THINK TWICE/PUZZLE ME TWICE (edition 1)
p24
Between line 5 and 6 a sentence has been missed out. From line 5 that paragraph should read:
‘Both hands will beat all other full houses, because no other hand can have three aces. Both hands eliminate the same number of fours of a kind, and eliminate royal flushes in hearts, diamonds and spades. But hand b) eliminates more straight flushes. For example, if you have hand b), you have the 9 of hearts and of spades, which means your opponent cannot have a run of cards in hearts or spades of 5 to 9, 6 to10, 7 to jack, and 8 to queen. If you have hand a), the only straight flush in hearts or spades that your opponent cannot have is 9 to king.’

The solution for saving the French sailors is a = 7, b = 29.
