【N-S南北為山嶺嶺山學員】
第四家位置，手持如此破的12點（高花有Qx、Jx雙張的廢點），且雙高花都是短套，不符合15法則開叫：12+2＜15。在最後一家位置上，更好的選擇是Pass，避免吃到負分。
開叫1D後，果然遭遇敵方黑桃套爭叫，S家以4個H做負加倍，但南北方卻陷入了失配的尷尬境地！
At 4th seat, holding bad 12 count, with Qx and Jx doubletons in both majors (may be wasted), the hand doesn’t meet Pearson Rule of 15 (12+2 < 15), it is best to pass.
After opening 1D, the 1S overcall was not unexpected, South made a negative double, North-South side was heading for trouble due to misfit.
客觀分析，開叫選擇的錯誤還可以原諒，但S家第二口的再叫錯誤非常嚴重！
請問，同伴再叫2C就一定是低限嗎？同伴持有14+大牌點時，難道還必須跳叫？
真的看不懂！手持10個HCP，而且10領頭的5張S，為什麼不叫2NT?If opening North hand is only a minor mistake, then South’s final pass is a more serious one. The 2C rebid by opener is not necessarily minimum, what if opener has 14+ HCP (but not enough to jump shift)? Holding 10 HCP and 5 spades to the 10, South should have bid 2NT.【開室E-W為山嶺嶺山學員】
開室W家學員的叫牌又是犯了防守競爭叫牌中低級錯誤。
同伴作一蓋一的爭叫後，如果S家不叫，你應叫1NT是為了防止同伴的爭叫可能持有高限充沛的牌點，錯失了成局的機會。不是為了顯示同伴的爭叫花色你缺乏支持，想去修改這個爭叫花色！
In the open room, West also made a basic mistake in competitive bidding. After partner overcalled at one-level, if South hadn’t bid, you would have bid 1NT in case that partner had maximum value and you wouldn’t want to miss game. It would not be an attempt to improve the contract due to misfit.
現在南家做了Negative Double之後，W家完全可以放任不管，靜候著對手艱難地去尋找最後的定約，或許這正是你夢寐以求的最好結果。
可惜我們這些初出茅廬的小學員，童心未泯，只有強烈的衝殺激情，還沒學會靜觀其變的謀略，克制、忍耐、後發制人、一招制敵的本領！
Now that South made a negative double, West was no longer obligated to bid. West should have passed, watching the opponents to struggle in whatever contract they may reach. Unfortunately, the junior blood sometimes leads to foolhardy and less rational actions.
