Two Chess Puzzles You Solve With Your Hands

Say chess puzzle to someone who plays and they picture a diagram. White to move, mate in three. You study the position, you spot the sacrifice, you are done in four minutes.

These are not that.

Queen's Attack and Swapping Castles are physical objects that sit on a desk. The pieces move by ordinary chess rules, and that is where the resemblance stops. There is no opponent, no checkmate, no clock, and - the part that undoes most chess players - nothing can be captured. Every piece that is in your way stays in your way until you move it somewhere else.

Both are designs by Sherzod Khaydarbekov, and every design of his we stock is built the same way: a board cut to fit the problem, real chess moves, and a position no actual game would ever hand you.

Both live in chess puzzles, and there is more on how he designs them in his designer profile.

Not the Kind of Chess Puzzle You Are Expecting

A classic chess puzzle is a position lifted out of a game. The skill it tests is seeing - you are looking for a tactic that already exists on the board.

These two are mechanical puzzles that borrow chess movement as their rule set. The skill they test is traffic management. The board is deliberately overcrowded, captures are off the table, and every piece you move to solve one problem creates a new blockage somewhere else. The nearest relative is not a chess problem at all - it is a sliding block puzzle, the kind where you shuffle tiles around a single empty space.

That does not make chess knowledge useless here. It makes a different part of it useful. The habit a player has drilled hardest - scan for captures, count threats - has nothing to bite on. But the feel for how pieces cover ground, how much space a knight eats up, which squares a bishop can never reach, is precisely what these lean on. Chess players tend to do well at them. They just get there through board sense rather than calculation.

Queen's Attack: Promote First, Hunt Second

The tray holds a white army - four knights, four rooks, four bishops and three pawns - and two black pawns. Your job is to take the black pawns with a white pawn.

There is a clue in the name, and it is worth spotting before you start: the queen is missing. She is not somewhere on the board waiting to be freed. She does not exist yet.

So the puzzle is really two puzzles stacked. First you have to walk a single pawn the length of a board packed with your own pieces, none of which you can remove, to reach the far rank and promote. That stage is slow, and it is where most attempts die. Then you have a queen - and a queen changes everything, because she covers ground that a pawn spent twenty moves crossing. The second half plays much faster than the first.

Greg's own description of solving it is that there are many different routes through, and it feels different every time. That is unusual and it is the reason it survives being solved more than once.

Swapping Castles: Eight Rooks, Not Enough Room

Four black rooks down one side. Four white rooks down the other. Swap them completely, using the handful of empty squares in the middle, and again without capturing anything.

Rooks are the cruellest piece to build this from. They move in straight lines for any distance, which sounds generous until you notice the consequence: every rook is simultaneously a vehicle and a wall. A rook that moves into the middle to make progress is now blocking the file or rank that the next rook needed. There is no piece here that gets out of the way politely.

If the name puzzles you, castle is the everyday name for the rook - the corner piece shaped like a tower. Nothing to do with castling, the king-and-rook move.

The Board Is Deliberately Too Small

Look at either tray and you will see the puzzle's real design decision, hiding as decoration.

The engraved titles - QUEEN'S ATTACK across one, SWAPPING CASTLES across the other - are not printed on the surface. They sit on raised panels that occupy squares. Those squares are gone. They are walls.

That is the whole trick of the format. On a full, open board neither of these problems is interesting - a pawn strolls up an empty file, rooks swap sides in a few moves. Every square the designer takes away turns a free move into a negotiation. The lettering is not branding that happens to sit on the board. It is the difficulty.

Do You Need to Be Good at Chess?

You need to know how the pieces move. That is the entire requirement.

No openings, no endgame theory, no evaluation, no notation. If you can remember that a bishop stays on its colour and a knight jumps in an L, you have everything the puzzle asks for.

A low floor is not the same as being wasted on a strong player, though - if anything it is the reverse. Someone who genuinely enjoys chess gets the most out of these, because they already read a board without having to think about it, and because they know exactly what it means when a pawn finally reaches the eighth rank. The requirement is small. The pleasure scales with how much you like the game.

The same is true of the rest of Khaydarbekov's designs. They assume you know how the pieces move and assume nothing beyond that. It is a narrow brief to design inside, and it is why they sit just as happily with a club player as with someone who only remembers the rules.

Frequently Asked Questions

Which Chess Puzzle Should You Get First?

If you want the one with a story arc, take Queen's Attack - the promotion moment is a genuine turn and the second half feels like a reward.

If you want the one that fits in a pocket and comes out on a train, take Swapping Castles. It is in the pocket puzzles collection for a reason.

Both sit alongside the rest of the range in the mechanical puzzles collection, and if you like the idea of a puzzle whose difficulty is pure geometry rather than borrowed from a game, the Three-Piece Block is the other end of that spectrum.
