This position is a draw, the game is over. It is not possible for either side to checkmate the other from this position, not even if the side with the bare king would try to help. The same is true for king and knight vs king. A single knight or bishop without any pawns or other pieces is not enough to win the game. With king and two knights vs king it is in ...

I always like to explain this in a visual way. Basic Idea: Keep the bishops together. They form a large net (restricted area) from which the opponent king cannot escape. Step 1: Push Opponent's King To Edge Rank or File Keeping the bishops together and using the king for support, make the restricted area smaller to push the opponent's king back to an ...

Actually, the bishop and knight mate is not as slippery as it appears. I have checked this on a tablebase program I wrote. On a 10x10 board, the side with the bishop and knight (say white) can force mate in at most 47 moves. White can even force mate on a 16x16 board, in at most 93 moves. I believe mate can be forced on an arbitrarily large even size ...

It is a fairly short and simple explanation: They can combine to attack any square, not just squares on one color. As part of that they can also shift the attack better from one square to another.

it's a bishop for knight in my favor So what? You will have moved the knight 3 times to your opponent's bishop 1 move and you will have improved your opponent's position by opening the f file for him. So, not in your favour after all. the bishop makes my position slightly vulnerable because of the pin on the queen No, it doesn't. If it ever becomes a ...

In the diagrammed position you have a material advantage but Black's position is a little bit better because his rooks are connected and he has a safer king position. His immediate threat is RxR, when you have to retake with the king followed by Qg1+ and after you move Kd2 he will play Bb6 and the pressure around your king will become intense. You are paying ...

14 non-attacking bishops We may consider the white-square bishops and the black-square bishops separately. At most 7 bishops can be placed on white squares, namely, at most one bishop on each of the 7 white diagonals parallel to the h1-a8 diagonal. In fact, we can put bishops on the 7 white squares b1, d1, f1, h1, c8, e8, g8. The solution for black-square ...

One of the ways I teach kids how knights move is to put the queen and the knight on the same square. The knight can go to the nearest squares that the queen can't go to. It is this unique complimentary nature of the two pieces which means that they form such a potent combination. With queen plus any other piece this is missing and there is a duplication of ...

And the correct answer, as always, is: "it depends on the position" :-) OK, assume that you start with Bb1/Nc1. Lichess says +0.1. But this is the sum of... the N generally standing a bit ugly on c1/f1, from my positional feeling the B doing some concrete attacking (Stockfish unsubtly starts with c3) other random concrete aspects the question you ...

I believe Brian Towers and user58697 are correct, and the author wrote/meant pen instead of pin. The dictionary tells it's a small enclosure for animals, or an abbreviation for penitentiary, which seems more appropriate. Still, it's the first time I encounter this word in a chess setting, so it's not common and the confusion is understandable. While @...

Brian Towers' answer is excellent. I'll just add this: if you play Rxe8, you are effectively trading your e1-rook for your opponent's a8-rook. A glance at the position should show that your e1-rook is a lot more valuable than your opponent's a8-rook. It is currently already developed and participating in the game, while the a8-rook (like your a1-rook) is ...

John Watson's "Secrets of Modern Chess Strategy" contains a section titled "Folklore or Reality? Queens and Knights" John lists some folks that say Queen and Knight are better Capablanca Shirov Silman And refers to Steve Meyer's book "Bishop vs Knights" which also says the Queen + Knight is better. I am currently playing through "Karpov move by move" ...

For knights, the maximum is 32. Since knights can only attack the color opposite of the square they’re on, placing one on 32 squares of the same color is therefore optimal. [FEN "N1N1N1N1/1N1N1N1N/N1N1N1N1/1N1N1N1N/N1N1N1N1/1N1N1N1N/N1N1N1N1/1N1N1N1N w - - 0 1"] As for bishops, 14 is the highest possible. [FEN "B7/B6B/B6B/B6B/B6B/B6B/B6B/B7 w ...

Does “juicer” mean bishop? This YouTube video of Hikaru playing the Beth Harmon bot gives some clues. First, at 3:06 he says "I think I can just throw in a juicer check" and indicates a bishop check with arrows on the board. This suggests that juicer does mean bishop for him. However at 3:33 he says "I don't understand. I'm just up a juicer, ...

If given the choice should I opt for an endgame with a single Bishop or a single Knight? In order to properly answer this question I must point out differences between bishop and knight: Bishop is a faster piece and has a longer range of fire, but can cover only half of the board. Knight on the other hand, is a slow and clumsy piece but covers squares of ...

You need to understand that the point system is only a rough guideline meant to assist you in evaluating positions or in deciding on potential exchanges. Many factors, particularly the pawn structure, influences how valuable pieces are. Rooks tend to be better in open positions with fewer pieces/pawns on the board, bishops can get hindered in closed ...

The line usually quoted is 4.Bd3 Bxd3 5.Qxd3 Qa5+ 6. Bd2 Qa6! If White now exchanges Queens or allows the Queens to be exchanged he already has a poor endgame structure with a bad dark-square Bishop. Otherwise he will have difficulty Castling. Certainly White is not lost, but he has given away his first-move advantage. [FEN ""] 1. e4 c6 2. d4 d5 3. e5 Bf5 ...

I wouldn't say it was a "sacrifice", it was more like an exchange of bishops. My lichess engine was actually giving me ...Bd6 as the first move. I don't understand why it wants me to move my bishop to b4 in the first place Me neither. I doubt anyone here will have an idea. Stockfish doesn't tell us why. If I have to make a guess, I would say the ...

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

Are you familiar with the variant known as Crazyhouse? Basically, if you capture an opponent's piece, you can spend a later turn to place it anywhere you like on the board, as your own piece. This creates a situation where same-coloured bishops are possible, should you so choose. The ability to create bishop 'batteries' can be quite good, presuming that you ...

Tactics. Trading dark-squared bishops is useful in the long run, but a4-Ba3 is a bit too slow to exchange the Bf8 that hasn't moved yet; Also you weakened the dark square b4 in the process. Black can take advantage of the misplaced Ra3 to attack the weak pawn on d4. After 12...Bxa3 13.Rxa3 Qe7! {eyeing both a3 and h4}, any rook retreat or protection would ...

First, the good: You are probably winning this throughout the game, and thus, improving your position gradually was the perfect plan. It also was one of the best examples of Shereshevsky's "Do Not Hurry" principle that I have ever seen. Black could do nothing, so gradually improving, and eventually converting, was perfect since you had all the time in the ...

With new analysis from user AlwaysLearningNewStuff, we can conclude this is a win for white, The first critical position appears after 1.Be2 Kb7. [FEN "2k5/5b2/p7/P1p2p1p/P4P1P/2K2B2/8/8 w - - 0 1"] 1.Be2 Kb7 Black defends everything at the moment, but the only moves that keep the position are Kb7-a7-b7. A simple triangle maneuver ...

Something which might help here is Chess Query Language. Just like SQL does for relational databases, CQL can search in a database of chess games for positions/games which match certain criteria. I must say I have never used it myself, but it seems to be capable of amazing things, far more complex than what you're looking for. Here is an old article showing ...

A member of my club, rated about 1900 FIDE, had this in a championship blitz game about 2 years ago with 30 seconds left on the clock. He delivered mate with time to spare. IMs have failed. Go figure. If you study and learn then you should be able to deliver mate. If you don't study then you won't. Playing strength doesn't have that much to do with it.

But I have never seen 4. Bd3 played in titled games. The reason could be that Black gets a superior version of the French Defense. In the French, Black blocks the natural diagonal of the c8-bishop and then struggles to solve this issue. They lose a lot of tempi to exchange the bad c8-bishop via b6, and Ba6. Here Black immediately trades the light-squared ...

Once white has put pawns on the central white squares of d3, c4 and e4 his white squared bishop becomes very bad, because its mobility is drastically reduced, and his dark squared bishop becomes essential for protecting the dark squares that have become weak thanks to the pawn moves. That means that 7.Bd2 is a blunder because it allows black to exchange the ...

1. Bishop -vs- Knight The pawn structure decides. If the bishop side has pawns on opposite colors to the bishop => the opponent has pawns on the same color as bishop => bishop can attack the enemy pawn base => bishop is better. Still, the bishop side should not have too many weak pawns, so that the king can do the protection job properly. The knight is ...

Have a look at the wikipedia article on relative chess piece values, it provides an extensive discussion on the matter. To see how you can compare two given pieces, let's consider your bishop vs rook question at a basic level: A rook's movement is not restricted to a color, unlike the bishop's. This makes half of the board squares inaccessible to a bishop. ...
