Your partner opens the bidding with 1 and you hold:
K J 4 A 9 5 4 Q Q 10 8 4 2
As responder you need to ask yourself – what is the ‘worth’ of my hand, how do I best describe my hand, how do I think the auction will develop and to what level? This is why chess players make good bridge players because they have the ability to think out the several moves ahead not just the one at hand.
So, what is your hand worth, do you have 12 HCP? Do you just blithely bid 2, or do you discount your singleton Q and bid 1. Are you are strong enough to force to game? Do you show your 4- card major in preference to your 5-card minor?
So you bid 2, and now what does the opener (your partner) think you have? You bypassed the majors, so you denied (on the surface) holding four cards in either of these suits and you have 10+ points as you bid a new suit at the 2-level. If the opener now bids 2 is this a reverse bid, showing a strong hand of 16+ points, or do you play this as just an ongoing description bid? This last question is a matter of partnership discussion. When this hand came up in our club teams’ championship, I would have preferred that my partner had bid 1 rather than 2, because as the opener I now showed my 4-card heart suit, unsure as to whether I was making a reverse bid or not. My partner now bid 4. Before North lead 10, he asked East if my 2 was a reverse, and guess what the answer was? Yes, of course … well, I didn’t have my bid then and as dummy was displayed, he said “don’t make too many tricks.” I just made my 10 tricks, losing one trick in each of spades, hearts and clubs.
