I write a lot about how bad output randomness is for games, but today I want to write about a problem common in many deterministic games – specifically ones that lack hidden information.
Why doesn’t everyone just play chess, if it’s so great? The answer is that chess, or other ancient abstracts like Go and shogi, or even modern abstracts like the Gipf games, Through the Desert or Hive – these games really aren’t that great. They are all largely “look-ahead contests”, and people pick up on this, consciously or subconsciously, and it makes them all kind of annoying to play.

If he should make move A, then I can make moves D, E or F… and so on. It’s literally scanning through every possible (or reasonably valid-seeming) move that you can. Games of chess, at least at novice and intermediate levels of play, tend to come down to simply who does more of this. One way to put it is that it’s a matter of quantity, not quality.
