Diana Chess
Diana, also known as Ladies’ Chess (Hopwood, 1870). This game, published in the recreation supplement to The Gentleman’s Journal (August 1870), is ‘chess rendered easier, especially adapted for our fair friends and also for draughts (checkers) players who may not have time to cultivate the more ancient game ... a game which could be played in half an hour and which may, at the same time, be superior to draughts as regards difficulty and ingenuity’. Hopwood’s contention was that the queen and the knights (‘in the management of which ... Morphy stands pre-eminent’) were too difKcult to handle for ladies and draughts players. Board 6x6; baseline (a1-a6/f1-f6) RBNKBR; pawns move one square only, promote to any array piece; kings castle under usual restrictions by changing places with rooks.
