How To Checkmate in 5D
This is an introduction to 5D chess and how it is different from normal chess, demonstrated with a real match. Imagine you're playing as white here:
You move a knight, and your opponent moves their queen pawn forward:
This exposes a pathway to check their king:
In normal chess, this is a standard opening, and something like this might play out if you tried to check their king with your queen:
But in 5D chess you can exploit a beginner playing this opening really easily! Your aim is to wait long enough so that you can use this pathway not to attack their current king, but their king in the past.
The queen moves N steps in any number of dimensions (where the number of steps has to be the same for each of the dimensions it moves in) . In normal chess, this means, it can move horizontally (1D movement), vertically (1D movement), or diagonally (2D movement):
In 5D chess, it can also move N steps into the past. These are the queen's actual possible moves, of which the previous diagram was just one part of:
If it wants to attack the king in the past, it has to have an unobstructed path when moving along this 'diagonal + backwards through time' path.
The numbers show how many steps in the past the queen would be as it travels through this path. The circled space shows 3, meaning we should put our queen into position 2 turns after your opponent's pawn first moved forwards (2 turns because moving your queen will take up one move, to make 3 turns total).
If you wanted, you could put your queen there first and just wait, but it's more likely your queen will get attacked if you go there too early like this:
So we want to only move our queen when that move will immediately win the game. So, all we need to do is distract the other player by baiting them into taking your other pieces, while what you're actually doing is making sure they dont block this path for the next 3 turns:
So let's distract them by giving them our other pieces while we wait. Use a knight to bait them (it doesnt matter if their king moves, since their king is still in it's original position in the past):
Maybe give them a pawn:
And now that the pathway in to the past is ready.. just move your queen and it's a checkmate.
There is no way they can block your path to the past king, since past pieces are always frozen in time. So since they cannot capture your queen on this very turn, you win the game immediately.
The final move above would not even be a check in normal chess, but is a winning move in 5D, because the queen is attacking the king far into the past:
Note it looks like 8 boards into the past here, but its actually 4 turns, since one turn is a movement by two players and shows as two boards.
The idea of waiting a few turns for the right moment and then attacking is a very common. To guard against this, you can avoid opening up direct paths to your king. Even if you close them soon after, the opening remains there in the past.
