Everyone loves a slam and cool tools to find it.\u00a0 First we learned Blackwood 4 Notrump, then came Gerber 4 Clubs.\u00a0 Perhaps later we got the hang of cuebidding controls.\u00a0 Yet sometimes the bidding has revealed\u00a0our aggregate points are in slam territory if partner has an extra point or two.<\/strong><\/p>\n

Enter the Quantitative Slam Try.\u00a0 Just like in the inviting auction 1N – 2N, the sequence 1N – 4N ask partner to bid slam when holding a good 1 Notrump opener.\u00a0 In our Bridge blog and video commentary, we will dig deeper to explore this seemingly trivial bid.\u00a0 As always, partnership agreements can make a big difference when we are bidding some peculiar treatments.<\/strong>
\n\u00a0<\/strong><\/p>\n

Is it Quantitative 4 Notrump or Blackwood 4 Notrump?<\/strong><\/p>\n

1. Notrump Raise = Quantitative<\/strong><\/p>\n

2. 1N – 2C; 2H – 4N = Quantitative<\/strong><\/p>\n

3. No suit agreement = Quantitative<\/strong><\/p>\n

4. Suit agreement = Blackwood-ish<\/strong><\/p>\n

5. Self-sustaining suit = Blackwood (strong jump bids)<\/strong><\/p>\n

\u00a0<\/strong><\/div>\n

1N – 4N;
\n5D – ? <\/strong><\/strong><\/p>\n

Aces ? <\/strong><\/strong><\/p>\n

4 Diamonds “up the line” seeking 4-4 slam fit ? <\/strong><\/strong><\/p>\n

5 card suit?\u00a0 A better treatment is to respond 6D “Pass or correct” <\/strong><\/strong><\/p>\n

Non-Quantitative Examples <\/strong><\/strong><\/p>\n

(1H) – P – (1S) – 4N!\u00a0\u00a0\u00a0\u00a0 Unusual Notrump for the minors (likely 6-5 shape here) <\/strong><\/strong><\/p>\n

5 Notrump – “Pick a slam”<\/strong><\/strong><\/strong><\/p>\n

4 Notrump Ask Without Suit Control<\/strong><\/strong><\/strong><\/p>\n

Partner may have bid distributional points – Possible misfit <\/strong><\/strong><\/strong><\/p>\n

Missing Ace and King – Possibly two quick tricks outstanding <\/strong><\/strong><\/strong><\/p>\n

Opponents may or may not find setting suit – Feel lucky ?
