```Dear Retro friends,

You can find the tourney announcement here:
http://abrobecker.free.fr/R2020.pdf
http://www.phenix-echecs.fr/Messigny/AFCE.php

Compose a classical retrograde analysis problem (last move(s), legal position, captures...) with the Kamikaze Rex Inclusive condition (B.G. Laws, 1928): A piece making a capture is removed from the board together with the captured man. No other fairy condition, no Proof Games, Illegal Clusters or Retractors.

Some remarks on the condition:
• The number of white pieces will always be the same as the number of black pieces.
• A king cannot defend himself by capturing the attacking piece.
• The two kings can stand on adjacents squares.

Only one problem per external composer (send to abrobecker at yahoo.com before monday 13/07 at 15:00 (UTC+2)). Please send if possible the Forsyth notation of the position as well as a detailled solution.

Happy composing,
Alain

PS: On the PDB, you can see more example KRI problems by typing the following (sadly WPIECES=BPIECES was not working):

G='retro' AND K='Kamikaze' AND (
(WPIECES=1 AND BPIECES=1)
OR (WPIECES=2 AND BPIECES=2)
OR (WPIECES=3 AND BPIECES=3)
OR (WPIECES=4 AND BPIECES=4)
OR (WPIECES=5 AND BPIECES=5)
OR (WPIECES=6 AND BPIECES=6)
OR (WPIECES=7 AND BPIECES=7)
OR (WPIECES=8 AND BPIECES=8)
OR (WPIECES=9 AND BPIECES=9)
OR (WPIECES=10 AND BPIECES=10)
OR (WPIECES=11 AND BPIECES=11)
OR (WPIECES=12 AND BPIECES=12)
OR (WPIECES=13 AND BPIECES=13)
OR (WPIECES=14 AND BPIECES=14)
OR (WPIECES=15 AND BPIECES=15)
OR (WPIECES=16 AND BPIECES=16)
)
