or a 10xx A A combination. or a xxxx A A combo. Note also that pard will PULL 3NT without 2 aces, so it's a fairly safe bid, the only risk being going 1 down in 4♣. Some people play 3N in 3/4 seat cannot be pulled. That is how I play. When I play Gambling 3N, this is how I play it as well. The restriction on no A/K is only in 1/2. Me too. I'd not be happy seeing partner pull when I've got 9 tricks on my own.
