Syzygy Problem

[vignottoc]

Hi all!
is there anyone who can explain to me why the Fritz GUI (I have the Syzygy 6 men) does not choose the best move but repeats the moves?

Which Fritz GUI is that? Fritz 17 GUI has a problem with syzygy, unfortunately 3 fold repetition is possible.

[vignottoc]

yes, Fritz 17.

[syzygy]

So the Fritz GUI is buggy.

Either let the engines, not the GUI, play the TB moves, or let the GUI immediately adjudicate the game once a TB position is reached. It makes no sense to let the GUI take over and mess up the game.

[bob]

VERY long-running debate. What is the GUI responsible for? In a classic sense, a "graphical user interface" that ONLY sits between the program and the end user and relays information (passively) back and forth between them. But "some" give the GUI more authority. IE setting the search time, choosing opening book moves, doing endgame database searches, choosing what to ponder and when, etc.

Doubt this will ever be settled. For me ALL of the above belong in the engine. For others, not so much. And this is what we frequently get.

[lovetb]

If it is a blitz game, we have to let GUI play. If you want to use the engine, you will run out of time in the last seconds.
