| BUL Lion: | Moves like a Lion ((0,1)+(1,1)Prolonged Hopper), but the hurdle must also make a non-capturing Lion move (the move is impossible if it cannot). | |
| BUL PAO: | Moves like a Pao ((0,1)Chinese), but the hurdle must also make a non-capturing Pao move (the move is impossible if it cannot). | |
| BUL VAO: | Moves like a Vao ((1,1)Chinese), but the hurdle must also make a non-capturing Vao move (the move is impossible if it cannot). | |
| Chinese (m,n) (family): | Without capture moves like (m,n) Rider, with capture – like (m,n) Lion. | Китайская фигура (m,n). Без взятия ходит как Линейная фигура (m,n), со взятием – как Лев (m,n). |
| Lion (m,n) (family): | Moves along lines of (m,n) Rider over another unit of either color to any square beyond that unit. A capture may be made on arrival, but the hurdle is not affected. | Лев (m,n) (семейство). Ходит по линиям Линейной фигуры (m,n), останавливаясь на любом поле после первого препятствия на этой линии. Фигура на поле прибытия может быть побита, фигура-препятствие остается незатронутой. |

an essential role in the final position} 1.LId5-d7[bPd6->d8] Bf7-d5 2.PAd1*d5[bRd2->d3] LIe3-b3[wRd3->a3] { } 3.VAg8*c4[bPAd5->e6]+ LIb3*e6[wVAc4->g8] # {/ LIb3*e6[wVAc4->f7]# Not 4.g2-g3?? LIe6*h3[LIf5-c8] which shows that wLId7 has
an essential role in the final position }

Probably this is one the first examples using Bulgarian pieces of the very difficult "Avant-Garde Indian theme" invented by Petko Petkov.
The black batteries Be6-LIf5 and Rd3-LIe3 are translated on the same lines Bc8-LId7 and Ra3-LIb3 before firing.
From a merely strategic perspective, the rest of the play contains also some interesting aspects: three duos exchanging roles, Black-White Follow-My-Leader with black active sacrifice, diagonal-orthogonal correspondence, double check vs double check.
From the fairy specificity point of view, 5 out of 6 moves are "danced" by the Bulgarian pieces, with lots of interplay effects.
The white pawn g7 ensures the soundness of the second solution - without it, there is no solution: 3... LI:e6(VAf7) 4.LIg7(VAb3)!! and the bLIf5 has no longer a hurdle!
PAP’s example.
