Analysis Glitches

I tried to analyze a game on mobile today but the report had errors like showing the wrong moves and then crashing after a few moves in. This has happened before but I don't remember the outcome of my last post. Here are some screen shots. As you can see the moves played do not match the analysis response.

The board shows the game moves. This is intended.

Look again. Bishop to e6 is NOT knight to f6. Nor is pawn to c5, knight f3. If so, that's one scrambled board  After a few moves into the report the app just crashes.

Of course Be6 isn't Nf6.

But Be6 was played, not Nf6. Same with c5/Nf3.

The board shows the game moves, not the engine suggestions. Is this really so hard to understand?

Evidently. I suppose it crashing is also intended?

No, I'm not confused about the differences between the moves and the feedback. What I'm saying is the feedback is the wrong feedback for the given move. My app is being buggy so I'll just do a screen shot from the computer.

In the above shot, d4 was played and the feedback given is about d4. In this case d4 is a book move, and then there's a line of suggestions.

In the previous examples, the feedback given has nothing to do with the move played. You could argue that it's "suggesting" Nf6 when Be6 was played, but it's not being presented as a suggestion. At least, not in the way the app has trained me to interpret its feedback.

Here's another example: This is the same game from my initial post analyzed on the computer instead of the app. Like before Be6 was played and look at the feedback; it's about Be6. It doesn't talk to me about a move that wasn't played.

And here's the other move: c5 is played and the feedback is about c5, not some other move that wasn't played at that time, like...I don't know, Nf3?

Normally, the feedback between the app and the computer is consistent -- albeit, the computer gives a deeper analysis. But every now and again, I get this weirdness where the app is giving feedback about moves that weren't made and the app crashes after a few moves in. Is this really that hard to understand?

I'll try it once more:

The app does not give feedback for moves that weren't played. If the app displays e.g. "Nf6 is a book move", then this is feedback for the played move, here Be6. You may read it as "I don't know about Be6 but Nf6 is stored in my opening book."

A reason why the web analysis behaves differently wrt book moves may be the need to save power on mobile devices.

I can't help with your crashing problem, just one suggestion: try to run the analysis on your mobile in the web browser. If the problem persists it's likely to be a hardware problem; else you may want to re-post in the Help&Support subforum.

HTH

You're right, the app should not give feedback for moves that weren't played. But it did. You can see it clearly in the screen shots of the original post. It's a glitch that leads to the app crashing.

Here are some shots of the app from the same device of when it's working correctly:

As for it being a hardware thing...that's possible, but this has happened to me on more than one device. A more likely culprit is a memory leak caused by an out of bounds array. The question then would be, "Under what circumstances is this reproducible?" so it can be solved.

FYI, your condescending tone is not helpful. And to say that the app "does not" do something -- which is an absolute statement, by the way -- is a clear indication that you're not a programmer.

I posted here to see if anyone else had experienced this. Again, it doesn't happen all the time but it has happened to me a few times across different mobile devices.

I will see about posting in the help/support section.

Can I see the link to the game?

I have only used a laptop, never an app. From what I can see, however, the program certainly seems to be doing something wrong (weird). I didn't look at all of the images, only the first two. While the image of Be6 matches the move, and Be6 is a Book move as shown, I don't know why the screen would show Nf6 at the top. That does seem strange. Same with the second image, picture and description don't match. Very strange.

As noted, I don't use apps, but I can't see of any way to get the analysis to show what it's showing on any app. As you noted above, it's probably best to submit an error report to see what's going on. Good luck.
