Yoav Ben-Zvi: The cook found in P0002554 re-opens the question of the current length record for unique capture-free SPG. A search in PDB finds this problem, assuming it is sound, to be the record holder, until Unto Heinonen publishes a correction (expected very soon). Prior to publication of this problem the record was 38.5, in Michel Caillaud's P0002187. (2019-07-10)

James Malcom: And thus, another giant falls. (2021-02-13)
A.Buchanan: Did Unto find a fix? (2021-02-14)
Michel Caillaud: Unto published a correction of P0002554 in StrateGems (42,5 moves, january 2020), not C+ of course... (2021-02-14)
James Malcom: May you input it into PDB please, Michel? (2021-02-14)
James Malcom: Thanks for the email, Michel. Unto's correction can now be seen in the database: P1386520 (2021-02-15)
