on playsite.com i was playing a bg match for 3 points, the score was 1-1 .. my opponent was slightly ahead in pips .. and he had 2 pieces at my #1 and in a few turns would probably have a chance to capture me while his home was completely blocked ... i didnt want to risk this and offered a double as i hoped he would decline and give me a 2-1 lead with a crawford round, so i had 2 rounds to score a point
in his case i would have accepted the double though .. as the game was (imo) quite balanced at that point and i would have hoped to win the match with it
he declined though .. and i won the next round, and the match
