part score and make 10 tricks in H you score \u00a0<span style=\"text-decoration: underline;\">+170\u00a0<\/span>\u00a0. \u00a0If you make 9 tricks you score \u00a0<span style=\"text-decoration:

better of making it.<\/p>\n<h2>Situation: \u00a0Bidding Non-vulnerable Games<\/h2>\n<p>Suppose you are trying to decide whether or not to bid 4H. \u00a0Let\u2019s look at your possible outcomes versus your actions.<\/p>\n<p>If you make 4H non-vulnerable you score<span style=\"text-decoration: underline;\"> +420\u00a0<\/span>. \u00a0If you go down one trick you score <span style=\"text-decoration:

it.<\/p>\n<h2>Situation: \u00a0Doubling them Into Game<\/h2>\n<p>Suppose you are trying to decide whether or not to\u00a0double their part score contract (assume 3H), where they will make a game if they make the contract.<\/p>\n<p>If you set them 1 trick and they are vulnerable\u00a0you score<span style=\"text-decoration: underline;\"> +200\u00a0<\/span>. \u00a0Set them two tricks and you score<span style=\"text-decoration: underline;\">\u00a0+500\u00a0<\/span>.<\/p>\n<p>If they make the contract you score <span style=\"text-decoration: underline;\">\u00a0-730 <\/span>.<\/p>\n<p>Assume you double the opponents in 3H while your teammates play the same contract undoubled, making the same number of tricks.<\/p>\n<p>If you beat it two tricks vulnerable while your teammates go down 2 undoubled, you win<span style=\"text-decoration: underline;\">\u00a0\u00a07\u00a0\u00a0I<\/span>MPS.<\/p>\n<p>If you beat it one trick while your teammates go down 1, you win<span

set.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The best way to understand IMP strategy is to look at the gains and losses for certain actions. \u00a0You will learn which risks have
