The Deflection That Wins the Queen: A Study in Interference

Greetings, tacticians. The 2025 Superbet Classic in Bucharest has been serving up razor-sharp middlegames, but today I want to drag you into the endgame — where, contrary to popular belief, the tactics don't stop. They just get more ruthless.

Consider the position below. White to move, and material is roughly balanced (queen and rook each), but look closer. Black's king is stranded on g5, cut off, exposed, and just begging to be mated.

FEN: 1Q5R/1p4r1/p1p5/3b2kP/8/P4qP1/1P3P1K/8 w - - 1 1

Reading the Position

Before we calculate, let's take inventory like a proper club player should:

• Black's king sits on g5 — a wandering monarch with almost no shelter.
• White has a queen on b8 and a rook on h8. The rook already eyes the h-file, and the pawn on h5 controls key squares.
• Black's queen on f3 and bishop on d5 look active, but they're doing defensive duty. If they get pulled off their diagonals, the king is naked.
• The g3-pawn and White king on h2 keep Black's queen from delivering any nasty checks of its own.

The whole story here is the g7-square. If White could ever land a rook there with check, the king on g5 would be in a mating web. The problem? Black's rook sits on g7, guarding it. So how do we remove that defender?

The Solution

The winning idea is a gorgeous three-move combination:

1. 1. Qe5+! — The queen leaps into the center with check. This is the key move. It's not just a check; it's a deflection with interference. The queen slots onto e5, blocking the a1-h8 diagonal and forcing Black's hand.
2. 1... g4 — Forced. The king has no squares (h5 is covered by the pawn, f-squares run into checks and the queen), so Black interposes... except there's nothing to interpose. The pawn push g4 is the only try to give the king luft on g5, but it doesn't help.
3. 2. Qxg7+! — And there it is. White's queen captures the rook with check, and now the deflection theme completes: Black's g7-rook, the sole defender of the g7-square, is gone. The king is caught in a mating net, White is up a full rook, and the game is decided.

Why does Qe5+ work so beautifully? Because it does three jobs at once: it checks the king, it lands on a square Black cannot capture (the d5-bishop and f3-queen can't reach e5 usefully), and it sets up the follow-up capture on g7. The move g4 doesn't create a defense — it just marks time before the collapse. This is a textbook case of what I call "the check that removes the guard."

Drilling the Pattern: Deflection of the Defender

The pattern here — force the king to a square, then capture its last defender with check — shows up constantly. Let me give you two supporting shots to burn it into memory.

Example 1: The Overworked Rook

Imagine a simplified motif: White queen on b8, rook on h8, Black king on g8 with a rook on g7. The move Qxg7+! (when g7 is defended only by the king, or the defender is pinned) crashes through. The lesson: a piece that guards one critical square is a piece begging to be deflected.

Example 2: The Zwischenzug Check

Recall Reti–Bogoljubov, New York 1924, where after 22. Bf7+! the king was yanked forward before the final 23. Qxg6#-style ideas landed. The theme is identical: use a check to reposition the enemy king or deflect a defender, then deliver the blow. Order of operations is everything.

The Takeaway

When you see an exposed enemy king in the endgame, don't reach for the obvious capture first. Ask instead: What single defender is holding this together, and can I remove it with tempo? In our featured position, 1. Qe5+ g4 2. Qxg7+! works precisely because the check on e5 forces the position and the capture on g7 eliminates the only guard of the mating square.

Endgames aren't the place where tactics die — they're the place where a single alert move wins the whole point. Set up this position, cover the answer, and find Qe5+ for yourself. Then go hunt for overworked defenders in your own games.
