Opening tables

English Draughts 8×8

The 174 official English Draughts 8×8 openings, with their strength code and the federal table they belong to.

174Opening

In official play the first three half-moves are not chosen but drawn from a table. The general table holds all 174 openings; the federal tables A, B, C and D are subsets of it, used depending on the kind of match.

In a direct challenge you can cap the draw by strength: up to 2N/2B a single game still counts for the rating, above that you need a two-game match.

How to read the strength code
  • PARI PARI — even game.
  • 1N/1B 1N / 1B — that colour is slightly better, with more choice of lines.
  • 2N/2B 2N / 2B — that colour is clearly better and the opponent plays defensively.
  • 3N/3B 3N / 3B — that colour is formidable: the opponent needs expert play to draw.
  • 4N/4B 4N / 4B — that colour is considered winning with current knowledge.

N = Black (Nero), B = White (Bianco).

Why 302 openings become 174

There are 302 legal three-half-move openings, but they only reach 216 different positions: the general table picks 174 of them, one per position. Here is what happens to the rest.

Listed174Drawable: one of the official openings.
Transposition72Same final position as an opening already listed, reached by playing the moves in another order: it would be the same game under a different name.
Loses a man2After the third half-move one side is a man down with no recapture: these are the two combinations the regulation has always excluded.
Not listed54A position the table does not cover at all. There is no mechanical reason: the federation selected the lines worth studying.
Table D18Still listed, but for two-game matches only: they are considered winning for the favoured colour, and therefore losing for the other.
