Problem 772: Nikolay Dimitrov (+) - Threemover
dimitrov(02.12.2016) The bulgarian maestro Nikolay Dimitrov passed away two years ago, but his problems are still alive! Few years ago when he started to send originals for KoBulChess I had helping him to chek his problems because he can't use a computer because of his weak and ill eyes. After his death I found a threemover by him on my computer, so now finally it can be published! Thank you maestro and Rest in peace!
   1.Qd8? (2.Qd2#), but 1…Kb4!
   1.Qh8!! (zz)
1…bxc5 a 2.Qd8+ Kb4 b 3.Qd2#
1…Kb4 b 2.Qxe5 bxc5 a 3.Qe1# (2…Ka5 3.Qe1/c3#)
Nice key, cycle ab-ba, selfblocks and light construction - Meredith. (Diyan Kostadinov)

A slight change in the position gets rid of the annoying dual:
Ke1 Qh1 Bb5 P:a4 b2 c5
Ka5 P:b3 b6 b7 e5 e6

Rauf's suggestion.

#3 1.Qh8!

Well, unfortunatelly the author can not share his opinion about it, so probably we should keep the original version. The black moves ab-ba are clear, so the dual in the side sub-variation is not so big weakness in my opinion.
