[Retros] Retro composing tourney

[Pascal Wassong]

Hello Alain,

I am not sure to understand all the differences.  Is the following
correct ?

In Kamikaze, a king can capture and stays on the board.

In Kamikaze RI, a king cannot capture, and opposing kings are NOT
allowed to be on adjacent squares.

In Kamikaze Darlilly, a king cannot capture, and opposing kings are
allowed to be on adjacent squares.

For the RIFACE 2020 composing tournament, we are using this third rule.

Best,
Pascal
