- Creation (after promotion of the rear battery piece) and transformations of white Q-R battery into Q-S and Q-R with promoted second front battery pieces – difficult complex shown here for the first time!

- Four different promotions – AUW

- Consecutive play by two white batteries

- BiValve on white 3^rd moves

- The wRb7 opens the battery on four different squares – e7, g7, f7, c7

- Two different pairs of white pieces sacrificed on c4 (S/Q) and e2 (R/Q) on white 6^th moves

“A wonderful synthesis between the fairy conditions Take&Make and Madrasi! Three duos of pieces represent a great content whose finale are nice model mats. Here the "eternal" theme Zilahi is only one of the many interesting components of the problem…” Judge: GM Petko Petkov

b) 1.Rf5 EHc4-c1 2.Rxe5 EHd3-d1#
