Pawnless Chess Endgame - Tables

Tables

This a table listing several pawnless endings, the number of moves in the longest win, and the winning percentage for the first player. The winning percentage can be misleading – it is the percentage of wins out of all possible positions, even if a piece can immediately be captured or won by a skewer, pin, or fork. The largest number of moves to a win is the number of moves until either checkmate or transformation to a simpler position due to winning a piece. Also, the fifty-move rule is not taken into account (Speelman, Tisdall & Wade 1993:7–8).

Famous quotes containing the word tables:

    “The word unto the prophet spoken
    Was writ on tables yet unbroken;
    The word by seers or sibyls told,
    In groves of oak, or fanes of gold,
    Still floats upon the morning wind,
    Still whispers to the willing mind.”
    —Ralph Waldo Emerson (1803–1882)

    “It breedeth no small offence and scandal to see and consider upon the one part the curiosity and cost bestowed by all sorts of men upon their private houses; and on the other part the unclean and negligent order and spare keeping of the houses of prayer by permitting open decays and ruins of coverings of walls and windows, and by appointing unmeet and unseemly tables with foul cloths for the communion of the sacrament.”
    —Elizabeth I (1533–1603)

    “The evening falters. Couples in their coats
    Are leaving gaps already, and the rest
    Move tables closer.”
    —Philip Larkin (1922–1986)
