NoTrump, which is a bid used in the card game bridge. A bid of
1NT (One Notrump) means that you (together with you partner) expect
to win one trick or more if the game is played without a trump
the NT bids often mean other things, depending on which bidding system
you use. For example, the bid 4NT is often used as a question to your
partner about how many aces he/she has on hand (see Blackwood).
