Maximummer

The helpmate post got me thinking about all the wonderful variations of our game. A maximummer is where Black has to make the geometrically longest move, not a puzzle as such, more an artform.

But, chessplayers thrive on challenge, and soon the double maximummer made its appearance, where BOTH sides have to play the geometrically longest move.

The record for this type of task is 100 moves, leading to mate. Play through it, it's fun...

Never in all of these 100 moves is there a choice - the whole thing works all by itself, like a witty, self-destructing clockwork.

WOW!

on move 38, is the diagonal just longer than the 4 squares which the queen can take the rook with? because otherwise 4 squares should be longer.

9+9 = 18. Square root of 18 > 4?

nvm yeh it is because 4 squared is 16 and 18 is bigger =D

Wow.

Shit, this is insane I'm glad heavyquarter happened to be going through 6 years old threads. Or did you find this in google?

This doesn't make any sense so I'm going to assume you meant move 37 and that you were comparing Bxe5 to Qxa3 (by the way I'm pretty sure the coordinates are inverted in the initial position).

I have no idea where you get the 9+9 from, but the OP specified GEOMETRICALLY so we can assume it means the distance between the centers of the starting and ending squares of the moving piece. Therefore, a diagonal move to the nearest square is sqrt(2) long, which is about 1.41 if I remember correctly. This means a move 3 squares long in a diagonal direction is worth 3*1.41 units = 4.23 units. Therefore, the queen move is actually shorter and the rule is respected. I checked the rest of the sequence and that rule seems to be followed all along.

By the way, this is the reason that, in standard maxinummers, only black makes his longest move. There isn't be a great deal of solvng challenge left when both black and white just make their mandatory longest moves. Aside from the occasional 'equal length free choice' that is.
