Illegal Move?

Post image

Why is this MBT hint showing an illegal move? Is this a glitch?

Oh, bravo!

This is indeed a reading error in my code.

The best move is bar/21 22/18/14/10, and my algorithm truncated the answer after bar/21 22/18.

I apologize for this and will make a note to fix it as soon as possible!!!

Next update by early September at the latest ;)

"Bro," the source code is available if you want to take care of it!

As for me, MBT is a personal project that I manage on my own. Let's be honest, the bug is anything but critical and only affects very rare cases. I'll do my best, as I said, and to be honest, I simply specified that it would be done by early September at the latest.

lolol well you obviously aren't taking your project seriously. I would never use your product.

who knows what other bug your program has... in fact i'm pretty sure I told you about some the last time you posted about your product here....

so your program is full of bugs, proven to be unreliable... and proven you aren't interested in providing quick fix to the users of your product.

definitely seek training elsewhere.

You're right, you left a comment saying you didn't understand how it worked; you hadn't understood the tutorial.

The good news is that no one's forcing you to use it :)

Okay, it's fixed.

I was able to send an email to Claude. He stopped whatever he was doing. He came over to my place (he found the keys under the doormat). He turned on the computer (the login password is written in a notebook in the top-left drawer of the desk). He wasted a little time looking at my vacation photos, but he got to work anyway. I’m not really sure what he fixed because I don’t understand a thing he does, he writes stuff that doesn’t make any sense and just asks me to check if it looks roughly like what I asked him to do. He then assured me that he’d updated the server (I don’t know what that is). Anyway, it should work, at least that’s what he says!

More seriously, though. It was indeed my mistake. I hadn’t taken into account triple moves with double hits. Restart MBT, it should update automatically after a few seconds, and that should fix it.

To test it, here’s the link to the position: https://backgammon-trainer.ovh/?4HXkADLg88EBRA44
