Beating with Grob's Attack. Jobava Baadur (2588) - Klekowski Maciej (2479)

Don't smile at your opponent's opening. Often players can laugh at the opponent's opening, because most strong players are used to seeing solid openings during the game.
Of course, there may be more opportunities for creative play in the blitz, but I'm sure Maciej was laughing when he saw 1.g4 in front of his face at World Blitz 2021!

I hope you have learned a lesson from Baadur and will respect your opponent's "funny" openings.
