Is Chess960 better? What you gain and what you give up

Chess960 is chess with the back rank shuffled before the game and one castling rule rewritten to cope with it. Everything people argue about follows from that. This page is not about which game is better in the abstract. It is about whether playing it will do anything for you.

Is Chess960 better than chess?

Better at one thing and worse at several, which is why the question keeps producing arguments that go nowhere.

It is better at removing preparation from the result. Two players sit down and neither of them has been in the position before, so whatever happens next was produced at the board. Nothing else about it is an improvement. Standard chess has the books, the coaches, the events, the opponents and a hundred and fifty years of tested ideas, and Chess960 has almost none of that.

The straight comparison of the two games, rule by rule, is set out in Chess960 versus standard chess. The rest of this page answers the narrower question people are usually asking, which is whether it is worth their evenings.

What are the benefits of playing Chess960?

The strongest one is that preparation stops being the price of entry.

Consider what it costs to play 1.e4 e5 in standard chess with any confidence. You need something against the Ruy Lopez, the Italian, the Scotch, the Four Knights, the King's Gambit and the Vienna, then the same work again from the White side, then a repair every time somebody finds a hole in one of your lines. None of that is talent. It is an entry fee, paid in hours, before you reach a position where you are actually thinking. Players with time to spend pay it and players without do not, and the gap turns up in results that were settled before either of them arrived.

In Chess960 the fee is zero, so the hours go somewhere else. On move three you are doing what you would otherwise be doing on move twenty-five: looking at where the pieces are and working out where they belong. If you play twice a week and study for an hour, that hour goes into calculation and endings instead of into a file of variations.

The second benefit follows from the first and is smaller. Your losses become legible. Losing a standard game to a line you had never seen tells you the line exists. Losing a Chess960 game almost always leaves you with a move you can point at.

Is Chess960 good for beginners?

It has a real advantage for beginners and a real cost, and most answers give only one of them.

The advantage is that a beginner is not scored on a body of knowledge nobody has taught him yet. He is scored on whether he saw the fork. Beginners lose to preparation all the time in standard chess without knowing it, because a trap sprung on move nine is indistinguishable from being outplayed.

The cost is scaffolding. A beginner in standard chess gets more than principles. He gets the same positions again and again, and repetition is most of how anyone learns early on. Play forty Italian Games and the bishop's retreat to b3 stops being a calculation and becomes a thing you know. Chess960 removes the repetition and leaves the principles standing on their own, and principles with no worked examples under them are thin.

There is also far less to read. Shelves exist for the standard openings. For Chess960 there is very little, and nothing a beginner could work through game by game.

The sensible answer for someone starting out is both games, doing different jobs. Learn the shapes in standard chess, where the examples are. Play Chess960 to find out whether you understand a principle or merely recognise a position. The rules take five minutes to read, and the walkthrough of a first game covers the practical side.

SP 269 · NRKBNQBR
Position 269, with the king and the two soft pawns marked. In the ordinary array the one pawn defended by nothing but the king is f2, and every beginner gets told so. Here it is d2, and a2 has no defender at all, because the rook that normally stands behind it is on b1. Nothing to memorise, and nothing to fall back on either.

Is Chess960 harder than chess?

Two different questions get asked in one sentence.

It is harder to prepare for, in the strict sense that preparation is not possible. You cannot arrive knowing anything. If that is what harder means, it is as hard as a game gets.

It is not much harder to play. The pieces move the same way. Every tactic, every ending and every pawn structure is untouched, and all sixteen pawns start where they always start. From about move ten onwards you are playing chess and would not know anything unusual had happened. The extra work sits in the first ten moves, and it is a countable kind of work rather than a deeper one. What you have to establish is where your pieces can go and what is standing in the way.

Five pieces in the way · RKBNQBNR
Position 23: the king already stands on f1 with a rook on g1, so White may castle short at move one and the two pieces simply swap. Position 726: the five marked pieces all stand between the king on b1 and the g1 it is heading for, and the quicker route is the other way, where castling long slides the king one square to the right. That is the extra difficulty in full, and it is arithmetic you can do before touching a piece.

The clock is where you feel it. Time that the first ten moves used to cost nothing now gets spent. The cure is a routine you run before move one, which the Chess960 strategy guide sets out.

Does Chess960 make you better at standard chess?

Here is the honest version, with the reasoning and the evidence kept apart.

The reasoning: playing positions that have no known answers forces you to calculate rather than recall, and to judge piece placement from what is in front of you. Those are the faculties a standard middlegame asks for, and doing more of something usually improves it. That argument is plausible and it is all anyone has.

The evidence: there is none worth the name. No study measures rating gain from playing Chess960, and anyone who quotes you a number for it invented the number. Treat the claim as reasoning, because reasoning is what it is.

Two things can be said flatly. Chess960 will not improve your opening knowledge, and if you lose standard games by getting outplayed on move twelve of a line you half know, it does not address that. What it does is show you which of your results came from understanding and which came from familiarity, and that is worth knowing whichever answer you get.

Is Chess960 the future of chess?

Nobody knows, and the people saying yes are guessing from the same evidence as the people saying no.

What would have to be true for it to become the default game. Enough serious events would have to use it that results in it carry weight. A body of teaching material would have to exist, because improvers study and there is little to study. Casual play would have to be as easy to start as standard chess, which over the board it is not, since somebody has to randomise the array and place sixteen pieces correctly. And spectators would need a way to follow a game whose opening nobody in the room recognises.

None of that is impossible and none of it has happened at any scale. Magnus Carlsen and Hikaru Nakamura are open advocates of the variant, which is worth one sentence and no more, because who endorses a game is the weakest reason there is to play one, and endorsements age badly.

What are the honest reasons not to play it?

Some of the objections are answerable and some are simply true.

The study problem is true. If you improve by reading, there is not much here for you, beyond a tactics trainer built from Chess960 games and the books that collect those puzzles.

The setup is a nuisance over the board, which is much of why nearly all of it gets played online, where it is one click.

Opponents are harder to find. Most clubs run standard events, and a game of Chess960 is usually something you arrange rather than turn up to.

Not every arrangement is equally fair to both sides. The usual fix is to play the same position twice with the colours swapped, and it costs nothing to copy in a casual game.

Some players enjoy the preparation. If the part of chess you like is an evening with a database and a line you are trying to repair, Chess960 deletes it and hands you nothing in its place. That is a preference about how you want to spend your time, and there is no argument against it.

The opening can feel formless. For the first few games you are arranging furniture with no idea what the room is for. That passes once you know what to check, and a fair number of people play three games, feel nothing much, and go back.

Who should play Chess960, and who should not?

Play it if your games are decided in the middlegame and you resent the ones that were not. Play it if you are returning after years away, since tactics survive that gap and opening knowledge does not. Play it if you get an hour a week and want the hour spent on chess rather than on maintenance.

Skip it if you enjoy the preparation, because you would be giving up the part you like. Skip it if you have a rated standard event next month, since your time goes further on your own openings and your endings. And skip it if what you want is a shortcut to a higher standard rating, because tactics and endgames are still the short route.

Three games settle it either way. Deal an arrangement with the position generator, play it against the computer, and notice whether the first ten moves feel like work you want or work you resent.
