IVAN CY LO

曾經手持一手牌 S:XX H:- D:AQXXXX C:AQXXX Partner 開叫1D, 右敵爭叫1S，我想也不用想就立刻扣3S，基乎肯定不是3NT 就是5D，扣叫3S 結果是OPP 問不出H，3NT+3。如首引H，3NT 立即宕。

第一副，持有OPP SUIT 的次級大牌時應保守。手上是5332 平均牌型輸張太多，2H 即使同伴有3張H支持也有可能宕2或宕3，如對方並無配合根本難以成局。在防守競叫時大牌點不是考慮因素，輸張及主打贏楝來源才是首要。 第二副，總楝數定律告訴我們何時該叫上局，我是打SAYC 此牌我會叫3H 讓同伴考慮進局。反而如是6張將牌高限，則可考慮直接進局。 第三副，同伴低限手上控制不是太好，進局希望多是3NT 而不是4H。 三副牌胡亂叫牌都是因為只懂高倫的大牌點計算，而對於加羅佐的藍梅花中的7/9/11 控制(GAME/SMALL SLAM/GRAND SLAM)，總楝數定律及輸張計算認識太少所致。

明手11點，手上6點，合共17點，莊家沒有開叫1NT，應該是11-14點之間，預期同伴有8-12點，莊家手上已露SK，同伴露出DA，莊家必需持有HKQJ，DKJ，SK 才夠開叫實力。 SA 明顯地在同伴手上。 回紅心2必須馬上HA吃進，再回攻S9 的中間張解封。

If double is penalty, 4NT is takeout, I would choose to pass or double. Quite obvious that P having 0-3/4P if South has opening hand and north free bid at 2 level. 5 level minor contract expects to loss 2H, 1S 2-3 club.

首先PASS，等東西叫出♣後扣叫♣。這手牌南北有♠配合9張東西最少有♣配合8張。TAKEOUT 以後9成以上東西會叫出♣。如他們沒叫出來，則先停一下想想滿貫希望。PARTNER 極有可能是持有4張以上♣，♣有廢點，滿貫難於想像。

我跟固定partner 約定3h 跟3d 的分別是。 3d: 持有不堅固的6張d套 3h: 持有堅固的6張以上的d套，最少是AKQXXX，若H 有一檔，請叫3NT。 如持有KQJXXX，絕對不能叫3H 作詢問性的3NT，必須是堅固的6張套的3D 才可叫3H。

對於小多義2D(僅限於高花阻擊一途)，後續叫牌是簡單的，先談一下小多義2D 的後續 假設對方沒有插叫時。 2♦ - X X = 2♥，弱牌，PASS OR CORRECT to 2♠ = 2♠，紅心有支持，不代表有黑桃，開叫實力。如開叫者叫回2NT 則PASS，3♥是邀請。 = 2NT，好牌問叫，如開叫人高花夠贏楝時則準備打3NT，不夠時可打4階高花，最差也迫叫至3階高花，這時開叫人答3♣ = ♥弱套 ，3♦ = ♠弱套 ， 3♥ = ♥強套，3♠ = ♠ 強套，3NT = AKQXXX 在高花。註，如是多功能2♦，則需要約定19+4441 及20-21 對2NT 應叫的答叫。 = 3♣，自然叫同等轉換，7張♣以上，低於開叫牌力 Pass = ♦ 套，高花不支持。 大多義由於包含19+ 4441 特殊牌型或20-21 2NT，在2♥應叫後叫3階則是大多義19 +4441 ，所叫花式為單張-1級的花色，如♠單張則叫3♥，2NT = 20-21 強牌。STAYMAN 及TRANSFER 等可自行約定。 基

I play negative free bids with partner at 2 level, he can bid a 5 cards suit with just 7HCP at 2 level because it is a negative free bid. My system with partner after overcall always cue-bid = game forcing, 2M after overcall = negative free bids, around 7-10 and 5 cards in M. Double = forcing for 1 round and asking 4 cards major, obviously no 5 cards suit (around 7-10). Double and then bid a suit, 11+ with a game inv. value, 4 cards. With this system partner pass after overcall, usually he has a crap hand with below 8. Game isn't our concern but we need to find a suit fit to compete. NT overcall usually showing 18-19, but we don't play overcall 2NT, usually is 1♦ - 1♥ - Pass - Pass - 1NT(18-19). It is no sense to rebid a 2NT as we played direct openning 2NT = 20-21, 2C = 22+. If partner holding a 0 points crap hand, re-bid 2NT will be disaster and giving opp. 200-500 depends on vul. Usually this hand partner pass overcall 2C, I will bid based on my hand and assuming he has crap. 2♦ will be my first choice. If my partner correct to any M after 2♦. It is not a forcing but saying that we don't have fit in ♦. With 2 cards in ♥ and 3 cards in ♠, I can accept his any correctness after 2♦. If jump shift in new suit after 2♦, it is not likely to happen but this means an extra length(7+) and few count in strength.
