Format for 14.05.2022:
Participants: Open to all ECSC 2022 participants.
Skills: Solving skills (to assure the correctness of the problems without using computer),
imagination (in inventing solutions and correcting positions).
Difficulty and the content of solutions: Mixed, from easier to more difficult, and from banal to more or less artistic.
Writing and points: Solvers should give only one reply to each task. Correct reply scores 1 point.
Tiebreak criteria: The time used for solving.
Stipulations -> solutions to give:
- #2 (mate in two) -> give the unique key-move by White
- endgame (draw / win) -> give the unique key-move by White
- h#2 (helpmate in 2) -> give the unique sequence of all four half-moves
- h=3 (helpstalemate in 3) -> give the unique sequence of all six half-moves
More complex changes:
- twin / N solutions -> give solutions for each different added piece (Example 3)
- add several pieces to reach the given final position (Example 4)
