[FEN "r3kb1r/ppqn1ppp/2p1pn2/4Nb2/2BP4/2N5/PPPBQPPP/2KR3R b kq - 0 10"]

This position is taken from super GM game, so I am fully aware that Black might be busted here and that this question might remain unanswered. Please try to post only relevant comments and answers, i.e. ones that demonstrate a path to equality for Black.

    What game is this from? Whose move is it? Why is your diagram upside down? And why are you ordering me not to comment unless I can answer the question? Comments are for the purpose of clarifying and improving the question, not answering it. – bof Mar 19 at 22:09

    @bof Black to move (which is why it's upside down, I think.) – D M Mar 19 at 22:59
  • @bof Black to move, hence the upside down diagram, use game Popov vs Grischuk World Rapid 2019 as a reference, I am not ordering, just politely asking to not spam (asking for clarification/improvement is not a spam). – AlwaysLearningNewStuff Mar 20 at 7:32

First, black is hardly busted here, and Stockfish 11 confirms this with both 10...Be7 and 10...b5 being 0.00 at a depth of 30. 10...Bb4 is also reasonable. That said, as I force in the moves it believes are best, it eventually sometimes thinks white has a slight pull, which is not surprising given the clear space advantage. At the same time, in practice, per the Mega 2020 database, the white wins 72.3% of the time from this position, so unless you play like a computer, you still may lose, and there are a virtually infinite set of possibilities for white to play while black is walking a fine line all the way. This is a line I would try to avoid in practice, and keep out of my repertoire as a matter of course.

I do not play the Scandinavian, but I have played the Caro-Kann for a long time, and this is very similar to one of the main lines, and what I can say about both is that white has more space, and that is not going away for a while, and thus this is always a little uncomfortable for black...a typical plus-equals position. In both, black must finish development, especially securing the king here since it is vulnerable to tactics, and then eventually break back with c5. Other times, it ends up an opposite-side attack.

Most players here have played 10...Nxe5, which is horrible from both a Stockfish perspective at +1.3, and a winning percentage perspective at 82.2% for white. It is not a good move in a practical game as it solidifies white's space advantage with tempo, and puts the Bf5 at risk immediately to 10...Nxe5 11. dxe5 Nd5 12. g4 Bg6 13. f4 with a solid advantage.

You cannot get a 100% answer to your question as it is too early in the opening to say as it is with virtually every reasonable opening where white has a small space advantage. It will always feel like white has a small advantage until it eventually levels out...or doesn't. That is chess.

This is very close to equal, and super GMs would hold it, so the way I would play it is the solid 10...Be7. After that, there are basically two plans for white. To move the Bc4 to b3, playing prophylactically, or to play Rhe1, and eventually expand on the kingside.

There are an incredible amount of possibilities here, but this will give you a place to start.

P.S. In a position like this, and this one is not unique, there are so many reasonable lines that it is unclear which is best for the stronger side, and thus, there are literally millions of possibilities from the moment you play 10...Be7 in just the next few moves. In cases like this, now that you have a place to start, you will need to spend a lot of time on your own with a computer not just to get a few more specific lines, but also to get a feel for the plans and move orders that may occur. Since you cannot possibly memorize every possibility, you are almost certainly going to end up on your own sooner than later, and what you need to develop is a sense of HOW to play the position correctly.

    @AlwaysLearningNewStuff I did not add a lot of lines to keep it simple, but I just spent 90 minutes analyzing with a computer to get this, so whether you think this is enough, or not, I was going to post it. At least, please do not downvote it. – PhishMaster Mar 19 at 22:40

    +1 from me :) Thanks for the invested work. I am preparing for a tournament where I will face 2500+ ELO competition, I can not afford to fool around in the opening. I like the line, but in all the continuations plan with h4 simply busts Black. That is why I have asked here for help. I will carefully go through the lines and leave a reply. Thank you again for the invested effort. Regards. – AlwaysLearningNewStuff Mar 20 at 7:27
  • OK, I have gone through your lines, they are equal. Black will easily equalize indeed. My problem is that online engine, which is not so strong, claims that h3 + g4 pawn storm refutes this line. Is it possible for you to investigate that plan? In your main line, White could try f3 with g4 next, I guess... Again, thank you for all the invested effort. I am analyzing myself, when I have time, so it might take a while before I get back, but do not worry, I will not forget this question :) Regards. – AlwaysLearningNewStuff Mar 20 at 7:56
  • @AlwaysLearningNewStuff Could you please be specific and reference the line and move number that you want to try h3+g4 or f3+g4. I am also going to add another general paragraph about positions like this to the answer for general guidance. – PhishMaster Mar 20 at 10:28
  • At move 11, White goes Bb3/Rhe1 but I like what I get from those lines. I was wondering if 11.h3/f3/h4/f4 thrusts work, because engine suggested that this plan demolishes Black. It was opening explorer at Lichess, you can turn on computer analysis while browsing through the opening. I do not fear the other lines, I have good understanding, only those concrete pawn storm fear me, because I have no good machine that I can use for analysis. If there is no clear refutation, and unclear/equal position can be reached, than I would be fine with it. – AlwaysLearningNewStuff Mar 20 at 13:07
