand Tour where the audacious …g5 was played early in the opening.
First, in round 1, playing Black against former World Champion Vishy Anand, Nepo’ played g5!? as early as move 6. Anand was shocked and very quickly found himself with a lost game after some meek play. Seeing is believing:
Then in today’s game (round 4), this time playing White against former World Champion challenger Karjakin, Nepo was given a taste of his own medicine as early as move 9. His opponent quickly build up a strong attacking game and it was something of a minor miracle that Karjakin did not win!
