Card game with limits on pack, reportedly? (6)
I believe the answer is:
piquet
'card game' is the definition.
(I know that piquet is a type of card game)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for piquet that I've seen before include "Card-game with 32 cards" , "Card game with 32 cards" , "patrol" , "Card game for two" , "Racing driver" .)
