There is a chess variant called Progressive Chess, where the number of moves per turn increases with each turn. In this variant, White starts with one move, then Black plays two moves, White plays three moves, and so on. The players alternate turns, and each time they play, they make one more move than their previous turn. This creates a unique strategic dynamic and requires players to think differently than in traditional chess.

I almost never play chess, but when I play chess I usually play this variant, because it's faster and people don't have any tactics memorised. I'm not even sure if it's possible to memorise in the same manner as regular chess.
