Before we had Locusts, and had KoBul Kings, but now we have the both in one problem! Fine miniature, Aristocrat –
No.16 – hs#4,5 by Petko A.Petkov
The next one – the author of article “Block of Neutral Battery-Piece” shows its theme in his own problem:
No.17 – hs#3 by Petko A.Petkov
Locust (L): moves on Q-lines but only by capturing an enemy unit, arriving on the square immediately beyond that unit, which must be vacant.
Rook-Locust (LR): Moves like Locust, but on Rook-lines only.
Bishop-Locust (LB): Moves like Locust, but on Bishop-lines only.
KoBul Kings: See the definition on Page 1 of Original Problems.
Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.
Nightrider(N): A Rider along a straight line on squares lying a Knight`s move away from each other.

Creation of black batteries B/R after manouevres of black Rook and Bishop which stands in initial position not on the battery-line! Three black half-moves are needed for this goal. Thematic sacrifices of white R and S and creation of non-standard final position in which b.B is pinned and should give mate (because of zugzwang) with a specific for this genre unpining-capture (it changes phase of w. rR into w. rS). Ideal echo-mates with only 6 pieces on the board in Aristoсratic form! (Author)

I.1.Ned8 Ga3! (1…Gh6??) 2.Nh6! Gd3 3.Qc5+! (3.Qe6+?) nLOxc5-d6#
II. 1.Nc2 Gh6 (1…Ga3??) 2.Na3! Gd2 3.Qe6+! (3.Qc5+?) nLOxe6-d6#
Greation of black anti-batteries on the “d”-vertical, created by Grasshopper as rear piece and neutral Locust as forward piece. Play of white masced battery Q/N , combined with thematic sacrifices of the white Queen on c5/e6 – with a goal – attraction of neutral Locusts on square d6. An important moment in this combination is white blocks on a3/h6 – after these N- moves it is impossible for neutral Locusts to leave battery-line. It’s interesting, that on important thematic squares a3/h6 plays White and Black in every solution. Anti-dual tries of black Gd6 and white Queen. This theme belongs to my present article. (Author)
