So this new variant will be called Acceleration chess. Basically, it's normal chess but you can make 2 moves in 1 turn if you want to. You can use it 3 times in one game and here are some rules to make the acceleration skill not too op.
Rule 1: You can't move one piece twice during the acceleration skill
Ex: When you play e4 and Bc4, you can't accelerate and go Qf3 or Qh5 and then go Qxf7 mate as it is moving the queen twice during the acceleration skill. (You can, however, move the queen on your second turn and in your 3rd turn, accelerate and go Bc4 and then Qxf7 mate as it is moving the Bishop and the Queen.)
Rule 2: You have to get out of check immediately and you can't be in check during the acceleration skill
Ex: When your opponent checks you, you can use your acceleration skill but you have to get out of check during the first move.
Another ex: You can't move an absolutely pinned piece unless you unpin it in the first acceleration move. You can move it in the second acceleration move if you get unpinned during your first acceleration move.
Rule 3: You can check during your first acceleration, but, however, you cannot check again after the first acceleration as double check will be too op lol
Rule 4: Acceleration has a cooldown of 3 turns before you can use it again.
How does it sound? Is it good? You can criticize me in the comments and suggest what to fix to make it more fun.
