The material balance is only temporary. After White goes c4, Black will lose a piece. If Qf5, White has f3 trapping the bishop. All alternatives to Qf5 leave a piece unprotected (for instance c4 Nxc4 Bxe4 Qxe4 Qxc4 +-) [Event "Chess Calculation: Chapter 1"] [Site "https://lichess.org/study/VFtoodiL/uG0A42Q9"] [Date "2021.09.12"] ...

I play the white side of this position often, and have an incredible winrate because to be honest, it feels very hard for black to develop naturally. Here's an example of how things can go wrong: [FEN ""] 1. e4 c6 2. d4 d5 3. e5 Bf5 4. h4 h5 5. Bd3 Bxd3 6. Qxd3 e6 7. Bg5 Qb6 8. Nd2 c5 9. c4 Qxb2 10. Rd1 Qxd4 11. Qb3 Qxe5+ 12. Ne2 Qc7 13. cxd5 exd5 ...

It just seemed obvious to me that gambits would work better with faster games, for the same reasons as given in the comments - it's harder to defend than attack, etc. I tried looking at several gambits in the lichess database to support this theory. In classical+rapid games, White wins 53% of Evans Gambit games vs 43% for Black. In bullet+blitz games, it's ...

By playing 11...h6, you created a weakness on g6, and you created a target on h6, now it is easier for white to open up a position around your king by pushing their g-pawn. White also has a potential bishop sacrifice on h6. In general it is best to avoid pawn moves in front of your king, especially when facing a pawn storm.

17

The sacrifice makes very little sense here. A weakness is only a weakness if it can be exploited, and in this case white won't really have anything substantial to go on after giving up the bishop. But why can I be so certain that white won't have any good follow-ups, even if I don't consider all possibilities? What aspects of the position make it clear to me ...

To add to the existing answers, you just gave up your light squared bishop for no apparent reason, while creating many light square weaknesses around your king with the same move! Now white is the only player with a light squared bishop and you will have a tough defensive job if white plays correctly.

Why is h4 much better than h3? It's very simple. The prospects for the bishop are much better on g3 than h2. On h2 the bishop does nothing useful and it will take a lot of moves to get it back into the game via g1. Black will exert iron control over f4 with pawns on e5 and g5 making the freeing move f2-f4 impossible. On g3 the bishop has a role protecting ...

Is his rating a limitation to teach me? No. As I say in this answer, "you are too fixated on rating". High rating does not guarantee coaching ability. Low rating does not preclude coaching ability. Today the guy in our club who does the most coaching is rated about 1900. 50 years ago, the first time we played for the same club, he was rated about ...

It might be not even as simple as the other answer suggests (regarding only objective evaluation), as "both lines are (roughly) equal" is probably already from a certain perspective. Let's view it specifically from the computer and the human eye and that we want to win the game. I outline only the central points. Computer, Variant 1: "I'm an ...

First, the human assessment: White has the advantage of his figures being already developed (Rxh7 is always to consider), but is saddled with a king that is in grave danger already after the natural e5. (To underline this: Black to move seems to have a clear win, placing the wK on e1 is a clear win for White.) The position thus is tactically "red-hot&...

It's not so simple. 1. Bf3 leads to a position where White is up an exchange. 1. Rb6 leads to a position where White is up two pawns. Both are worth roughly the same in terms of material. Look at the lines carefully: After 1. Bf3, Black does not have to play Bxc6. 1...Rxc6 2. Bxc6 Bxc6 -- White is up an exchange. After 1. Rb6 fxe4 2. Nd8+ K-wherever 3. ...

Calling it an "inaccuracy" is nothing more than the engine saying that it evaluates the position after one move to be a certain amount better than after another move. It doesn't necessarily mean a move is "bad". Both d-pawns cannot be kept no matter what Black does. After 1...Ne4, if White plays Nxe4, the recapture will leave the c4 ...

After 10.h4 g4, the kingside pawn structure is more favorable for White. Black's g- and h-pawns are blocked, they are too far advanced and feel more weak than strong. Black doesn't have possibilies for a kingside attack because of the blocked pawns. White's king will be safe on g1 after castling short. This is the most important factor. Far advanced pawns ...

This won't work. When you make aggressive piece sacrifices like this to expose the enemy king, you need to be able to follow up. In this case the obvious follow-up moves are Ng5 and Qh5, but both g5 and h5 are protected by Black's pieces. You could try f4, but it's slow - Black is not obliged to capture and after [pass] 2. f5 Bf7 you are once again out of ...

White has easy ideas like 1. Nxe6 fxe6 2. Bxh6 gxh6 3. Qxh6 with ideas of Rh3 to g3.

4

This is a quite complicated position. It's not about "following a strategy" but rather about concrete calculation of different lines that could arise. Any "tiny" mistake by either side can lead to a huge change in evaluation (for example, White is threatening checkmate right now). Most players would prefer to have White here, since ...

black's king would be totally exposed if white's bishop decided to take the pawn Having little pawn cover and being "exposed" are completely different things. Black has five pieces available for the defense of their king, while White has only four pieces available to attack. One of those pieces is the bishop whose sacrifice you're evaluating, one ...

The position you give looks like you have developed your pieces to suit the Carlsbad pawn structure where black has pawns on b7 and c6 instead of b6 and c5. So, the first thing to say is that you probably need to be less formulaic in your opening moves. You need to react to how your opponent is developing their pieces and place your pieces accordingly. For ...

Josh says f5 ... Is Josh wrong about f5? Yes, although black's position is terrible in any case. If we look at the initial position and try and assess a number of things are immediately obvious: White has a lot more space All the pieces and all the pawns are still on the board We can also say: White has completed development Black still has several ...

Is there any broad-brushed strategy for either side that would gradually but decisively achieve victory? Sounds like what you are really asking here is "Can black survive long enough, without giving back too much material, to take advantage of the extra material to win." That's because white's winning strategy would have to be to checkmate black ...

2

It sounds like you want a more concrete answer than "your light squares are now very weak", "white has the bishop pair", and "you've just created a hook for white to utilize by pushing the g-pawn to g5 [and you likely won't have h5 as a response]". Obviously your engine can give you the most concrete justifications, but I would ...

If we see from black prospective its pieces don't have a clear plan.For me as a player from black side I will try to bring the other rook on the king side. So as to defend the position strongly because black knight and bishop are having very less squares on the other hand white will bring his other rook on the king side with castling.Pushing those king side ...

Stockfish just tells you that both moves win. The exact evaluation is irrelevant; if you increase the depth, I'm sure the evaluation will go up. There is really no need to overthink this. For example, if you're up two pieces, it might be a good idea to give up one but make sure the opponent has no counterplay, as opposed to keeping both and allow a few ...

My computer likes the cowardly Kd3 putting the king safe, which made me laugh. It's second favourite move was d6 which has more of a point - fight for the center and let the bishop see the f7 pawn directly. Also after d6 then Qd5 would threaten mate on f7. To my carbon-based eye h6 looks attractive. The cunning point is that the white queen eyes the ...

2

My approach: Black stands terrible, and h6 like you suggested is the only chance to muddle waters as a rook line against the white king is opened. And in this variant, I would rather let the Bh3 live for now: It's rather a liability with the pin than the rook giving a plain check. Also, White threatens h6 followed by more pawn moves, which would completely ...

As Hauke Reddmann wrote in the comments, the answer is "it depends". It's not a problem until you need the pinned piece to move. In this game, your knight wasn't pinned after 6...Be7, but you proceeded to "self pin" after 8...Qb6 and 9...O-O. Even this wasn't a problem because you didn't need the knight to move. It did mean you can't play ...

I think more typically the idea is Kh1 and then Ng1 to get the knight out of the way of the f-pawn. Karpov has historically displayed a very fine "feel" for where pieces are best placed, so while I wouldn't rule out the blunder or surprise factor explanations right away, I wouldn't be quick to embrace them, either. A typical usage of the Nh2 is ...

Ok so as I said in comments: It looks like white is computer-winning, but the position is very sharp. See for yourself on lichess stockfish. No idea if this is human-winning (ask Hauke Reddmann). But it appears white pretty much has to do as follows to win. It appears white has a few drawish options but even fewer winning options. [FEN "rnbqkbnr/...
