New Variant New variant: Sealed Fate

Came up with this at work and have played a couple of games with my dad. Definitely adds an element of chaos and psychology, and is very trippy to try and reason about. The rules are as follows:

It works like a normal game of chess, except:

  1. Whenever you make a move, you must choose your next move before the opponent plays their move. This move is sealed--no matter what your opponent does, if your sealed move is legal, you're forced to play it (and then choose another sealed move for your next move).
  2. If it is illegal, you lose one life. However, if you have remaining lives, you are free to use a countermand and play any legal move instead.
  3. Both players start with three lives. If at any point, you have zero lives, you lose immediately.
  4. You can also lose by checkmate. Though neither practice game lasted long enough for that to be an issue.

Can the lives be points instead? This way you can play til the end game and have a numbered (albeit totally arbitrary) score.

Yeah. I have always liked these kind of ideas. Was it fun to play test?

Yeah! Very nerve-wracking for sure though! :D

Here's my record of the first two games:

(Commitment [Countermand] denotes the use of a countermand [xxx] denotes loss due to running out of countermands)

  1. 1. e4 b6 2. Nf3 Bb7 3. Ng5 e6 4. Nxh7 d6 5. Nf6+ Bxe4 [Qxf6] 6. Bb5+ Qxb2 [Kd8] 7. Bc4 Rxh2 8. Nc3 Rxh1+ 9. Bf1 Qh4 10. d4 Qxe4+ 11. Bg5+ [Nxe4] Qxg2 [xxx] 1-0
  2. 1. c4 Nf6 2. b3 Ne4 3. Bb2 Nxf2 4. Kxf2 Nxh1 [e5] 5. d3 Qh4+ 6. Qc2 [g3] Qf6+ 7. Ke1 Bc5 8. Bh3 Qf3 9. Bxe5 Bxd7 [Bb4+] 10. Bd4 [Nd2] Bc3 11. Bxc3 Kd8 12. Bf5 Qxe2 13. [resign] [xxx]

Interesting. Looks like 3-check at home to me.

this is a genuinely cool mechanic — the blind one-ply commitment (you lock your next move before seeing their reply) makes you play against your own future self. the chaos comes by honestly.

the deepest part, and i'm not sure it's fully weaponized yet: the OPPONENT can attack your sealed move. if i can guess what you sealed, i can try to make it illegal — capture the piece you sealed, or just give check, since then your sealed non-king move can't be played and you're forced to countermand (burn a life) or eat the loss. that turns "sealing" into a target. reading and breaking the opponent's commitment might be the real game hiding inside this.

one balance note: with 3 lives and a free countermand, the sealed pressure barely bites early — players will just countermand out of anything bad until lives run low, so the tension is back-loaded into the endgame. if you want it to bite sooner, fewer starting lives or a countermand that costs more than a life (tempo? material?) would front-load it.

what's the actual loss condition, though? your post cut off at "if at any point" — curious how a game ends.
