Computer Analysis of D4 Nf6 line

Hi,

My kid is having a bit trouble against d4. He was responding with g6 to d4 by choice and I am not fan of it. White pawns advance too far limiting the development options of black. It is not easy to play and he has had subpar results against lower rated players. He is at 1500 ELO by the way, 8 years old. Recently I managed to convince him to respond with Nf6 to d4 by promising that I will have the lines analyzed until black castles. Since then I have been letting stockfish run and find the best moves for black for different moves white can make. And I have been recording them in a pgn, also noting down stockfish evaluation of each move.

The goal of this study was to discover simple things about d4 actually.. Like under which circumstances we let the light bishop move out of the pawn chain. In which circumstances we develop the dark bishop to e7 g7 or g4, or when to Nbd7 when to Nc6, move order etc. To let him survive the openning and fight on equal grounds for the rest of the game.

However this has proven harder then I tought. I am having stockfish find the next 5-6 best moves by white after each move by black. As for black, I am having stockfish find the best responses only. The number of variations have quickly escalated to a “hard to manage” level. And it takes time as well as I am having the engine run until depth 30 minimum.

So the first question is, would there be such a pgn somewhere on web.. Not just the variations, but also with the computer evaluation of the position for each variation. Like this position is +0,20 at depth 30, this position is -0,10 at depth 30 etc.

The second question is, how much sense does this study make to you? I had done a similar study about Scotch gambit and the kid is playing scotch comfortably now with good results, however Scotch was easier becouse some responses by black are plain bad, you dont need a computer to tell you that, and hence the number of variations were somewhat managable. D4 being a positional game, it just doesn't seem like the responses by white have a tendency to narrow down, even moves like early a3 or h3 does not seem to deteriorate the position for white.

Thanks,

I know this is not what you're asking for, but why not choose an opening that is already well known like the KID? Books like Bologan's King's Indian contain a really complete and well explained repertoire.

Why the King's Indian? The OP implies he doesn't like playing with a space disadvantage so this isn't what I'd recommend

Well, my reasoning might not be valid as I don't have much experience with chess. I am just trying to learn to help the kid. That said, we are not focused on opennings. I just want to learn and show him how to achieve a playable position against d4 for all the followup moves white can come up with. We study like 2 hours per day on average and we probably spend less then 1 hour on opennings per week. I wouldn't want us or myself going through an openning book. I am just trying to get him to have a playable position against d4 and a pgn with all lines along with engine evaluation of the positions made sense for this purpose. 

If you want a playable position against d4 an opening book is far easier than using engine evaluations which are pretty meaningless anyway in the opening. Why do you not want to use an opening book?

Not  untypically what DeirdreSkype as posted is really helpful. Can support the suggestion with this thread https://www.chess.com/forum/view/game-analysis/my-first-chess-tournament-in-canada  were a a player apparantly inexperience in OTB play is using the Queens Gambit Declined to good effect.

This player uses untheoretical and probably objectively not best ideas like developing Na6 in Tartakower QGD, but relying on the opening basic solidness to learn how to play typical QP pawn structures.

Your story of trying to use software to prepare openings for an young inexperienced player is a very  bad idea. 

 Doesn't 3...Bb4 4.a3 Bxc3+ a favorable version of the Saemisch Nimzo Indian for White? The pawn on d5 it's strategically useless for Black's concession of the Bishop pair. White's didn't even commit e3 yet...

4...Be7 its an Alatortsev with missing tempo otherwise.

You lost me there.. I assume what I am looking for, does not exist.

It looks to me that Fischer's novelty dealing with the Winawer 6.a4! is quite testing for the modern idea 5...c6 too. 

It does not - you'll need an opening book to get the explanations you want.

Sedat book is one of the best computer analysis opening book. All lines are tested with 3300-3500 rated computers, with 1 billion games. 

However, I personally dont recommand for those who dont have tactics rating <2000 cos 99% of computer lines are based on tactics and it will be very difficult to understand for beginners.

Thanks for all the feedback.

Imo, g6 is definitely harder to play then d5 or Nf6. White creates more threats, accurate play required for black for a long while to equalize the position on the board. That is my takeaway from his games. One subpar move and he goes into trouble. By the way I am not asking him to do anything without understanding the ideas behind. We came a long way. Last year in January he was at 1100, he got 400 points in less then a year. He is in top20 in country in his age group now. National championship is closing in, two months left. We are trying to fix whatever we can in the remaining time.

We have looked up the systems recommended here and some others. Semi-tarrasch appealed to him, he likes to play open games, he needs room to move, gets bored in slow games. So I am going to study this and try to handover whatever I learn. Checked out Sedat book as well btw. But couldn’t figure out how to benefit from that.. It is probably for more advanced players. Thanks,
