Stockfish evaluation is not the only criterion to determine whether a move is sound or not. The main issue with committing so early to 3.b3 (against this particular Black setup) is that there are no downsides to delaying that move. In other words, even if you want to play some setup with b3, there's no reason do it right now. Instead, other moves that ...

Against 1.c4. This will allow white to exchange their c-pawn for black d-pawn and later gain a tempo. 2. cxd5 Qxd5 3.Nc3, or 2...Nf6 at some point will be followed with e4 with tempo. All in all, white can take control of the center. According to lichess' database 1.c4 d5 is very rarely played. However, the move is probably not losing; stockfish gives it: 0....

The problem with 7... dxc3 is that White quickly regains both pawns. r1bqk1nr/pppp1ppp/2n5/2b5/2BpP3/2P2N2/P4PPP/RNBQ1RK1 b KQkq - 1 7 [StartFlipped "0"] 7... dxc3 8. Bxf7 Kxf7 9. Qd5 Kf8 10. Qxc5 d6 11. Qxc3 {+/- Sokolsky, ECO C}

The definition is still a bit ambiguous, but here's what I found. The absolute soonest to move the queen is probably the French Defense: Chigorin Variation which begins with 1.e4 e6 2.Qe2. The Scandinavian with 1.e4 d5 2.exd5 Qxd5 looks like the most common way to move the queen on move 2. I found a game by GM Aleksandr Rakhmanov in 2019 at standard time ...

There are 3 main reasons for this move to be inaccurate. It doesn't place any pressure on black's position. It weakens c3, allowing black to "force" your knight to the more passive square d2. It removes the Qb3 move, which punishes the early development of black's LSB. All of these allows black to develop more easily and equalize.

Chess strategy is complex and has several ingredients mingling at the same time. It is true that 3 c3 helps white mantaining two center pawns if black decides for a c:d4 pawn exchange. But black isn't forced to that and the move c3 has some incovenients. To list just two: blocks the c3 square which is the natural place for developing the Q-side knight; ...

The main function of a second is to provide timely analysis and advice to the principal player, both before and during the match. If the second is being pestered by the chess press because their identity is known then it becomes more difficult for them to do their job properly. It is an added unwanted distraction. Second, the second will have particular ...

Generally speaking, violating positional elements, at any time, is bad for positional understanding. When you win a lot of games with bad positional play, this provides positive reinforcement for playing badly. This opening, often called the Black Bear of the Philidor, isn't really breaking the opening principles. Black has gained space on the kingside, ...

It simply because With Black advancing pawns to both e6 and c6, the opening resembles a mixture of the Orthodox Queen's Gambit Declined (QGD) and the Slav Defense. (from wikipedia) If you consider that there are two components to the mainline Slav - protect the d5 pawn with c6 and then develop the light-squared bishop to f5/g4 - then the semi-Slav only ...

I'd say the opposite is true. "Principles" are great as general rules, but if chess were about following a set of fixed rules, you could simply buy a book that contains those rules and become a Grandmaster after you've finished it. But that's definitely not the case. Chess is a game of exceptions. Learning about this opening will help you find ...

It appears to be 4...Bb4+ that's the unusual move here. The chess.com database only shows one game with it, and that's the game that continued with 5.c3. When you have the position after Bb4+ on the board and it shows 5.Nc3 with a bunch of games, it's actually showing games that transposed into that position - the Nc3 was played earlier in the game. Given ...

This is an opinion based question as there is no way to know. For Bobby Fischer it might have been, but I met Bobby and know that he memorized all the openings. Would it work for you? My tournament experience says no. These days there are too many people memorizing everything along with all the better training for tactics than when I learned. Your more ...

Its evaluation drops form +2.3 to +0.0, so it considers it a blunder. Of course this does not match what a human understands as "blunder", but computers are incapable of identifying that. Your move is a perfectly reasonable one and if that's the biggest type of "blunder" you make in your games, you're on your way to a Grandmaster title.

5...Nxe4 leads to the Open Spanish. It's a respectable opening with some very long lines, as is typical of the Ruy Lopez. One thing it does not do though is win a pawn, because White can easily win it back after 6. Re1 (the main line is actually 6. d4 because Black cannot hold on to the pawn anyway). The knight is threatened and will eventually be forced to ...

The c4 square is a natural development square for White's light-squared bishop, which targets the f7-square. Having a pawn on c4 takes away that opportunity. In semi-open defences against 1. e4 the f7-square is shielded by a pawn on e6. But this creates dark-square weaknesses in Black's position when they have a fianchettoed kingside bishop on g7. So Black ...

This set up is often called "The Hippo", a possible reason is that bishops look like the eyes of a hippopotamus. For example: Eric Rosen: Don't Mess With The Hippo

Lichess also has several thematic tournaments throughout the week.

Alternatively you can create your own tournament with a ...

White is enjoying a space advantage in the center, but not anymore after ...Nxe4. It would be the "equivalent" of playing a ...d5 push, which unfortunately doesn't work in this position. White can reply to 1...Nxe4 with either 2.Nxe4 d5 3.Bd3 dxe4 Bxe4, which would leave Black with an at least equal position, or with 2.Bxf7+ Rxf7 3.Nxe4 which would ...

Fischer played a famous miniature in this line against Ruben Fine and published his analysis in "My 60 Memorable Games." Basically white gets a huge attack in this line and black's best shot is to give back all the pawns and pray for equality. I've included my analysis on this game in this lichess study. The actual (skittles, but still instructive) ...

This table can be thought of as a tabular representation of an opening tree of in-theory moves where the rows (y-axis) represent the flow of the game and the columns (x-axis) refer to variations/branches in the tree that can occur. The author in your quote indicated that 2...exf4 spans a family 24 variations/sub-variations that are noteworthy (and considered ...

Pirc in considered an inferior opening for black mainly because white gets more space and centre control. After Nxe4 Nxe4 d5 Bd3 dxe4 Bxe4, one pair of knights is exchanged, which negates the space advantage a bit (fewer pieces on the board, so space is less important). Moreover, the resulting pawn structure is what can be obtain from the Scandinavian, but ...

One should be very careful with the win percentage parameter. Probably here b3 was mostly played by lower-rated players trying to avoid theoretical lines and confuse the higher-rated opponent. Another example of the same fallacy: I don't remember losing in the exchange french with black. Of course, it's not because 3. exd5 exd5 is so great for black, it was ...

Don't try this at home. ;-) First of all, a simple LiChess search gives this is B12 Caro-Kann Defense: Advance Variation, Tal Variation, i.e. it has even a name and is legit. Second, 8 games listed, with IMs playing it, so it's still rare. Third, standard Black move is Kb8. He doesn't even try to immediately throw everything except the kitchen sink at the ...

The principle is to not bring out the queen too early when it can be easily attacked. In this situation there's no easy way for black to attack the queen on d4, so it's not too early. So instead of being a weakness, the queen in a central square is a huge strength. A very similar phenomenon happens in the following line of the Scotch game where white ...

If you're looking for something more common than the Scandanavian, then I think the Classical Variation of the Nimzo-Indian is the most common opening with a queen move on move 4 or earlier: 1 d4 Nf6 2 c4 e6 3 Nc3 Bb4 4 Qc2

There are many reasons why percentages are misleading. They can mean that the move is more often played when white is stronger than black, or in situations where a draw isn't what white wants, or there is a trap that many people fall into but that can be avoided, or lots of different reasons. Maybe it used to be considered good in the past until some novelty ...

Overall, I wouldn't suggest it, especially for a beginner. There are better ways to fight for an advantage. By playing e3 first, you are allowing your opponent to do almost whatever they like on their first move. Are you OK with them playing 1...d5? Is that going to prevent you from playing c4? If that's going to be a problem, you may want to play 1.c4 first ...

Using my free, open source pgn-extract program you can specify a grep-like FEN pattern to be searched for in a PGN file of games. The program comes with a file of opening lines (eco.pgn) so a search such as: pgn-extract --fenpattern "*/*/*/*/3PP3/2P2P2/PP4PP/RNBQKBNR" eco.pgn would output any matches along with the associated ECO information in ...
