fuego13 vs AyaMC
In round 5, AyaMC played move 13 as shown to the right, against fuego13.
This seemed odd to me. My thoughts were "I can see that it wants to save the
cutting stone at e5, but this doesn't work, White can now play at f5 and catch
the stone in a ladder. That's strange, AyaMC is a solid reliable program, it
does not normally misread ladders". Fuego13 did play 14 at f5. AyaMC played
tenuki with 15, and went on to win the game.
I don't know whether AyaMC really misread a ladder here, or whether the exchange
of 13 for 14 was good for Black. Aya is much stronger than me, particularly on a
small board, so its move 13 was probably good, though I still think it looks strange.
Hideki Kato has confirmed my views about move 13, writing "Zenith 4 (English
version of Tencho no Igo 4) preferred F5 as the third best (first is D5) and the
winrate of Aya dropped after W F5. You're right, B F4 must be bad (at least worse
than F5). Possibly a bug.".
