# Can 5D chess be solved?

An interesting new variant of chess has emerged, showing that chess will always be fresh-5D chess.

I mostly play the 5x5 version, but the positions do not rocket out of control like in the standard 8x8.

Given its uncomplicated nature, with current computing power, could it be possible to solve this variant of chess?

This link explores a way that white can force a draw. Perhaps this is game-breaking and makes the solution process much easier.

I am only an casual chess player and I’m mainly transcribing “5D Lexi”’s analysis.

My attempt at transcribing it (there’s no standard notation for 5D chess)

1. e3 Kf6
2. Bb5 c6
3. c3 ...

The idea is for white to go for Qb3 and then Queen to f7 to move 1. Black should not play cxb5 because he needs active counter play against this idea.

1. ... Qc7
2. Qb3 d5 (defending this timeline)
3. Qf7 to turn 1 (check) Kxf7 (the following is all in this new timeline)
4. Kf3 Kf6
5. Ke5 one move back in the same timeline (critical move)

Note: the new timeline is an inactive timeline, so Black doesn’t have to play here. This might be the reason that it’s a forced draw, not a win.

Now, black has difficulties creating another timeline without losing. Because if Black time-travels to a location after move 2, then the present is shifted to move 2, but white’s Knight is checkmating Black’s King on the adjacent timeline.

Black can conceivably travel further back, to turn 1, to defend.

Honestly just watch the video :)

• Link only answers are not allowed because if the link dies the answer becomes useless. Could you expand on what is behind the link, please? Perhaps explain how white forces the draw? Dec 30, 2020 at 21:07
• @Brian Towers alright will do it soon -- it's midnight here now. If someone else wants to take it and write an answer it's okay too. It's the first few minutes of the video Dec 31, 2020 at 0:39
