This Week in Bridge Practice Hands
Fundamental Notrump Bids - 1M - 3NT* a Good 1M - 4M Bid
In general, we use jumps in competitive auctions as weak bids (0-5 points) applying the Law of Total Tricks (LOTT) -- (though sometimes the modern approach can be to use mixed bids, 6-9 points). The key is that we jump to our Law level, eating up bidding space, to quickly and narrowly define our hand.
