Quick answer
Queen Endgame Checking Technique is an endgame technique: queen against rook coordination. Work from the first evidence position for Queen Endgame Checking Technique, and begin by testing Kh6.
Begin from Kh6 in 7k/6r1/8/7K/Q7/8/8/8 w - - 4 3. Count the material, king routes, promotion squares and reserve tempi before applying a theoretical rule. The evidence answer is: Queen Endgame Checking Technique: use checks and king safety to separate the rook from the defending king. Candidate line: Kh6.
In the Queen Endgame Checking Technique example, notice: side White; pieces Black king h8, Black rook g7, White king h5, White queen a4; legal first moves Kh6, Kh4, Qa5, Qa6, Qa7, Qa8+, Qb5, Qc6. Anchor your reading to the FEN above; the inventory is illustrative, not a portable law of chess.
Material and result question
The first evidence board tests queen against rook coordination; the second board tests queen against rook coordination. Use direct FEN setup to reconstruct A and direct FEN setup to reconstruct B when the evidence includes move text. Shared language is catalogued on the Chess Wiki and the Endgames hub. Then compare Material Values with Queen Endgame Perpetual Check, Rook Versus Minor Piece, Rook And Bishop Versus Rook around the pawn's promotion square.
The two inventories make the distinction concrete. A contains side White; pieces Black king h8, Black rook g7, White king h5, White queen a4; legal first moves Kh6, Kh4, Qa5, Qa6, Qa7, Qa8+, Qb5, Qc6; B contains side Black; pieces Black rook g7, Black king h7, White king f6, White queen a1; legal first moves Rg8, Rg6+, Rg5, Rg4, Rg3, Rg2, Rg1, Rf7+. Compare the side to move before comparing the labels in the context of the defender's fortress setup.
Topic dossier for this page and board pair r1:7k | r2:6r1 | r3:8 | r4:7K | r5:Q7 | r6:8 | r7:8 | r8:8 / r1:8 | r2:6rk | r3:5K2 | r4:8 | r5:8 | r6:8 | r7:8 | r8:Q7: start with the pawn's promotion square; then test the defender's fortress setup; keep an outside passer used as a decoy separate from the defender's only active counterplay; use the active rook before the pawn push as the transfer check; and reserve the conversion move order for the exception.
Conversion or defense plan
On the first board, calculate Kh6 after Kh6 and write down the opponent's best reply around the pawn's promotion square. On the second board, calculate Rg8 after Rg8 and check the defender's fortress setup. Separate the practical conversion question from the result question; side to move and one checking distance can change the conclusion. In this case the useful condition is the conversion move order.
Key claim: Queen Endgame Checking Technique is illustrated here by queen against rook coordination; the first concrete test is Kh6. The board anchor is 7k/6r1/8/7K/Q7/8/8/8; the example is intentionally narrower than the topic label and should not be generalised without checking the surrounding position..
Practical boundary: To answer “What exact king, pawn, and move-order conditions decide queen endgame checking technique, and how should each side play them?”, compare the recorded setup with Rg8 and the opponent's reply. The decision is useful only when the stated condition survives that concrete test on board 8/6rk/5K2/8/8/8/8/Q7. The evidence records No tablebase outcome is asserted by this generated record; verify the exact FEN before publication and the second board signature r1:8 | r2:6rk | r3:5K2 | r4:8 | r5:8 | r6:8 | r7:8 | r8:Q7. The false-positive test is whether an outside passer used as a decoy appears without the defender's only active counterplay, so the conclusion is useful only when the stated condition survives that concrete test.

example-3: queen against rook coordination
Show answer
Queen Endgame Checking Technique: use checks and king safety to separate the rook from the defending king. Candidate line: Ke6.
Why this position is here: Queen Endgame Checking Technique is represented by queen against rook coordination. This is a direct FEN setup with board anchor 8/r6k/8/5K2/8/8/8/2Q5; no opening history is inferred from the diagram.

Reading the line
Read the first example (id example-1) as a complete record: continuation Kh6, source tablebase. This is a direct FEN setup with board anchor 7k/6r1/8/7K/Q7/8/8/8; no opening history is inferred from the diagram. If A does not expose queen against rook coordination, correct the evidence before relying on the prose.
Read the second example (id example-2) separately: continuation Rg8, source tablebase. Its feature is queen against rook coordination; inventory side Black; pieces Black rook g7, Black king h7, White king f6, White queen a1; legal first moves Rg8, Rg6+, Rg5, Rg4, Rg3, Rg2, Rg1, Rf7+. Compare what changes between Kh6 and Rg8.
Boundary cases
The main mistake to avoid with Queen Endgame Checking Technique is applying a remembered endgame rule while ignoring side to move, king placement or an unverified result. In A, the missing condition must be located in r1:7k | r2:6r1 | r3:8 | r4:7K | r5:Q7 | r6:8 | r7:8 | r8:8 after Kh6; in B, test it against r1:8 | r2:6rk | r3:5K2 | r4:8 | r5:8 | r6:8 | r7:8 | r8:Q7 after Rg8.
For Queen Endgame Checking Technique, the first board's evidence boundary (after Kh6) is No tablebase outcome is asserted by this generated record; verify the exact FEN before publication. The second board's evidence boundary for Queen Endgame Checking Technique is No tablebase outcome is asserted by this generated record; verify the exact FEN before publication. If a trusted source or careful calculation changes the conclusion around the active rook before the pawn push, update both the evidence record and this article.
Practice from a real game
play the position for both sides, record the critical tempo, and verify the exact FEN against the cited tablebase before publication. Start with A's side to move and r1:7k | r2:6r1 | r3:8 | r4:7K | r5:Q7 | r6:8 | r7:8 | r8:8; record two candidates, the reply to Kh6 and the correction. Repeat with B's side to move and r1:8 | r2:6rk | r3:5K2 | r4:8 | r5:8 | r6:8 | r7:8 | r8:Q7; the changed board tests transfer rather than diagram memory.
After the drill, compare your notes with Queen Endgame Perpetual Check, Rook Versus Minor Piece, Rook And Bishop Versus Rook through the defender's only active counterplay. Keep A's rejected alternative beside B's chosen line Rg8; this shows whether the conclusion survived a new board signature.
