Подборка задач где изначально все фигуры стоят как перед началом шахматной партии, почти во всех задачах решение единственное, сложность средняя, но покрутить позицию придется.
Для разминки - в начальной позиции ходят только белые причем только одной выбранной фигурой, если пешка то ей и превращенной из нее фигурой. Нельзя давать промежуточные шахи королю черных. Надо поставить мат к 8-му ходу.

The following are a set of chess construction tasks. In these types of puzzles, you have to construct a (short) game that conforms to the given set of conditions. These puzzles are so difficult that they have stumped grandmasters. All of them either have a unique solution or a solution that would be unique except for some trivially different alternative.
- White’s first four moves are 1.f3 2.Kf2 3.Kg3 4.Kh4. Black delivers checkmate on the fourth move.
- White’s first move is 1.a3. White mates with the a1 rook on the fifth move.
- White’s first move is 1.e4. The fifth move, by white or black, is NxR mate.
- Black checkmates on the fifth move by promoting a pawn to knight.
- Black checkmates on the fifth move by promoting a pawn to a bishop.
- White checkmates on the sixth move with gxf8=N
- Checkmate, by black or white, is delivered by the b pawn on the fourth move.
- Whatever move White makes, Black has to mirror the move (e.g. Nf3 by white has to met by Nf6 by black). After white’s eighth move, black cannot legally mirror white’s move. Black’s only legal move checkmates white. This one is due to that great puzzlist, Sam Lloyd.
