Akiba Rubenstein was playing in a tournament and had the point lead with one game to go he was playing against Wolf and needed a draw to win the tourney. about 15 moves into the game Wolf offered Rubenstein the draw. Akiba declined and played on till he had a slightly superior position then offered Wolf a draw, which Wolf gladly accepted. After the game Akiba was asked why he declined Wolf's draw offer and then played on till he was winning then offered a draw to Wolf. Rubenstein's reply was with Wolffe I draw when I want to not when he wants to.
