R.U.N.T. - the Really Unusual No Trump
Master Point Press author Ken Rexford provides the first authoritative description of the R.U.N.T. Convention. R.U.N.T. is actually a two-way overcalling structure to distinguish a very sound takeout double from a weak three-suited takeout by way of an artificial 1NT overcall - preempting and intervening in the auction safely and effectively.

Do you find a 4-3-3-3 hand with three Jacks a reason to sleep, or is this as good a reason to bid as any? You know who you are. Do you secretly enjoy declaring Two Clubs doubled, trying to find a fifth trick before the opponents find their ninth trick, instead of defending a boring 3NT? If you find it amusing to interfere with as many auctions as possible, this book is for you. Rexford introduces you to this effective and proven two-way overcall structure. With more advanced versions of the convention, you can add a very strong option, making the 1NT overcall almost a Multi type of takeout.

After all, bridge is supposed to be fun, right?
