What is black’s compensation in the main line of the Caro Kann?

At a basic level, what we want from an opening and a defense, is: we want to be fighting for the center squares (1), we're trying to develop our pieces and get good squares for them (2), and thirdly, ...

In Bb5 systems against the Sicilian, why does White exchange their b5 bishop without playing a6?

Some things that are probably part of the answer, but probably not complete and concrete enough: 1...a6 won't come. There is no threat to a pawn on e5, the knight isn't pinned, the only point of 3....

Development problems for black after f4 in French Defence

You're playing a very sharp opening line that only works thanks to the option of playing 10...g5!. You should only enter this type of position if you're aware of what you're doing. Otherwise you'd be ...

Why black is happy with slow development?

I do not know that I would say "happy", but in chess, there are pluses and minuses to every move we make, and on top of that, there are exceptions to many positional concepts. We see GMs move pieces ...

What is black’s compensation in the main line of the Caro Kann?

The main reasons it is OK for black is that he is still down only one tempo in piece development, but he has traded off his bad bishop for white's good bishop, and his position is still very solid so ...

Skill degradation

During the epidemic I didn't play for 2-3 years. Before I stopped I had Lichess blitz rating around 2000, after I resumed my rating fell to 1600. Mostly due to missing simple 1 or 2 ply tactics. To ...

Developing the king before developing most of your pieces

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, ...

In Bb5 systems against the Sicilian, why does White exchange their b5 bishop without playing a6?

A few things: 1) White's actually not wasting any tempi. He has to move his bishop out anyway (in order to castle). Then, once on b5, taking on c6 doesn't waste a tempo since Black has to spend a ...

How good is 1. e3 2. c4 as an opening for White?

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 ...

Why develop knights before bishops?

Commitment (versus flexibility) indeed is the main reason for this piece of advice. In particular: The first moves are (usually) all about fighting for control over the center. The knights are ...

Development problems for black after f4 in French Defence

I am pretty sure the first 10 moves are pretty ok, but after Kg2 you are supposed to play either 0-0 or g5 (maybe some other moves are fine too; fxe fxe 0-0 is also not too bad I suppose), but Kf7 ...

Petrosian's 9. ... Be7 10. ... Ng8 11. ... Bf8

9 ... Be7 is a normal developing move preparing to castle next move. 10 ...Ng8 reflects a change in plan given white's change to the pawn structure. On f6 the black knight was doing a good job ...

Why develop knights before bishops?

Another reason besides what you stated: The Bishops can work from home. What I mean by that is when the e/d pawns are out of the way the Bishops are already influencing enemy territory.

Polish Opening development

The line that you refer to is probably 1.b4 e5 2.Bb2 Bxb4 3. Bxe5 Nf6.. I recall some early opening books saying that this was a bad defence because it surrendered a center pawn. The more modern view ...

In Bb5 systems against the Sicilian, why does White exchange their b5 bishop without playing a6?

A lot of it is simply to create an imbalance. Nakamura has mentioned this before about a different opening B-for-N trade, and sometimes it is done without even getting doubled pawns in return, like an ...

In Bb5 systems against the Sicilian, why does White exchange their b5 bishop without playing a6?

The main reason is that White does not want to face Nd4in many lines. They want to make sure they will "hurt" Black's pawn structure with Bxc6. Compare this line with others where the Black knight is ...

When and why is it good to deny the development of White's dark squared bishop in the Caro-Kann exchange variation?

The 6...Bxf3 tactic wins the d4 pawn by removing its defender. Sure, it gives up the two bishops to do so, and that's the reason why black's not a full point up in evaluation. But that's not enough ...

When and why is it good to deny the development of White's dark squared bishop in the Caro-Kann exchange variation?

I add another answer since the crucial point hasn't been addressed, methinks. Indeed, after 6...Qc7 7.c3 it's a simple transpose and any decent algorithm shouldn't depend on move order to the position....
