Doubles: Converting to Penalty

Sometimes partner makes a double for takeout, but you decide not to bid your longest suit because that’s the suit the opponent opened!

Have a look at this hand:

South has such extreme diamond length, it’s best to pass, converting what was meant to be a takeout double into a penalty double. The lead should be a trump, as the idea is to draw declarers’ trumps because the defenders have so many of them. If defended properly, the result will be 800 to North South. Ouch!
