mate test positions

[abulmo2]

I accept the format but I do not like the order of problems that is lexicographic order and I prefer order based on distance to mate and I also do not like not having the move number and the fifty move counter that was in the original file because positions are from games but later is not there after Richard Delorme edited it and I copied from him with some corrections.

Move number and fifty move number are not encoded the same way in EPD and FEN format. In EPD files they are optional and should be preceded respectively by fmvn and hmvc:

16.2.5.13: Opcode "fmvn": fullmove number

The opcode "fmvn" represents the fullmove n umber associated with the position.
It always takes a single operand that is the positive integer value of the move
number.

This opcode is used to explicitly represent the fullmove number in EPD that is
present by default in FEN as the sixth field. Fullmove number information is
usually omitted from EPD because it does not affect move generation (commonly
needed for EPD-using tasks) but it does affect game notation (commonly needed
for FEN-using tasks). Because of the desire for space optimization for large
EPD files, fullmove numbers were dropped from EPD's parent FEN. The halfmove
clock information was similarly dropped.


16.2.5.14: Opcode "hmvc": halfmove clock

The opcode "hmvc" represents the halfmove clock associated with the position.
The halfmove clock of a position is equal to the number of plies since the last
pawn move or capture. This information is used to implement the fifty move
draw rule. It always takes a single operand that is the non-negative integer
value of the halfmove clock.

This opcode is used to explicitly represent the halfmove clock in EPD that is
present by default in FEN as the fifth field. Halfmove clock information is
usually omitted from EPD because it does not affect move generation (commonly
needed for EPD-using tasks) but it does affect game termination issues
(commonly needed for FEN-using tasks). Because of the desire for space
optimization for large EPD files, halfmove clock values were dropped from EPD's
parent FEN. The fullmove number information was similarly dropped.

positions are taken from pgn

Here is an analysis of one pgn with better mate scores for part of the cases
I do not claim that the long mates are optimal and there may be shorter games

Here are the first positions in the epd file ordered based on distance to mate(all of them except position number 24 from this game or maybe it is better to order based on game and after it based on move number so the order does not change if I find a shorter mate)

I saved the move number but did not add fmvn and hmvc before the numbers
I am not sure if for this I need to write in epd file instead of
6R1/1k1PK3/p3P3/7p/6p1/8/5r1P/8 b - - 4 42
something like
6R1/1k1PK3/p3P3/7p/6p1/8/5r1P/8 b - - fmvn 4; hmvc 42;
