Ludwig held a chess boxing event with a bunch of streamers and YouTubers a few years ago. It was a good watch but he lost a lot of money and said he wouldn't do it again.
I wonder why nobody managed to broadcast his match against... I think it was Alex Clark (maybe I'm wrong). It would've been amazing to see what it was like especially for people who can't afford or don't wanna attend, such as myself. In fact, because of this, I don't even know who won.
Chess boxing, or chessboxing, is a hybrid sport that combines two traditional disciplines: chess and boxing.[1][2] Two combatants play alternating rounds of blitz chess and boxing until one wins by checkmate or knockout. It is also possible to win by time penalty as in normal chess, and by boxing decision if there is a draw in the chess round.[3]
