To get out of check, the king needs to move to a square that isn't attacked by any opposing pieces, or you need to capture/block attacking pieces such that the king is no longer under attack on its current square. Since the queen is attacking the king and both of the unblocked squares it can move to, white needs to capture the queen to get out of check here. ...

Since you are a beginner in chess first you need to understand the term pin in chess. In chess, a pin is a situation brought on by an attacking piece in which a defending piece cannot move without exposing a more valuable defending piece on its other side to capture by the attacking piece. Now, coming to your answer: Rook cannot capture the queen at f7 as ...

Rook at d2 is pinned by the bishop at g5 and hence the rook can not capture the black queen at c2 checkmating the white king at c1.

Did black just play f5 before? Then the right move is exf6 en passant, Bxf6 Rxf6 Rxf6 Qe5+ and win the piece. [FEN "2b2r1r/2k1qpb1/2p1p2p/1p1pP3/pP1P1RB1/P1N5/2P1Q1PP/5RK1 b - - 1 1"] [StartFlipped "0"] [StartPly "3"] 1... f5 2. exf6 Bxf6 3. Rxf6 Rxf6 4. Qe5+

There are two checkmates per orientation: [title "Mate in one"] [FEN "3b4/R3P3/2kPR1n1/P1p1n3/4K1p1/2Nr4/5p2/1b6 w KQkq - 0 1"] 1. exd8=N# and [title "Mate in one"] [FEN "3b4/R3P3/2kPR1n1/P1p1n3/4K1p1/2Nr4/5p2/1b6 b KQkq - 0 1"] 1... Rxc3# and [title "Mate in one"] [FEN "6b1/...


22

After Qa4 Black can reply ...Kf8 if you capture there's ...Qd7 (pinning your knight and regaining it later) A continuation would be 1.Qa4 Kf8 2.Nxc6 Qd7 3.Bb5 a6 4.Nxe7 axb5

I'll have a go at saying the queen is the only piece that cannot reveal a discovered check.

Frankly, you overlooked a major detail...Nf6+ in reply is mate. It is important to notice your "opponent's" moves too. [FEN "r2qk2r/pp1nnp1N/4p1pQ/3pP3/4b1PP/P1B5/1PP1B3/R3KR2 b Qq - 0 1"] 1... Nf8 $4 (1... Ng8! 2. Qg7 (2. Nf6+ Qxf6 $1) 2... Qxh4+ 3. Kd2 Qxh7) 2. Nf6#

This is a familiar tactic I often get to use myself in another opening line. If black plays 1... Rf8, then comes 2. Bc7! Qe8 3. Nd6 Bxd6 4. Bxd6 and black loses the exchange anyway. [Title "White to move"] [FEN "r1bqr1k1/pp1nbpp1/4pn1p/2pp4/2PP1B2/P1NBPN2/1P3PPP/R2Q1RK1 w - - 0 1"] 1. Nb5 Rf8 2. Bc7! Qe8 3. Nd6 Bxd6 4. Bxd6 Chess is about patterns. Since ...

After 1...Rxd5 2.cxd5, both queens are attacked. They either both get captured, or (if black moves his to safety) neither is. So black lost the exchange. After 1...Qxd5 2.cxd5 Nxe2, white has lost a knight. Cxd5 seems the better capture to me on general grounds (repairs white structure a bit, makes pawn c5 weaker) but that's far less important than the full ...

As a chess composer, seeing most problems being called puzzles is rather frustrating. A while ago, I personally revamped the problem and puzzles tags. The problem tag says: Chess problems consist of a board position and a task. Most ask for a line of play that mates black in a set amount of moves, or a combination that results in a winning position. Many ...

If black plays QxR then white plays Qc3+ with mate to follow. Black's Qg7 stops the mate. With the black queen on b2 white cannot play Qc3. The Re2 move is to divert the black queen [FEN "5r1k/1pQ4p/3nB1p1/3P4/5p2/1P5P/rq5P/4R1RK w - - 0 1"] 1. Re2 Qxe2 2. Qc3+ Qe5 3. Qxe5+ Rf6 4. Qxf6#


15

I'm an FM, and my calculation process would be as follows: See that after 2.Rxg4 Qxh6 2.Rg8 Bf8, I'm clearly winning and White has no follow up. Look at White's king moves to get out of check. Immediately Kd2 and Kd3 can be discarded since they just let me play ...Rd8+ for free. Also, Kf1/Kf2 lead to the same thing after I play 2...Qf3+. So I'd just look ...


14

The problem is that 5. Qxh5 isn't check, so Black has time for some back rank tricks (instead of capturing the rook on f6): [FEN "r1r4k/1p5R/3b4/4q3/B3P1Q1/1n1P3P/6P1/5R1K b - - 0 1"] 1... Kxh7 2. Rf7+ Kh6 3. Qh4+ Qh5 4. Rf6+ (4. Rh7+ Kxh7 5. Qxh5+) Kg7 5. Qxh5 Rc1+ 6. Qd1 Rxd1+ 7. Rf1 Rxf1#


13

Black is going to lose the bishop regardless. White is attacking the queen in such a way that it will have to move (or be captured), and there are no available safe squares from which it can continue to protect black's bishop. After the queen retreats, white will be free to capture the bishop with his bishop. By playing Bh3 first, black can at least generate ...

At first glance, before concrete calculation: 1 Kh1 looks reasonably safe, the king is out of harms way for good. 1 Rf2 self-pins the rook and disjoints White's whole army with no obvious upside. Why play it over 1 Kh1? Looking a bit further, Black's queen is almost out of escape squares. However, the Rf1 is the only piece that can reasonably seal the trap ...

When a chess engine shows an evaluation of a position, there are typically 3 possible values, all of which are based on the engine's attempt to simulate perfect play for both sides: (1) If the engine sees a forced checkmate [meaning, when one side plays perfectly, no matter what the other side does, the winning side can checkmate], it will indicate how many ...

Does it make most sense to just start playing with setting up all the pieces, or are there smaller "games" that one can/should start with? It doesn't really matter the age of the person learning to play, there is no point in starting with a full set. There is just far too much to take in and make sense of. The first thing to do is to teach them how to win!...

There is a similar ancient question, but this isn't a duplicate since White may move anywhere. For an upper bound, I can prove a guaranteed win for White in 5 moves. Indeed, it is reminiscent of Scholar's Mate. [FEN ""] 1. e3 null 2. Bc4 null 3. Qf3 null 4. Nh3 null 5. Ng5 With Black to move, as White has now used up their five given moves, ...

According to the FIDE Laws of Chess: 1.4 The objective of each player is to place the opponent’s king ‘under attack’ in such a way that the opponent has no legal move. 1.4.1 The player who achieves this goal is said to have ‘checkmated’ the opponent’s king and to have won the game That means that if white has a knight which is 2 normal knight moves away ...

Rating method. On chess.com, my puzzle rating is 700 points higher than my game rating, but my chesstempo puzzle rating is only about 100 points higher than my chess.com game rating. In other words, puzzle rating on chess.com is not comparable with your game rating. I'd suggest just keep doing 10 (or more) puzzles a day and ignore whatever the gap.

White is a piece up and has a completely winning position. Black could try to create some counterplay profitting from the fact that White's pieces are a bit uncoordinated right now. But realistically, any decently skilled player should be able to convert this position into a win for White. Finally, note that there's no threshold for which positions can be ...

[FEN "2k1r3/pp6/n5q1/1N3p2/8/3B4/5PPP/5RK1 w - - 0 1"] 1. Bxf5 Qxf5 2. Nd6 and a cute family fork wins the queen. White is up a pawn.

The original goal of chess was to capture the opponent’s king. The idea of “checkmate” follows this: you may as well call the game won/lost once capture next turn is inevitable. So you’re checkmated if whatever you do, your king would get captured next turn — i.e. if every move you can make would leave your king still in check. In your example: There are ...

A Queen cannot be captured when static by an attacking King. A Queen cannot capture a piece more valuable than itself. A Queen cannot move to create a discovered check. A Queen cannot sacrifice itself for a higher valued piece. A Queen cannot initiate a double check.

I tend to disagree with the other answers that suggest starting with just a few pieces. Kids absorb so much, so quickly. When my daughter was 4, she used to just watch me so she got some familiarity with the shapes of the pieces, but there was no teaching at this time. When she was 5, I taught her the names of the pieces, and then how they all moved. I did ...

There is a lot more to this, and this is really not a great tactics problem as much as it is a continuing the attack problem. The difference is that with a tactic problem, you can see the result all the way to the end. Other positions, you have just a feel for it, and you know that you are probably winning, but you have to play what you can calculate, you ...

You haven't understood the puzzle. The puzzle asks you to find the best move for white after Bxg4 by black. It does not ask you to find the best move for black after Rh1 by white. Having found Rh1 for white the moves that follow are illustrative only. They do not show all the possible black replies and there is no suggestion that the line chosen for black is ...

One way to fool some computers is to give them a fortress and then offer material to trick them into opening the portcullis. For example: [Title "White to draw"] [FEN "8/8/pr1k4/Pp2rp1p/1Pp1pPpP/2PpP1P1/3P4/3K4 w - - 0 0"] 1. fxe5+?? (1. Ke1) (1. Kc1) 1... Kxe5 2. axb6 Kd6 0-1 Many computers won't resist the temptation to win RR for ...
