Invented by László Polgár, father of the famous Polgár sisters, Starchess is played on a star-shaped board with rules which are very similar to those from classical chess. This chess variant seems very suitable for endgame study composition.
The end position is the following mutual zugzwang:
In the solution, the white king triangulates trying to reach the same position but with BTM. In order to find the correct first move, one has to see the final mutual zugzwang! These kind of long triangulations are very rare even in chess studies.
During solution, two dead white pawns are coming back to life. This theme is impossible in chess.
The white knight and the black king follow these paths during solution:
Black avoids two echo stalemates by echo promotions to bishop!
