Two Over One - Introduction
In the so-called ďTwo Over OneĒ (aka 2/1) style of bidding, an auction such as 1♥ 2♦ is game-forcing. Opener starts with one of a major, and Responder bids a new suit at the two-level, and the force is on. But not if the new suit at the two-level is a jump Ö an auction such as 1♥ 2♠ is a jump shift, and not the start of a 2/1 auction.
As Responder, in this style, you basically need opening values to venture into a 2/1 auction. What are you supposed to do if you have a good but less than game-forcing hand? If you have support for Partnerís major, then the problem is solved. But, with less than game-going values, and without support, you must bid the Forcing No Trump. Thus, in an auction which starts 1♥ 1NT, or 1♠ 1NT, Responder might actually have a pretty decent hand, just one which is not good enough to force to game.
Based on the above scant information, it might seem premature to present you with a Quiz, but sometimes getting thrown into the deep end is a good way to see if you can swim. Partner opens 1♥, itís your call:
♠ 65 Not quite a game force, so bid the Forcing 1NT.
♠ KQ65 No, you donít bid the Forcing No Trump if it means
♥ 87 by-passing a 4-card major. So, bid 1♠ here.
♠ KQ65 Here we have the values to make a 2/1 bid, and that is
♥ 87 exactly what you should do. Bid 2♦, create the force,
♦ AKJ54 and get those Spades into the auction later.
♠ 65 Forget about the Forcing No Trump here, you must clearly
♥ AK87 raise Partnerís Hearts, one way or another, depending upon
♦ QJT84 your methods.
♠ 5 It may seem strange to bid 1NT with a singleton in an
♥ 87 unbid suit, but that is exactly what you should do.
♦ KJ654 Remember that the Forcing No Trump does not show a
♣ AQ743 balanced or No Trumpish hand Ö it merely says that you
have no other bid available.
♠ 876 When we make a 2/1 bid we normally show a 5-card
♥ 76 suit, but sometimes we just have to stretch the truth a bit.
♦ AQ84 So, bid 2♣ here, creating the force. Bidding some number
♣ AKJ2 of
No Trump here, with that Spade holding, is not a good
For the time being, at least, letís keep things simple. Just make all bids natural and descriptive. So, after a start of 1♠ 2♣, try the following hands:
♠ AQJ654 Bid 2♠, showing a 6th Spade.
♠ AQ9654 Yes, get that 4-card Heart suit into the auction, you can
♥ KJ65 always show your extra Spade on the next round of
♦ Q6 bidding.
♠ AJ964 Should you raise Partner or bid 2♥? We would bid 2♥,
♥ AJ95 hoping that weíll get the chance to bid 3♣ later. As
♦ 8 usual, in the search for the best game, we emphasize the
♣ K75 majors.
♠ AJ964 Yes, this looks like a 2NT rebid to us!
♠ AJ964 Some players (us included) would have opened this 1NT
♥ KJ7 originally, but if you donít like to open 1NT with a 5-card
♦ KJ7 major then, after 1♠ 2♣, you have a perfect rebid of 3NT.
