Long fairy helpmates 3

In the Czechoslovak album 1985-87 I found handful of longer fairy helpmates that can be of interest to our readers.

Long journey by white king to give black necessary free move by pawn. Locusts are very suitable for restricting movement as they cannot move without meal in the form of opposite pieces, but ...

Spotlight comment by Juraj Lörinc:

The chessboard if full of locusts. For less experienced, their movement is as follows: on the queen lines (i.e. horizontal, vertical and diagonal) they jump over the enemy piece and land on the square immediately behind, that square has to be empty and the enemy piece jumped over is captured in the process. This all means that locusts are quite special pieces jumping not on the arrival square, rather on its path to arrival square. For those checkers' players it is something natural, isn't it? But in chess this is exception.

In the diagram position there is only one move by locust possible, namely La7 can capture pa6 by landing to a5. But locusts also restrict move possibilities of both kings. Kh7 cannot move to g8 because of possible L(xg8)h8 nor g7 because of L(xg7)h6. Similarly wK is restricted.

That is why wK cannot immediately capture pawn e3, La7 guards the pawn. If the locust would move away by 1.L(xa6)-a5, white could capture pawn 1...Kxe3, but the he would not be able to break through to the upper side of the board. Therefore white has to take care of La7 first (in moves 1-11), then the king returns and captures the pawn (in moves 12-25) and then heads for capture at g6 (in moves 26-46). Then it is clear why pe3 had to be taken - Black needs a tempo as his king is for a short while confined to h8. The rest is easy - only note that white locust f8 does not guard h5 as there is no square for landing behind.

This helpmate easily beats well known Hegermann's length record, of course, but also naturally cannot be considered a record. Fairy pieces have almost unlimited possibilities and seeing this helpmate in the respective Czechoslovak album was very inspiring for me in early 90s.

... well, Madrasi condition is of course even more restrictive.
