By this point it’s pretty much basic knowledge that in chess, every piece aside from the king is a girl. Basically pawns can turn into a queen which is a girl, at least in ancient times, so all pawns are girl. But pawns can turn into other pieces except the king, so those pieces are female as well, you get the idea.

The goal of chess is to “capture” the opponent’s king with a girl piece and there is a reason it’s called checkmating. And mating is a euphemism for having sex. So you win when you get your women to fuck the opponent’s king, it’s basically an NTR contest to see who cucks the hardest.

From this we got the lore, both kings have an NTR contest, they both gather girl pieces to attract the other side until the opponent can’t resist. However, both are absolute cuckolds who can’t be lured and it’s too long so the white king decides to cheat. White orders his women to advance and try to fuck the opponent and Black follows soon, the game of chess starts here.

This is why chess is so hot.
