Yes strange that these random moves are not necessarily the best moves. Perhaps its all about confusing the opponent. But that doesn't work if both players follow the same strategy.

Clearly the goal here is to foil alpha-beta!

After all, mini-max, alpha-beta and all other search tree algorithm variants (a-star, b-star, c-star, MTD-(f), you name it...) make a crucial misjudgement! They assume that the opponent plays the best move possible. Now, if the opponent always plays from among the worst moves possible, this is clearly a contradiction of the initial conditions assumed by the search. If an engine happened to be in debug mode, likely asserts would fire, and we would have an abort. Or at a minimum, the opposing engine would ask for a brief recess for the computer equivalent of "Pepto-Bismol" stomach medicine.

[mvk]

Both sides missed a few opportunities.

A better random number generator will certainly fix that. For example, the PGN tags don't seem random at all.

Another example random game, this one ending in checkmate.

This one is very different from the last because white was the only player that was ever on the ropes:

Why are we looking at random games? I must be missing some context...

Why are we looking at random games? I must be missing some context...

I think that we are all wondering that to some degree.
SJE is offering them.
Perhaps they have a real use.
I can't think of what it is, but that does not mean that they are not useful. Only that I can't imagine the use.
