Why do we find acceptable that at the start of a game of Chess, white not only has the move and thus the undeniable initiative, but white also does not have to think on his first move in the slightest and his clock is not penalised? Black on the other hand has no idea of what they will be facing, is almost guaranteed not to have the initiative and has the double punishment of having their clock ticking down?
...
All black has to do to remove this imaginary advantage is to prepare an opening move for each of the 18 possible first white moves. Then you could make an equally (in)valid claim that it is white who is the first one to have to think. But in truth, both players have to think during the opening, perhaps only as soon as the opponent comes up with a move that they are not totally prepared for. If you have to think early in the opening, this is usually a good thing as it means your opponent has played something unusual, which more often than not means something slightly inferior.
White does have a practical advantage from the start, probably best expressed as having a little more freedom in what they can play without compromising their position, but this is entirely separate from "having to think" or not.
CapAnson: 'That is in fact the problem with chess 960... It's by and large a game only for 20 or 30 people in the world, for everyone else it's a novelty.'
The idea is so new that it's a novelty for everyone, but I accept your point. I also wonder whether it's more interesting for experienced players than for beginning chess players. Time will tell.
As for how experienced you need to be to appreciate it, I think most class A players (rating 1800+) know that opening preparation goes a long way to getting a good game. It would be interesting to conduct a poll asking 'When you study chess, what percent of your time do you spend on A) the opening, B) the middlegame, C) the endgame, D) Other [history, for example]', then correlate the responses according to rating. I wouldn't be surprised to find average club players and below (<1500) spending a lot of time on openings.
What got me hooked on chess960 was being forced to think about the game starting with the first move. It's not at all the same as reeling off the first 10 moves of a Closed Lopez (or Poison Pawn Najdorf, or King's Indian Bayonet Attack, or ..., or ..., or ...) from force of habit, then relying on preparation for the next few moves, then really starting to think creatively somewhere around move 15. With chess960, the creative thinking starts when you see the initial position. You don't have to be a GM to enjoy that. Isn't the intellectual challenge one of the reasons we play chess? - Mark
