Olli Heimo: Hi! Has anybody a strong enough computer for testing? In 2001 I tested the first 22,5 moves, it took 20 hours, but it does not prove anything. My current computer can check up to 23 moves in a reasonable time. Olli. (2015-02-25)
Henrik Juel: I am afraid that I cannot help you, Olli.
The keyword Albino looks strange in a proof game (2015-02-25)
Olli Heimo: This problem shows four different white pawns moves to e4. Perhaps Albino is a wrong term. In principle it could be possible to have five pawns reaching same square on fourth row, but I believe that it can not be done in a sound proofgame. (2015-02-26)

Henrik Juel: The lengths in increasing order are

One length appears twice, unfortunately
Has anyone made an optimal problem, in 7.5 moves?
Or maybe this task is impossible... (2023-07-10)
