Opening Inaccuracies Tool

This hits harder than most “opening prep” content because it attacks habit, not theory. Everyone knows engines give better moves , almost no one tracks the slightly-bad ones they repeat out of comfort. Turning opening mistakes into patterns instead of one-off sins is exactly how real improvement actually happens.

Very solid idea, and refreshingly honest in intent

Thank you, it is a decent first attempt I think.

One day a prodigy starting with the benefit of all technology will reach his prime and beat every engine and it will be cool to witness.

I wish I could believe that, it would require a god tier genius, but even that probably won't be enough, engines currently outrank humans by more that 1000 elo...

Rare feats of uncanny phenomena suggest it is within the scope of the human mind and body. God tier genius is easily expected in a great outpouring and final demonstration of God’s Spirit.

If we want to fix our opening inaccuracies, we need to memorize the undisputed mainlines. Practicing mainlines helps broaden our understanding of them. I often need to place a few pieces before realizing it's impact. Like in correspondence chess, I backup the moves and move them forward again just to put me back into context of what I had originally planned. So recommend doing the same with the following openings. Play them out, back and forth until the pattern runs in your mind, like deja vue. https://lichess.org/analysis

In the starting position the engine analysis shows that PV1 and PV2 both have the same +0.2 value.
When memorizing engine mainlines, make it simple to start with and look at those cp values that are similar and disregard the rest until you are familiar with what you have memorized.

(+0.2) King's Pawn Opening: 1. e4 e5
(+0.1) Ruy Lopez (Spanish Game): 1. e4 e5 2. Nf3 Nc6 3. Bb5
(+0.1) Italian Game: 1. e4 e5 2. Nf3 Nc6 3. Bc4
Note: The above move (3. Bc4) is a PV2 variant. It does not have the same cp value as pv1 (3.Bd5).
So you might want to look at the popularity of a chess move.
https://lichess.org/opening/Kings_Knight_Opening_Normal_Variation/e4_e5_Nf3_Nc6
If you clicked on the link, you will discover that Bc4 is more popular than the engine recommend PV1 line Bb5.
So when you see two PV lines with the same cp value, look at the popularity of the move and memorize the one that is most popular, because it's going to be used the most. Sooner or later you will prep for an opening and purposely do an inaccuracy to leave the mainline. This is where the others that have not memorized that variant will become unfamiliar and might of premoved the wrong move sequence. This helps to see if you are playing an experienced player in all variants or just a fast player playing mechanically with premoves.

Continue with the rest ... Label the PV# and the cp values so you can discover which on has the highest cp value.
[+0.3] 1. e4 (PV2) c5 (PV3)

English Opening: 1. c4 e5

Larsen's Opening: 1. b3 e5 2. Bb2

Do you think the Stockfish engine will ever start with g3 ... I think it will always move according to it's programming.

I have been unable to get the tool to work. It ran yesterday for over 5 hours, spending the last 2+ hours at 99% complete, but returned nothing. Tried again overnight. The tool ran for 12 hours and was on 74% complete when I stopped it. Any ideas or suggestions?

Lower the settings as much as you can and see the result. Then increase one of them .Find the balance for your computer.
This is why I mentioned my cpu and said how long it took. What was your computer running on ...

Inaccuracies are easily understood by PV lines, but really clear when we see things like this in end games.
Mate in #-13

PV1: #-13 24. Kf1 Ng4 25. ...
PV2: #-12 24. Kh1 Ne5 25. ...
PV3 #-10 24. Kh3 Ne5 25. ...
PV4: #-8 24. Kf2 Ng4+ 25. ...
PV5: #-7 24. Kh2 Ne5 25. ...

It's not so much inaccuracy as it is a waste of time to complete the game faster or trying to avoid the inavoidable conclusion. Sometimes the scenic route is best and safer than the faster routes. A GPS offers a few different ways to reach your destination. With chess engines, there is no way to prove that the Principal Variation (PV) like PV1 is better than the PV2 or PV3, especially when all three have very similar cp values. One could be less sharp and take more time, but in the end there is less risk of losing the initiative or even blundering, because the depth required to play-out that line is less. Well at least that's my assumption of how to approach what engines call inaccuracies.
