I have seen a position with id. You place it in c2 perhaps because later on you will use your own id.
pos 34.
Code: Select all
8/6pp/1K6/N5P1/3N4/8/npn1P3/k7 w - - bm Nab3+; c0 "Lommer 1963"; fmvn 1; hmvc 0; id "Nightmare Nr.020"; c1 "diff=6";
Something like this.
Code: Select all
8/6pp/1K6/N5P1/3N4/8/npn1P3/k7 w - - bm Nab3+; c0 "Lommer 1963"; fmvn 1; hmvc 0; c2 "id Nightmare Nr.020"; c1 "diff=6";
Then you can improve it further by placing hmvc and fmvn next to bm id, then arrange the comments, c0, c1 and so on. A really smart gui will give hmvc and fmvn as aditional info, to complete the fen specs, as input to uci engines. If position has no hmvc and fmvn then just forget it of course.
Like this.
Code: Select all
8/6pp/1K6/N5P1/3N4/8/npn1P3/k7 w - - bm Nab3+; hmvc 0; fmvn 1; c0 "Lommer 1963"; c1 "diff=6"; c2 "id Nightmare Nr.020";

The id's come from other suites, I copied the whole lines.
I really focus on positions correctness currently.
In the next step, I'll make a PGN file with the best variation(s) and name of the players/composers.

There is a bit of analysis of the ones I did not have solved already here:

These are the 18 that seem hardest for Stockfish:

Not sure how that last one got in there, it looks like a test run of some sort.

This one sure looks like the work of Valentin Albillo, but his web site is no longer up so I can't verify it.
