what is the most popular losing opening?

[Uri Blass]

possible candidate is the opening 1.d4 c5 2.d5 e5

I do not know if white is winning but stockfish gives more than +1.5 for white

It is possible to check by engine-engine games if white is winning.

If somebody can rank positions in the opening based on popularity and play engine-engine games we may find the most popular line when stockfish-stockfish game is not a draw.

[reflectionofpower]

I play this opening exclusively all the time as black and I have a 55.6% win percentage. It is a tight, hedgehog formation but I always get good chances on the kingside. I feel comfortable playing it. Some players play these wacko openings and they do good with it because they are used to the formations,motifs,etc.

[Uri Blass]

humans player may get good results from losing positions.


The question if objectively white is winning after 1.d4 c5 2.d5 e5 or not.

I think that we can learn from results of stockfish-stockfish or stockfish-lc0 or stockfish-dragon games at long time control.

If somebody can rank positions in the opening based on popularity and play engine-engine games we may find the most popular line when stockfish-stockfish game is not a draw.

Let’s start with the Barnes Defense (1.e4 f6):

The Barnes Defense has a close cousin which is even worse: the Fried Fox Defense (1.e4 f6 2.d4 Kf7):

There’s also the Grob (1.g4) which has had its own quirky enthusiasts over the years. It is named after the late Swiss IM Henri Grob, who used it semi-regularly in his own games with some success. It critically weakens squares which may become important on White’s kingside.


At the beginner’s level it makes no sense to study openings (in depth).

It’s ok to know the first moves, which is what defines or characterizes the opening, but to study all different variations, many moves deep is not necessary at beginner’s level. Some people even argue that it is only worth around 2200–2400 level. Although that is debatable.

For instance, we know that the Spanish Opening (Ruy Lopez) is defined by the following moves:

e4 e5
Nf3 Nc6
Bb5
Black can answer in many different ways:

Morphy Defence 3…a6.
Berlin Defense 3…Nf6
Bird Variation 3…Nd4
Schliemann Defense 3…f5
Etc
White can also respond with many different moves, each one of them taking the game into a different route.

After 3…a6 white can respond with 4. Ba4 or Bxc6.

Each move opens a new branch and you can see that the decision tree is becoming wider and growing exponentially.

So, you have memorized 118 different variations until move 15 to gain a little advantage or at least not blunder. What then? What to do in move 16? You don’t know, you haven’t studied that!!! Chances are that you’re going to blunder your bishop in move 19 if you don’t know what you’re doing.

And that’s the key.

At the beginner’s level there are many aspects of the game to learn, from tactics, strategy, positional play, defensive play, how to attack, openings, etc.

I assume that you’re like everybody else and you don’t have infinite time to study chess so you have to prioritize.

Learn chess fundamentals first, invest most of your time in tactics. Little by little you’ll know more about the game and the opening study will yield better results.

The most important about the openings are the general principles (for the first 8–10 moves)

Control the center
Develop your pieces
Castle
Protect your pieces
Don’t move the queen so early
Connect your rooks
Don’t move a piece twice
So, learn the first 3 to 5 moves of some few lines (and the idea behind them), do a lot of tactics, study the endgame and play!

By knowing the most important general principles no matter what you are facing something weird that you have not ever seen before for instance when you take Rook Odds the engine will throw opening that you would have never expected or memorized in your lifetime, but by knowing the general principles and applying them you can survive the first 15 moves and knowing that when you are ahead in material all you have to do it to force the trade of more pieces in every opportunity that you get. Let me show you a game that can demonstrate this.

e4 f6 is not popular

I find only 30 games at all levels based on
https://old.chesstempo.com/game-database.html

g4 is relatively more popular because I find 1123 games and if I look at 2200+ level I find 159 games
The line d4 c5 d5 e5 is more popular
I find 4311 games out of them 1890 are between players above 2200.

[Uri Blass]

After d4 c5 d5 e5
I get the following analysis

3.e4 gets the score 1.5 for white

[Peter Berger]

possible candidate is the opening 1.d4 c5 2.d5 e5

I do not know if white is winning but stockfish gives more than +1.5 for white

It is possible to check by engine-engine games if white is winning.

If somebody can rank positions in the opening based on popularity and play engine-engine games we may find the most popular line when stockfish-stockfish game is not a draw.

I have a hard time believing 1. d4 c5 2. d5 e5 could be a win for white. A forced win isn't availlable as far as I can see, and the structural advantage for white seems too little to me.
I +do+ think that 1.d4 d5 2. c4 Bf5 could be a win for white though, or more like a 0.75 for white.
I used to play this with black and knew the lines very well. One day I played an old-aged IM in the league, the game went like 1. d4 d5 2. c4 Bf5 3. Nf3 e6 4. Nc3 c6 5. Qb3 - he even went like e3 in one of the next moves. To some extent this is a dreamline for black - a Slav with the bishop out, what better could you dream of? I felt pretty confident but lost the game eventually. In the post-mortem I was looking for my tactical mistakes in my good position.
My opponent was gracious and took some time to explain the mistakes in my reasoning as he saw I was genuine - so a free chess lesson for me, an impressive one I may add. He made the point that I can reach my "ideal" setup, but then there is nothing much else I can do while he has lots of additional useful moves he can make. I later checked his comments with engines of that time, I came to the conclusion that he was right and gave up on 2. .. Bf5. This +=/+ over - can be too much to overcome.
These days Stockfish teaches us similar lessons, but it can't tell its reasoning quite as well.
I an a little German computerchess board, someone made the point that the Caro may be a win for white based on high Stockfish evaluations. While this may even be true for the Nd7 lines, I can't believe this to be true for the Bf5 ones. You just have to go along with Stockfish suggestions for a little longer to realize that its evaluation will drop heavily eventually and humans were right.
But how to tell the difference when it is not just about tactics? Spending time helps some, but I wouldn't rule out that Stockfish in fact has killed +many+ more openings than most think possible.

[Uri Blass]

1)For the caro the question is what is the relevant position.
It does not seem stockfish evaluates 1.e4 c6 as a big advantage for white.

2)1.g4 is considered a forced win for black and stockfish does not see more than a score near +1.5 for black even after a long analysis so scores like 1.5 are scores to suspect a win.

Lots of openings are playable at the club level and some dodgy ones are used occasionally by strong players for surprise value. But computer and correpondence play have made a lot of suboptimal lines very risky. I think the Caro-Kann Advance for example is quite challenging for Black. Same with the Scandinavian. If Black is very well booked up he might be able to steer into a variation where he is not too bad. But there are lines that are virtually losing against a silicon opponent.
