No.361 by Juraj Lörinc –  A complicated s#6 with interesting Kobul Kings motives!  (JV)

Definitions:

KoBul Kings: When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again. Сaptures are illegal if their result is self-cheсk because of the transformation of the Кings according to KoBul rules. Castling is allowed only if the KoBul King is on his initial square in the form of a normal King and if he has not already moved; however he may already have been transformed. In the case of capture by a King in AntiCirce he is reborn on his initial square and may castle. If the capture is by a King which is in the form of some Royal piece, he is reborn on the initial square of that piece.

 No.361 Juraj Lörinc Slovakia original-24.08.2013   s#6                                      (12+5)   С+KoBul Kings   Solution: (click to show/hide)   1.Ba1! zz ([2.Ke8 …])1…b×c6 2.rSe6 c5 3.rSf8 c4 4.rS×h7 c3 5.Qh4+ Kf5 6.Rf8+ Kg6#1…b×a6 2.rBe7 a5 3.rBc5 a4 4.rBg1 a3 5.Rh4+ Kf3 6.Qe3+ Kg2# Two model mates by the black king. There is some analogy between two variations: moves W2-W4 transport white royal piece to square where it would be mated, both W5 to h4 allow passage of bK, W6 blocks besides forcing the mate. There is only one KoBul Kings selfmate in the big WinChloe database so far. Constructional remarks:· After the key there is actually dualistic threat 2.Ke8 etc. with mates by bK on e7 and f7 to wK transformed to rS, however, the threat does not show in actual play as black is forced to capture in B1.· The key is not particularly exciting, stripping black of pawn promotion, but  · this might be seen as paradox in selfmate where black needs material to mate with only black K&P on the diagram,· the key is the best possible found – move to corner, no capture, no flight taking, and even no evacuation from en prise position. · Actually the construction was very difficult given the main theme, with looming cooks and duals throughout (anyone doubting may try something similar).
