Contribution Information

Most people play Unusual 2NT to show the two lowest unbid suits. Its normal application is a jump over the opponent's opening bid.

We also play Unusual 2NT after they've bid and raised. However, it shows any two suits - not necessarily the two lowest. What if the bidding goes 1 - P - 2 and you hold


You'd hate to guess which suit to "balance" with. If you make a takeout double, you know that your dumb ol' partner will bid three diamonds.

So, we bid two notrump saying: "Partner, I have two suits - bid accordingly." If partner has 4-1-5-3 shape he'll start out with three clubs in response, knowing that, if you have red suits, you'll convert to three diamonds. If clubs is one of your suits you'll pass. Yes, if you have clubs and diamonds you'd be in your eight-card fit instead of your ten-card fit - but the objective of getting into these auctions is simply to find any fit.

Playing two notrump equals any two suits, and responding cautiously, we are able to sneak into the auction safely, confident that we'll be able to land in a playable trump suit.
