  <legend>Responses to 1D Open for Beginning Precision</legend>
<p>Responses at the 1 level indicate that there is little or no possibility of game and are not forcing. If you have a 4-card or greater major suit, include distribution points to determine whether game is possible because it is not yet known if you and your partner have a fit in that suit.  For example, if you have 5 spades, a void in hearts, and 9 points,  bid 2 spades to show this possibility.  Even if opener has only 11 points but also has 3 spades, you have an excellent chance of making game by bidding the 4 level in spades.</p>

  <p>Responses at the 2 level are all forcing for at least 1 round and indicate an interest in reaching game level.</p>

  <p>The most frequent opening bid in Precision is 1 Diamond since it is the catch-all when nothing else applies. This is the best part of Precision. It is much more precise than its Standard Bridge counterpart, and because of this, the subsequent bidding is also much more precise! It does not tell your opponents much about what you have yet it tells your partner precisely what to bid next.</p>

  <p>This bid, like most Precision opening bids, should be alerted. If asked, explain: "11 to 15 HCP and no 5-card major, says nothing about diamonds".</p>

  <p>The strategy of the responder should be to immediately inform the opener that there is a possibility of reaching game by responding at the 2 level.  Secondly, look for a part score in a major. No dice? Settle for a cheap No Trump, or jump to a preempt in a minor when long and weak.</>

  <p>This bid, like most Precision opening bids, should be alerted. If asked, explain: "11 to 15 HCP and no 5-card major, could be short (as few as 2 diamonds)".</p>
  <p>We know that it rules out the "Weak 1 NT" hand. Thus, think of it as having 13 to 15 points, possibly resulting from a small suit distribution bonus.</p>
  <p>While strictly speaking this bid promises only 2 diamonds, that seldom happens since it denies 5 card majors, 6 clubs, and weak 1N.</p>

<h3>Responses</h3>

<fieldset class=" collapsible collapsed">
  <legend>1 heart - 4 hearts / 7-10 hcp, 5 hearts / 5-10 hcp, or 6 hearts / 0-10 hcp</legend>
  <p>Opener can rebid 1 spade with 4 spades and less than 4 hearts. You can then raise in hearts (with 3) if the responder comes back in NT. With 11-13 hcp, bid 1NT with 1-2 hearts. With 14-15 hcp, raise hearts with 3-4 card support. Responder should go to 2NT with only 4 in the suit, giving you the chance to raise spades to 3 to show the fit.</p>
  <p>With 14-15 hcp but no 3 card support, bid a 4 card spade suit or look for no trump starting in the minors. Bid the first minor in which you have a stop or 4 of the suit. Responder can show a 6+ card heart suit, show a stop in another suit, or bid 2NT to show stops in both of the other suits.</p>
  <p>The only case where it would make sense for opener to pass would be with bare minimum support of 3 hearts, no voids or singletons, and 11-12 points. This will invite the opponents to intervene, since your partner can continue at the 2 level with 5 or more hearts and upper hcp range if necessary.</p>

<fieldset class=" collapsible collapsed">
  <legend>1 spade - 4 spades/7-10 hcp, 5 spades/5-10 hcp, or 6 spades/0-10 hcp</legend>
  <p>Bid 1NT with 1-2 spades and raise with 4 spades.</p>
  <p>With 13-15 hcp, also raise with 3 card support. Responder can go to 2NT with only 4 in the suit, giving you the chance to raise again in case you have 4 also. Without 3 card support, bid your best minor so responder can show a 6 card heart suit, show a side suit stopper, or bid 2NT to show stops in both of the other suits.</p>
  <p>Opener may pass with bare minimum support of 3 spades, no voids or singletons, and 11-12 points. This will invite the opponents to intervene, since your partner can continue at the 2 level with 5 or more spades and upper hcp range if necessary.</p>

  <legend>1 no trump - no 4 card major, 5-10 hcp</legend>
  <p>Pass with 11-13 hcp or either a stop or 4 card length in each of the majors. Otherwise bid your best minor suit. Responder can bid a major to show a stop, pass with no stops in the majors, or sign off in 2NT with both majors stopped.</p>
