I am checking out the history of this rule, now Article 9.3 in the last FIDE
text. I would be most grateful if anyone with a good library or a long memory
can conveniently add to and/or correct what I have so far:
Ruy Lopez (1561) included a 50-move rule in his 'Chess Code'
anyone got the text?
Croskill (1864) published correct long wins in KRBKR.
anyone got a reference to this?
The London Tournament (1883) rules first stated that a P-push or capture would
zero the count.
again, anyone got the text?
Troitsky (1934) published correct long wins in KNNKP
Russians (1974) publish long KQP(g7)KQ ending - not noticed.
who ... Strohlein, Kommissarchik?
FIDE (1974) published blanket 50-move rule in Article 12.4 with the clause
"This number (50) can be increased [by who?] for certain positions
provided that this increase in number and these positions have been
clearly laid down before the game."
Tinman-Velimirovic (1979, ECO ??) had a potentially long KRP(a2)KBP(a3) ending
anyone got the .pgn of this game?
There was a FIDE Interpretation 12.4 (1978) re KNNKP
what was the wording of this?
There was a FIDE Interpretation 12.4 (1982) re KRPKBP
100 moves for KRP(a2)KbBP(a3)
Thompson (1983) demonstrated 66-move conversions in KBBKN.
FIDE at some time allowed 100 moves for KRBKR
when was this:
FIDE (1988) replaced 100-move clauses by 75-move allowances for
KBBKN, KNNKP, KQKBB, KQKNN, KQP(x7)KQ, KRPKBP, KRBKR
Stiller (1991) found 223-move ending in KRBKNN.
FIDE (1992) binned all exceptions and went back to 50 moves for all.
Stiller (1996) found 243-move ending in KRNKNN: this is the phase-record today.
I am also interested in hearing from anyone who has had a 50-move draw-claim
against them while pursuing a theoretical win.
Thanks in advance for your contributions.
Regards, Guy
