I need an extra trick to make 3nt from silent opps. I can get the extra trick from a 3-3 split in spades where I hold axxx-xxx, about a 36% chance. Or I can get a trick from jxx-qxx if both ace and king are on the same side. I have entries and enough stops in other suits, but I can’t try both without losing 5 tricks. Which option should I chose. I can’t find the odds of ace king being on the same side missing 7 cards
