1. Checkmate doesn't wait for the endgame

Chapter Four covered the mechanical checkmates you deliver once almost everything is off the board. But most checkmates don't happen in that bare endgame — they happen in the middlegame, with plenty of pieces still around. This chapter is a catalogue of recognizable mating patterns you should be scanning for constantly, whether you have one attacking piece or several working together.

2. Solo-act checkmates

A "solo-act" checkmate is delivered by a single piece, with no other piece needed to defend it or cover an escape square. These only happen because the defending side has made a serious mistake, but that mistake is common — so keep watching for it, both to punish your opponent and to avoid it yourself.

Back-Rank Mate is the most common solo act. A castled king, boxed in by its own pawns, can be mated by a single rook or queen sliding onto the back rank. White is down significant material in the position below — see if you can find the mate in one before you check the solution.

Board 1 — Re8# is Back-Rank Mate: White is down 7 points of material, but Black's own pawns block every escape from the 8th rank, and nothing can block or capture the rook.
Watch out

Always leave your own castled king a luft — an escape square, usually made by pushing one pawn in front of it one square — so you can never be Back-Rank Mated yourself.

Fool's Mate is a diagonal solo-act mate delivered by a queen, famous for being the fastest possible checkmate. It needs two genuinely bad opening moves from White.

Board 2 — Fool's Mate: 1.f3 e5 2.g4?? Qh4# — the queen attacks the White king diagonally along a hole in the pawn shield, and nothing can block, capture, or run.

The queen is even more dangerous than a rook on the back rank, because it also covers diagonals — so an escape square isn't always enough.

Board 3 — Checkmate, even though g7 looks like a luft square: a rook here would let the king run to g7, but the queen covers that square diagonally too.

A bishop can deliver the same kind of diagonal solo mate whenever the enemy king is completely crowded in by its own pieces along that diagonal. This is rare — it takes real cooperation from the defender — but it does happen in actual games.

Board 4 — Checkmate: Black's king is boxed into the corner by its own pieces, and none of them can capture or block the White bishop delivering check along the long diagonal.

Rarest and most fun of all is the Smothered Mate: an L-shaped mate from a knight, delivered when the enemy king has been walled in entirely by its own pieces.

Board 5 — Checkmate: Black's own rook, pawns and king have left no breathing room in the corner, so the lone White knight on f7 delivers mate on its own.
Note

Fun fact: Rozman admits that his own puzzle stats aren't perfect either — by his own account, according to Chess.com's puzzle stats, he only solves Smothered Mate puzzles correctly 76 percent of the time. Even a titled player misses the pattern sometimes, which is exactly why it's worth drilling: the shape is simple, but spotting it under time pressure is its own skill.

All four solo-act patterns share one theme worth restating: they don't happen because your attacking piece is special, they happen because the defending king was left abandoned, badly guarded, or boxed in by its own side. Watching for that same weakness in your opponent's position — and refusing to create it in your own — is the actual skill being taught here.

3. Two-piece checkmates

Most checkmates you'll actually deliver need two pieces working together, because a well-defended king can't be mated by one attacker alone. The most common pairing puts a queen in front, protected by a lesser piece behind it — an arrangement called a battery, where two pieces line up on the same rank, file, or diagonal so the front piece can attack while the back piece guards the square it lands on. A queen and bishop, a queen and rook, or even two queens (after a promotion) can all form a battery. See if you can spot the mate in one below before checking the solution.

Board 6 — Both sides made luft (h3 and h6) so back-rank mate is off the table, but White's queen-and-bishop battery is aimed straight at g7. Qxg7# — only the king guarded that pawn, and the king can't recapture because the bishop defends the queen.

The two attackers don't need to start on the same line, either — they just need to end up threatening the same square from different angles. You've actually already seen this idea: back in Chapter 2, the queen-and-bishop combination behind the Scholar's Mate wasn't a formal battery either — the queen and bishop simply converged on f7 from different directions, and the king couldn't recapture because the bishop defended the queen. See if you can spot this game's mate in one before checking the solution.

Board 7 — The queen and bishop don't start on the same diagonal here, but they both bear on b7. Qxb7#: the bishop on g2 stops the king from recapturing, and there's no safe square to run to. (Note Black's own queen and rook form a battery on the h-file — if it had been Black to move, ...Qxh2 would have mated first.)

A knight can also stand in for the bishop, defending the queen's mating square from a completely different kind of angle, since nothing else attacks the way a knight does. Take the same battery position with the bishop removed: where could White drop a knight in to combine with the queen on c3 for mate? There are two answers.

Board 8 — Qxg7# is mate with a knight on f5: the king can't take the queen because the knight guards g7.
Board 9 — A knight on h5 works just as well — same idea, a different guard square for the same king.

Here's a second version of that same puzzle to test the pattern: take the earlier queen-and-bishop position where White won the game by capturing on the queenside, remove the bishop, and ask the same question — where does a knight belong so it can guard the queen from there instead? Again there are two answers. Try to spot the finishing move in the first position below before checking the solution.

Board 10 — With a knight parked on a5, 1.Qxb7# works: the king can't recapture because the knight watches b7.
Board 11 — A knight on c5 mates the same way — a different guard square, same checkmate.

Notice the pieces don't even have to go queen-first. Sometimes the lesser piece delivers the actual check while the queen sits behind it as the defender — the roles simply swap, and the mating idea is identical either way.

Rooks and bishops combine well too, and not always by directly defending each other — sometimes the bishop's job is just to cover the king's own escape square (its luft) while the rook delivers the check on the back rank.

Board 12 — Checkmate: the bishop on h6 defends the rook on f8, which checks along the back rank. Black's own king and pawns block every other square.
Board 13 — Another common rook-and-bishop pattern: the bishop on d3 isn't attacking the king at all — it's covering the king's own luft square, so the rook's back-rank check on e8 can't be answered.

Even a bishop and knight, without any major piece at all, can combine: the knight delivers the check while the bishop seals off the squares around the king.

Board 14 — Checkmate: the knight on h6 checks the king on g8, while the bishop on f6 covers both g7 and h8. The king's own rook and pawn block the rest.

4. Removing the defender and forced checkmate

Sometimes the piece stopping your mate isn't the king's escape squares — it's a single defender guarding the key square. Removing the defender means capturing or deflecting that piece, even at a material cost, so the mating move becomes possible. Giving up a rook for a knight is normally a poor trade, but if it clears the way to checkmate, the point count stops mattering. Try to find the idea below before you check the solution.

Board 15 — Removing the defender: White's queen and bishop are already lined up on g7, but the knight on f5 guards it. A rook (worth 5) for a knight (worth 3) is normally a bad trade, but 1.Rxf5 removes the defender: if Black recaptures with 1...exf5, 2.Qxg7# follows — protected by the bishop. Switch to Declining: 1...f6 to see Black's only way to dodge mate, which simply leaves White a knight up instead.

This is also a clean example of a forced checkmate: a position where the correct moves make checkmate unavoidable, however the defender responds. Forced mates in one move are the easiest to spot — any of the boards above. From there, train yourself to see forced mates in two moves, then three, by asking what you'd play if you had several moves in a row, then working out how to make each of those moves forcing (usually a check, or an attack on a piece your opponent must deal with immediately). Can you solve the forced mate in two below before checking the solution?

Board 16 — A forced mate in two: the bishop on c3 already eyes h8, but the queen can't get there in one move. 1.Qh4+ forces the only legal reply, ...Kg8, and now 2.Qh8# — protected by the bishop — can't be met.

Puzzle collections, in books or online, are the best way to build this skill quickly — start with mates in one, then work up to two- and three-move forced sequences.

5. Summary

Solo-act checkmates — Back-Rank, Fool's Mate, diagonal bishop mates, and the Smothered Mate — all rely on the defending king being abandoned, poorly guarded, or boxed in by its own pieces; they need no help from a second attacker, but they do need a defensive mistake. Two-piece checkmates are far more common in real games: a queen paired with a bishop, rook, or knight in a battery or from converging angles, or even a rook-and-bishop or bishop-and-knight pair with no queen at all. When the mating square is defended, look for a way to remove the defender, even at a material cost. All of this feeds into forced checkmate: sequences where, if you find the correct moves — usually checks or immediate threats — your opponent cannot escape, no matter what they try.

Check yourself

What makes a checkmate a "solo act," and name two examples.

A single piece delivers mate with no second piece needed to defend it or cover an escape square, because the defending king is already trapped by its own pawns or pieces. Examples: Back-Rank Mate, Fool's Mate, a diagonal bishop mate, and the Smothered Mate.

How can you prevent your own king from ever suffering a Back-Rank Mate?

Make a luft — push a pawn in front of your castled king one square — so the king always has an escape square off the back rank.

What is a "battery," and which pieces commonly form one?

Two pieces lined up on the same rank, file, or diagonal so the front piece attacks while the back piece defends the square it lands on. Common batteries: queen and bishop, queen and rook, or two queens after a promotion.

In Board 6's Qxg7# battery, why can't the Black king recapture the queen?

Because the White bishop on b2 sits on the same diagonal behind the queen and defends g7 — if the king captured the queen, the bishop would recapture the king (which is exactly what "defended" means: the square is covered by a second attacker).

What is "removing the defender," and why can it be worth sacrificing material?

It's capturing or deflecting the one piece that's guarding a key square, even at a cost (like trading a rook for a knight), because clearing that defender makes the mating move possible. Once checkmate follows, the point count no longer matters.

What is a "forced checkmate," and how should you train to spot longer ones?

A position where, if you find the correct moves, checkmate cannot be avoided no matter how the opponent responds. To improve, practice mates in one first, then imagine several moves ahead and look for ways to make each move forcing — usually a check or an immediate threat — then solve puzzles to build the pattern recognition.

Why does a knight make an especially effective partner for a queen in a two-piece mate?

Nothing else moves the way a knight does, so a piece it defends can't be captured by anything that would also be attacking the knight in return — the knight's protection is essentially invisible to normal lines of attack.

In Board 13, what two separate jobs are the rook and bishop doing?

The rook delivers the actual checkmate along the open back rank. The bishop isn't attacking the king directly at all — it's covering the king's own luft square, the one pawn move Black made to try to avoid exactly this mate.

Boards 10 and 11 both mate with Qxb7 supported by a knight, on a5 or c5. What do those two squares have in common?

Both are the only two squares from which a knight defends b7 without being captured itself or blocking the queen's path there — the same "where would you drop a piece" logic as the earlier f5/h5 puzzle on g7. Recognizing that a square needs defending, then scanning for every piece that can guard it unnoticed, is the actual skill being tested.

Does the queen always have to be the piece that delivers the final check in a two-piece mate?

No. The roles can swap — sometimes a knight, bishop, or rook delivers the check while the queen sits behind it as the defender. What matters is that one piece attacks the king and a second piece guards the square the first piece lands on, not which piece plays which role.

According to the chapter, does being a titled player mean you never miss a Smothered Mate pattern?

No — by Rozman's own admission, he only solves Smothered Mate puzzles correctly a little over three-quarters of the time. Even strong players miss it under time pressure, which is exactly why it's worth deliberately drilling rather than assuming you'll just spot it in a real game.
