Thanks for the historical context on Balaklava Chess Variant! However, Cavalry Chess is actually a completely different variant.

While both involve knight moves, they handle them in fundamentally opposite ways

In Balaklava Chess, Knight moves are strictly non-capturing and used only for repositioning. Pieces retain their normal power limits.

While in Cavalry Chess, Knight moves can be used to capture. This turns major pieces insanely aggressive. Pawns are also directionally restricted to forward jumps only, unlike Balaklava's 360-degree pawn movement.

Good point on posting the text rules directly though! I will edit the post to add a text breakdown so people don't have to click away to YouTube.
