I dealt and bid one heart with the following:
Left hand opponent doubled for takeout. Partner passed with something like K♦, Q♣ and one heart.
Right hand opponent held something like ♠Jxx ♥KT98xxx ♦void ♣Jxx and bid two hearts. It made, since the takeout doubler had some 18 points. I congratulated them on a good contract.
Would it have been better for RHO to pass for penalties instead? (No one was vulnerable). I always thought that a bid on the opponents' suit opposite a takeout double was a "cue" bid indicating a void, and slam interest, with prospectively 25-30 partnership points concentrated in three suits.
We were bidding a "loose" version of Standard American. So was two hearts a proper bid in this context? Or should it have meant something else?
