Quick answer
Insufficient Material Draws is a rules question: a bare-king insufficient-material position. Work from the first evidence position for Insufficient Material Draws, and begin by testing Kb2.
Begin from Kb2 in 8/8/8/8/8/2K5/8/3k4 w - - 2 2. Read the side to move, legal conditions, history fields and procedural distinction before relying on a shortcut. The evidence answer is: Insufficient Material Draws: separate an automatic dead position from a draw claim that depends on history or procedure. Candidate line: Kb2.
In the Insufficient Material Draws example, notice: side White; pieces White king c3, Black king d1; legal first moves Kb4, Kc4, Kd4, Kd3, Kb2, Kb3. The listed material and candidate moves belong only to this FEN example and should not be generalised.
The exact condition
The first evidence board tests a bare-king insufficient-material position; the second board tests a bare-king insufficient-material position. Board A’s recorded route is direct FEN setup. Board B’s recorded route is direct FEN setup. Cross-check wording on the Chess Wiki and on the Rules hub. Then compare Piece Movement with The Fifty Move Rule, Dead Position Draws, Touch Move Rule around a claim versus an automatic draw.
The two inventories make the distinction concrete. A contains side White; pieces White king c3, Black king d1; legal first moves Kb4, Kc4, Kd4, Kd3, Kb2, Kb3; B contains side Black; pieces White king c4, Black king b2; legal first moves Ka3, Kc2, Kc1, Kb1, Ka1, Ka2. Compare the side to move before comparing the labels in the context of resignation versus a draw offer.
Topic dossier for this page and board pair r1:8 | r2:8 | r3:8 | r4:8 | r5:8 | r6:2K5 | r7:8 | r8:3k4 / r1:8 | r2:8 | r3:8 | r4:8 | r5:2K5 | r6:8 | r7:1k6 | r8:8: start with a claim versus an automatic draw; then test resignation versus a draw offer; keep the en-passant window separate from the arbiter's role in a claim; use the dead-position exception as the transfer check; and reserve the legal castling test for the exception.
Procedure and counterexample
On the first board, calculate Kb2 after Kb2 and write down the opponent's best reply around a claim versus an automatic draw. On the second board, calculate Ka3 after Ka3 and check resignation versus a draw offer. Separate what the board proves from what only the move record, clock or arbiter can establish. In this case the useful condition is the legal castling test.
Key claim: Insufficient Material Draws is illustrated here by a bare-king insufficient-material position; the first concrete test is Kb2. The board anchor is 8/8/8/8/8/2K5/8/3k4; the example is intentionally narrower than the topic label and should not be generalised without checking the surrounding position..
Practical boundary: To answer “When is insufficient material draws legal, what exceptions matter, and how can a player verify the rule at the board?”, compare the recorded setup with Ka3 and the opponent's reply. The decision is useful only when the stated condition survives that concrete test on board 8/8/8/8/2K5/8/1k6/8. The evidence records The position tests the stated rule or record field; verify the relevant source when a procedural decision matters and the second board signature r1:8 | r2:8 | r3:8 | r4:8 | r5:2K5 | r6:8 | r7:1k6 | r8:8. The false-positive test is whether the en-passant window appears without the arbiter's role in a claim, so the conclusion is useful only when the stated condition survives that concrete test.
Evidence positions
example-1: a bare-king insufficient-material position
Show answer
Insufficient Material Draws: separate an automatic dead position from a draw claim that depends on history or procedure. Candidate line: Kb2.
Why this position is here: Insufficient Material Draws is represented by a bare-king insufficient-material position. This is a direct FEN setup with board anchor 8/8/8/8/8/2K5/8/3k4; no opening history is inferred from the diagram.
FEN: 8/8/8/8/8/2K5/8/3k4 w - - 2 2
Question: What is the first concrete decision in this insufficient material draws position?
Answer cue: Insufficient Material Draws: separate an automatic dead position from a draw claim that depends on history or procedure. Candidate line: Kb2. The first candidate to test is Kb2. Replay Kb2 on board anchor 8/8/8/8/8/2K5/8/3k4 and write down what changes after it.
Evidence boundary: The position tests the stated rule or record field; verify the relevant source when a procedural decision matters.
example-2: a bare-king insufficient-material position
Show answer
Insufficient Material Draws: separate an automatic dead position from a draw claim that depends on history or procedure. Candidate line: Ka3.
Why this position is here: Insufficient Material Draws is represented by a bare-king insufficient-material position. This is a direct FEN setup with board anchor 8/8/8/8/2K5/8/1k6/8; no opening history is inferred from the diagram.
FEN: 8/8/8/8/2K5/8/1k6/8 b - - 5 3
Question: What is the first concrete decision in this insufficient material draws position?
Answer cue: Insufficient Material Draws: separate an automatic dead position from a draw claim that depends on history or procedure. Candidate line: Ka3. The first candidate to test is Ka3. Replay Ka3 on board anchor 8/8/8/8/2K5/8/1k6/8 and write down what changes after it.
Evidence boundary: The position tests the stated rule or record field; verify the relevant source when a procedural decision matters.
Reading the record
Read the first example (id example-1) as a complete record: continuation Kb2, source fide-laws. This is a direct FEN setup with board anchor 8/8/8/8/8/2K5/8/3k4; no opening history is inferred from the diagram. If A does not expose a bare-king insufficient-material position, correct the evidence before relying on the prose.
Read the second example (id example-2) separately: continuation Ka3, source fide-laws. Its feature is a bare-king insufficient-material position; inventory side Black; pieces White king c4, Black king b2; legal first moves Ka3, Kc2, Kc1, Kb1, Ka1, Ka2. Compare what changes between Kb2 and Ka3.
Common confusions
The main mistake to avoid with Insufficient Material Draws is remembering a simplified slogan while overlooking a history field, exception or procedural condition. In A, the missing condition must be located in r1:8 | r2:8 | r3:8 | r4:8 | r5:8 | r6:2K5 | r7:8 | r8:3k4 after Kb2; in B, test it against r1:8 | r2:8 | r3:8 | r4:8 | r5:2K5 | r6:8 | r7:1k6 | r8:8 after Ka3.
For Insufficient Material Draws, the first board's evidence boundary (after Kb2) is The position tests the stated rule or record field; verify the relevant source when a procedural decision matters. The second board's evidence boundary for Insufficient Material Draws is The position tests the stated rule or record field; verify the relevant source when a procedural decision matters. If a trusted source or careful calculation changes the conclusion around the dead-position exception, update both the evidence record and this article.
Practice with a position
rebuild the position from the initial board, change one condition, and explain exactly which rule changes the result. Start with A's side to move and r1:8 | r2:8 | r3:8 | r4:8 | r5:8 | r6:2K5 | r7:8 | r8:3k4; record two candidates, the reply to Kb2 and the correction. Repeat with B's side to move and r1:8 | r2:8 | r3:8 | r4:8 | r5:2K5 | r6:8 | r7:1k6 | r8:8; the changed board tests transfer rather than diagram memory.
After the drill, compare your notes with The Fifty Move Rule, Dead Position Draws, Touch Move Rule through the arbiter's role in a claim. Keep A's rejected alternative beside B's chosen line Ka3; this shows whether the conclusion survived a new board signature.
