Haven't checked, but I would guess it is due to a combination of weaker players (the classical Scheveningen is not all that popular nowadays), most games being blitz or bullet and the move not being o …

The first thing to learn once you know how the pieces move is basic tactics and general strategy. Tactics: In certain positions it is possible to gain an advantage doing a certain move or sequence of …

I don't think it is possible to forcibly mate the king with rook and knight only. Proof: The only mating position is with the white king in a corner, the rook giving check from an adjacent square a …

In my view a chess opening is characterized by a typical pawn structure and plans associated with it. As such a single move like 1. e3 should not deserve to be called an "opening' because there are no …

Depending on whether occupied squares need to be covered as well, the number is: [Title " 12 knights, Without Covering Occupied Squares"] [FEN "8/5N2/1NN1NN2/2N5/5N2/2NN1NN1/2N5/8 w - - 0 1"] [ …

There is no general rule for multi-pawn endgames as they are much too complex. However I believe that most of the pawn only endgames that appear in regular games are readily assessed correctly by gr …

From a human, chess player perspective, space is something you talk about in opening/middlegame (rarely in endgames), when there are many pieces on the board. In most normal openings it is typically d …

Two things could be meant by space: White has more space (basically one row more than black) to maneuver his own pieces behind his pawns, let's say around d2, e2, d3, e3. Compare this to black who h …

There are all kind of endgames, so it is a bit difficult to generalize, but still there are a few things that are relevant in many cases. Just like in the middle game you can evaluate the position ba …

In the Sicilian Najdorf poisoned pawn variation what is the difference between including the moves 7...h6 8 Bh4 (as many top players do) and not including them? [FEN ""] 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4. …

Not sure whether this is more of a physics or a chess question. Looking at the evaluation graph (computer evaluation vs. move number) of a game of chess, I realized that there are some similarities t …

Opening theory refers to particular variations; but also to typical plans specific to the respective openings. … So perhaps at one point in time, "opening theory" was a lot more based on principles and less concrete lines!? …

chances, particularly against f7 (with a bishop on c4) and on the open c and d files (after putting rooks on c1 and d1 potentially (depends on the opponent) playing off-beat openings like this can avoid theory …

In my experience, your second idea, sinking a knight in g6, is not very common. Some more ideas: piece sacrifice on h6 for two pawns and an open king piece sacrifice on g5 (not forced but tempting) …

Yes, all KQvK positions are won under these conditions (no stalemate, no capture). The same holds for KRvK. The only possibilities for such basic endgames not to be won under your conditions would b …
