Short answer: Both Richelieu and Warspite (per post #7502059)

Long answer: It's a Quinella bet, which is a bet where betters pick two runners that they think would come in the top two.

He went quinella on Darjeeling Scone and Macaron Madeliene.

Which is to say he betted on Warspite's and Richelieu's horses finishing first and second in any order.
