Lesson 9 Searching For Slams

  1. 1. Bridge Lessons - Intermediate<br />NYU Bridge and Spades Club<br />
  2. 2. Lesson 9<br />Searching for Slams<br />
  3. 3. Point System for Slams/Grand Slams<br />500/750 (NV/vul) points for slam (6-level contract bid and made)<br />1000/1500 (NV/vul) points for grand slam (7-level contract bid and made)<br />For both kinds of contracts, add the 300/500 point game bonus as well<br />The point bonus for slams and grand slams is very huge. Thus, knowing how to search for them is very helpful.<br />
  4. 4. Cue Bids<br />After a suit has been agreed upon, one may initiate a slam try using cue bids<br />Cue bids show 1st or 2nd round control in the suit bid i.e. A, K, void or singleton<br />E.g. 1H – 3H – 4C is a cue bid showing 1st or 2nd round control in clubs<br />Most of the time, whether a bid is a cue bid is based on common sense. Usually after a fit has been established, there’s not much of a point showing another suit. Shortness is generally more helpful<br />
  5. 5. 4NT Blackwood<br />Given that 3NT is a game level contract, the 4NT bid is otherwise quite useless. Hence, bridge players have come up with an alternative use for it – to ask for aces.<br />After a suit has been established, bidding 4NT can be treated as Blackwood. The replies are as such:<br />5C = 0/4 aces<br />5D = 1 ace<br />5H = 2 aces<br />5S = 3 aces<br />After the reply, Blackwood bidder can opt to bid 5NT to ask for kings as well<br />
  6. 6. RKC 4NT<br />Modern bridge players feel that Blackwood asks for too little, and have thus come up with the Roman Key Card 4NT bid.<br />The key cards are the 4 aces and King of trump<br />Replies:<br />5C = 0 or 3 of the key cards<br />5D = 1 or 4 of the key cards<br />5H = 2 or 5 of the key cards, denies Q of trump<br />5S = 2 or 5 of the key cards, confirms Q of trump<br />This is known also known as the 0314 convention<br />Some (including myself) choose to invert the 5C and 5D bids (this is known as 1430). See the next section for the reason<br />
  7. 7. Rebids after RKC 4NT<br />School of thought 1: bid 5NT to ask directly for number of outside (non-trump) kings<br />School of thought 2: bid 5NT to ask for specific kings<br />School of thought 2: bidding 5NT confirms possession of the Q of trump and asks for specific kings. However, another bid can be made to ask for the Q after 4NT – 5C/D.<br />
  8. 8. Rebids after RKC 4NT – School of Thought 1<br />5NT asks for Kings in a similar fashion to Blackwood<br />6C = 0 kings<br />6D = 1 king<br />6H = 2 kings<br />6S = 3 kings<br />This allows the RKC bidder to ask for the most information. Unfortunately, this also means singletons are diminished in importance, the Q trump is of no importance and may result in overbidding e.g. 6H reply when requiring all the kings to make 7D (D is agreed suit)<br />
  9. 9. Rebids after RKC 4NT – School of Thought 2<br />To circumvent the problem in the first school of thought, some bridge players opt to ask for specific kings<br />5NT asks for partner to bid a specific outside king at the 6th level e.g. in hearts contract with diamond king, bid 6D<br />With 2 or more outside kings, partner will bid grandslam directly. With no outside kings, partner will bid slam directly<br />This may also lead to problems when partner is holding spade king in a hearts contract<br />
  10. 10. Rebids after RKC 4NT – School of Thought 3<br />5NT rebid guarantees possession of the Q of trump<br />Without Q of trump, bid the next cheapest bid to ask for Q of trump and specific kings<br />E.g. 4NT – 5C – 5D is asking for Q of trump and for specific kings.<br />You cannot bid the next cheapest bid if it is the agreed suit e.g. 4NT – 5D – 5H with H as agreed suit is a stopping bid, not an asking bid<br />Without the Q, partner bids the contract at the 5 level. After this bid, you may still choose to use 5NT to ask for specific kings, though generally the right contract here is the slam, not the grand slam<br />
  11. 11. Rebids after RKC 4NT – School of Thought 3<br />With the Q, partner will bid a specific king<br />E.g. with outside K club with hearts as agreed suit<br />4NT – 5D – 5S – 6C shows Q hearts and K club<br />Notice H was skipped as it is the agreed suit<br />With &gt;1 king, partner should bid the cheapest king<br />E.g. with outside K spades and clubs with hearts as agreed suit<br />4NT – 5C – 5D – 5S shows Q hearts and K spades<br />After partner’s specific king bid, you can bid another suit to ask for king in that suit. E.g. after 4NT – 5C – 5D – 5S, if you need K club to make grand slam, bid 6C. Partner can then bid the grand with the K club or slam without<br />Primary benefit of this school of thought: more discussion at a lower level. Also, when missing one key card, the partnership can decide if a slam is still makeable by asking for Q trump<br />
  12. 12. Reason for using 1430 vs 0314<br />In general, you are more concerned about whether partner has the Q of trump when partner has only 1 key card, not when partner has 0 or 3 key cards. In general if partner has 3, you’re making grand; and if partner has 0, you’re not going to slam.<br />Thus, using 5C as 1 or 4 is more helpful as 5D can be used as the Q asking bid. In hearts contracts especially, you can see the difference. 4NT – 5D will lead to an inability to ask for Q hearts without going to slam level<br />
  13. 13. Gerber (revision)<br />Works over NT openers and some NT rebids<br />4C bid<br />Partner bids 4D with 0/4 aces, 4H with 1 ace, 4S with 2 aces or 4NT with 3 aces<br />
