Part 1 2nd in hand, you hold ♠-♥AKxx♦K9xx♣AK10xx RHO opens 2♦ (weak); what's your choice? [you are at red, playing pairs, if it matters] Part 2 Having chosen 2NT in part 1 (if you find that morally repugnant, please just follow the usual formula, i.e. you have been called in to fill in for someone who has left the table mid-auction for some sort of emergency), the auction continues (no interference) (2♦)-2NT-3♥ 3♠-4♥ ??? Partner's sequence is defined as 5-5, non-forcing but with slam interest (he can show three tiers of major 5-5: game only, this one, and slam-force) What is your choice now?
