# Why is Chess960 is called Chess960? Is it because it have 960 different starting potisions?

It is the reason.

BTW, the starting position you've shown is *not* a legal 960 starting position.

The rooks are on one side of the king, which is illegal.

^That is a legal position. It's not the same as the one in post #1.

And I have no clue. Chess960 sounds better to me, and English is my first language, or pretty close to it at least.

no, it's because there are 960 different dumb questions about why it's called chess 960.

Lol

Yes.

- 4 white squares for 1 bishop, 4 black squares for the other bishop
- Then there are 6 available fields for the lady
- Then there are 5 available fields for the 2 Knights (10 posibilities)
- Then the remaining King and Rooks can only be placed in 1 way

4*4*6*10*1 = 960

no, it's because there are 960 different dumb questions about why it's called chess 960.

Now it's 961

but @Serphiot, how can we know that all those positions (960 of them) will be such that the rooks are not on the same side of the King... does not seem obvious...

He puts the king and rooks on last.

If there are 3 slots available, exactly one permutation will have the king between both rooks.
