Quick answer
Theoretical Draws in Chess is an endgame technique: king-and-pawn geometry. Work from the first evidence position for Theoretical Draws in Chess, and begin by testing Kc1.
Begin from Kc1 in 8/8/8/8/2kP4/8/2K5/8 w - - 2 2. Count the material, king routes, promotion squares and reserve tempi before applying a theoretical rule. The evidence answer is: Theoretical Draws in Chess: count the king moves, the pawn's promotion square and the reserve tempo before pushing. Candidate line: Kc1.
In the Theoretical Draws in Chess example, notice: side White; pieces Black king c4, White pawn d4, White king c2; legal first moves d5, Kd2, Kd1, Kc1, Kb1, Kb2. The listed material and candidate moves belong only to this FEN example and should not be generalised.
Material and result question
The first evidence board tests king-and-pawn geometry; the second board tests king-and-pawn geometry. The first path uses direct FEN setup; the second path uses direct FEN setup as its setup string. Start from the Chess Wiki, then the Endgames hub, for nearby labels. Then compare Material Values with Stalemate In Endgames, Wrong Bishop And Rook Pawn, Knight And Rook Pawn around the defender's only active counterplay.
The two inventories make the distinction concrete. A contains side White; pieces Black king c4, White pawn d4, White king c2; legal first moves d5, Kd2, Kd1, Kc1, Kb1, Kb2; B contains side White; pieces Black king e7, White pawn d4, White king b3; legal first moves d5, Ka4, Kb4, Kc4, Kc3, Kc2, Kb2, Ka2. Compare the side to move before comparing the labels in the context of an outside passer used as a decoy.
Topic dossier for this page and board pair r1:8 | r2:8 | r3:8 | r4:8 | r5:2kP4 | r6:8 | r7:2K5 | r8:8 / r1:8 | r2:4k3 | r3:8 | r4:8 | r5:3P4 | r6:1K6 | r7:8 | r8:8: start with the defender's only active counterplay; then test an outside passer used as a decoy; keep the defender's fortress setup separate from the pawn's promotion square; use a reserve pawn move as the transfer check; and reserve the side-to-move tempo for the exception.
Conversion or defense plan
On the first board, calculate Kc1 after Kc1 and write down the opponent's best reply around the defender's only active counterplay. On the second board, calculate Kc3 after Kc3 and check an outside passer used as a decoy. 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 side-to-move tempo.
Key claim: Theoretical Draws in Chess is illustrated here by king-and-pawn geometry; the first concrete test is Kc1. The board anchor is 8/8/8/8/2kP4/8/2K5/8; 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 theoretical draws in chess, and how should each side play them?”, compare the recorded setup with Kc3 and the opponent's reply. The decision is useful only when the stated condition survives that concrete test on board 8/4k3/8/8/3P4/1K6/8/8. 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 | r2:4k3 | r3:8 | r4:8 | r5:3P4 | r6:1K6 | r7:8 | r8:8. The false-positive test is whether the defender's fortress setup appears without the pawn's promotion square, so the conclusion is useful only when the stated condition survives that concrete test.

Reading the line
Read the first example (id example-1) as a complete record: continuation Kc1, source tablebase. This is a direct FEN setup with board anchor 8/8/8/8/2kP4/8/2K5/8; no opening history is inferred from the diagram. If A does not expose king-and-pawn geometry, correct the evidence before relying on the prose.
Read the second example (id example-2) separately: continuation Kc3, source tablebase. Its feature is king-and-pawn geometry; inventory side White; pieces Black king e7, White pawn d4, White king b3; legal first moves d5, Ka4, Kb4, Kc4, Kc3, Kc2, Kb2, Ka2. Compare what changes between Kc1 and Kc3.
Boundary cases
The main mistake to avoid with Theoretical Draws in Chess 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 r1:8 | r2:8 | r3:8 | r4:8 | r5:2kP4 | r6:8 | r7:2K5 | r8:8 after Kc1; in B, test it against r1:8 | r2:4k3 | r3:8 | r4:8 | r5:3P4 | r6:1K6 | r7:8 | r8:8 after Kc3.
For Theoretical Draws in Chess, the first board's evidence boundary (after Kc1) is No tablebase outcome is asserted by this generated record; verify the exact FEN before publication. The second board's evidence boundary for Theoretical Draws in Chess 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 a reserve pawn move, 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 r1:8 | r2:8 | r3:8 | r4:8 | r5:2kP4 | r6:8 | r7:2K5 | r8:8; record two candidates, the reply to Kc1 and the correction. Repeat with B's side to move and r1:8 | r2:4k3 | r3:8 | r4:8 | r5:3P4 | r6:1K6 | r7:8 | r8:8; the changed board tests transfer rather than diagram memory.
After the drill, compare your notes with Stalemate In Endgames, Wrong Bishop And Rook Pawn, Knight And Rook Pawn through the pawn's promotion square. Keep A's rejected alternative beside B's chosen line Kc3; this shows whether the conclusion survived a new board signature.
