Hi,
as it plays fast on modern hardware even at tournament setting, I gave a try to more depth and/or width. Sadly the deeper/larger the search, the higher the probability for a crash with a 'Push down list overflow' msg.

So I sticked to the usual tournament settings.

But a crash can still happen. I faced one after five games played without any issue, thus not a so often case.

The good news is I could easily resume the position and start a lower search (depth 5 instead of 6), get the Mac Hack move, increase again the search and complete the full game without anymore issue.

How to? I copied the TTY output of the game to a text editor to empty the unwanted output characters (such as _W prefix for moves played by the program as White), removed the play command (PW or PB) to ensure "referee mode", then pasted back into a new/clean CHESS program run. The CMD Windows lets you paste several lines that will feed the Mac Hack session. You then just need to set the appropriate level and enter PW or PB command to resume the search.

Should Michael (or anyone) want to test/reproduce, here is a TTY input for the position that crashed using tournament level:Just change the first line to SETD 5 for a safe run.

If any useful, the standard notation:

Ja, das sehe ich genauso
Habe es zum Laufen gebracht, aber werde es wohl nicht weiter untersuchen.
Da gibt es noch sooo vieles anderes, was auf meine zeitliche Zuwendung wartet

Aber nochmals vielen Dank für das alte Schätzchen.
Beste Brüße
Michael

mit LIST kann man sich Commandos / Parameter anzeigen lassen.


Eine spätere Version hat hier eine 'Dokumentation':

Spannend ist zum Beispiel:
SMVD 1
(give analysis of principal variations stemming from each plausible move)
PSVD 1
(print principal variation and its value..)

M - einen Move machen lassen.
PS - automatische Partie spielen
U - Undo move

etc.

Ich finds jedenfalls höchst interessant, habe auch schon Partien in der desktriptiven Notation gespielt

Hier mal eine Partie Sargon 2.5 (ohne Pondern) gegen Mac Hack VI auf Turnierstufe. Sargon kam arg in Bedrängnis.
