Subject: 3 fold repetiton (Seacher v Postmodernist

Author: Frank Phillips

I have obviously misunderstood the law on repetition.  My program assumed the
following game was drawn, since moves 63, 65 and 69 seem to repeat the position
with the same side to move (Kd4, Qb5 btm) ?

Any help appreciated.


[White "SearcherX"]
[Black "PostModernist"]
[Result "0-1"]

[BlackElo "2745"]
