Takeout doubles and negative doubles are two sides of the same coin — both say 'I want to compete, partner, pick a suit.'

But the situations that call for each one are completely different.

In this workout, Coach Ace breaks down the requirements for a textbook takeout double, how to respond when your partner doubles, and how negative doubles (made by the responder after an opponent overcalls) keep you in the auction when you'd otherwise have to pass.

You'll drill 10 hands that put you on both sides of the auction — and walk away knowing exactly when a double means business.
