This 3-step method ensures that all 960 starting positions have an equal probability to appear. It is considered to be the simplest method to produce a random Chess960 initial position. It uses 8 playing cards, separated in odds and evens.

**Step 1: Randomly pick one card from each stack. These first two cards are the positions for the two Bishops. **

Obviously there will be one white and one black Bishop. For example, suppose the 5 and the 6 were drawn :

After placing the two Bishops accordingly :

**Step 2: Shuffle the remaining 6 cards and draw 3 random cards. These are the positions for the Queen and the 2 Knights.**

In our example the remaining cards are 1, 2, 3, 4, 7, 8. Let’s say we drew the 2, 1 and 8, in this order:

The new position will be :

**Step 3: The remaining empty squares are for Rook, King, Rook, in this order****, so that castling is possible both ways.**

After placing the last pieces, we get the following position :

And the full starting position will look like this :

The **BOU.LI.NA.** method was devised by Boussios Christos, Likartsis Athanasios and Navrozidis Georgios (hence the name).
