I propose the removal of puzzle 5 unless someone can prove the solution is good (because the bot disagrees strongly). At the start, KataHex thinks Blue has only a 35% win rate, with either 1. b8 or b10. Move 8 is a mistake; Red f9 instead has a 98.6% win rate. Move 22 at j2 is only 3% for Red; KataHex suggests i6 which is 99% for Red.

Removal of puzzle 5 (done)
I propose the removal of puzzle 5 unless someone can prove the solution is good (because the bot disagrees strongly). At the start, KataHex thinks Blue has only a 35% win rate, with either 1. b8 or b10. Move 8 is a mistake; Red f9 instead has a 98.6% win rate. Move 22 at j2 is only 3% for Red; KataHex suggests i6 which is 99% for Red. Hexanna (talk) 01:01, 7 May 2023 (UTC)
- For posterity, this puzzle has been removed. The puzzles have been re-numbered so the current "puzzle 5" is fine. Hexanna (talk) 15:45, 7 May 2023 (UTC)
- And in case posterity would like to see what the removed puzzle was, it is still in the history. Selinger (talk) 16:20, 7 May 2023 (UTC)
Yes, I wondered about that too. Arek's a strong player, but with 23 moves in the proposed solution, and nothing approaching a proof that the solution works, it doesn't really qualify as a puzzle. It's more like "here is a game that I won". Selinger (talk) 02:16, 7 May 2023 (UTC)
Also, the solution is definitely wrong; the Mohex dfpn solver can prove that 22. i6 is winning for Red. Selinger (talk) 03:17, 7 May 2023 (UTC)
The new puzzle 8
The new puzzle 8 strikes me as another open-ended question similar to the removed puzzle 5. Can it be simplified to get some kind of essential point out of it? We don't have any criteria for what counts as a puzzle (as opposed to a tricky situation from a game where computer analysis showed what the winning move was). But I think one possible criterion is that it should be simple enough for a human to analyze it with sufficient effort at least in principle, and ideally, that the answer is something that can be explained. My point is not that the puzzle is too hard (I am fine with hard puzzles), but that the answer seems to be something that must be verified by computer even after somebody tells you what the answer is.
