AI as a Consultation Tool — Impact of AI on the World

As is well known, AI has transformed multiple sectors across all branches of knowledge in a vast and multifaceted way, delivering significant benefits in efficiency and quality of life, but also presenting challenges that require careful attention. Concerned about the feasibility of AI becoming a tool that could resolve any problem in the game of BRIDGE regardless of its complexity, potentially affecting readers’ interest in consulting my books, I dedicated myself to researching its effectiveness. I began my research by asking ChatGPT the following question "I need an expert in the game of BRIDGE." ChatGPT responded: “Sure! Please provide the details of the hand or situation you want to analyze. To help with the bidding I need: The hands of the players, at least the opener and partner (better if all four). Vulnerability? (vulnerable, not vulnerable, or one side vulnerable while the other isn’t). Who is the dealer? (North, South, East, or West). Which bidding system do you use? (e.g., SAYC, 2/1, natural, Precision, etc.) Pairs, IMPs, or rubber bridge play? (This changes the strategy). Once you provide that, I’ll give the correct or possible bidding line with an explanation. Go ahead with the data.” Shape The User’s Provided Hand (Translated) The system is SAYC. All vulnerable. The opponents are not interfering. Here is the hand: OPENER ♠ xx ♥ Axx ♦ AQx x ♣ KQJx RESPONDER ♠ xx ♥ KQJ10xx ♦ KJx ♣ Ax ChatGPT said: “Thanks, now with the two hands complete, the context is clear.” Shape System, Context, and Players System: SAYC All vulnerable No interference Players: Opener (the one who opens) ♠ x x ♥ A x x ♦ A Q x x ♣ K Q J x Responder (partner of the opener) ♠ x x ♥ K Q J 10 x x ♦ K J x ♣ A x We will now analyze step by step how the auction should proceed under SAYC, which is a natural bidding system with a 1NT opening at 15–17 HCP and with the use of basic conventions such as Stayman, Blackwood, etc. Shape Step 1: Point Count Opener: High card points (HCP): A = 4, K = 3, Q = 2, J = 1 ♥A (4), ♦A (4), ♦Q (2), ♣K (3), ♣Q (2), ♣J (1) = 16 HCP Distribution: 2-3-4-4 Responder: ♥K (3), ♥Q (2), ♥J (1), ♦K (3), ♦J (1), ♣A (4) = 14 HCP Distribution: 2-6-3-2 Total combined: 30 HCP = Slam strength! Shape Step 2: The SAYC Auction Development 1♦ — Opener’s Opening He has 16 HCP Opens 1♦ for ♦AQxx (4 cards) and not having 5 clubs to open 1♣ He cannot open 1NT (16 HCP but with 2-3-4-4, and ♥A x is not ideal for NT) 2♥ — Responder’s Response 14 HCP + a good 6-card ♥ suit → strength to change level; forcing No jump to 3♥ because in SAYC that would be invitational, not forcing Therefore, he responds 2♥ (new suit at the 2-level: forcing for one round) 3♣ — Opener’s Rebid Shows his 4-4 in minors Not supporting ♥ yet because only has 3 cards Does not repeat ♦ because he already showed it 3♣ shows a minimum hand (not jumping), but with values and distribution 3♥ — Responder’s Rebid Repeats his ♥ suit = at least 6 cards and hands with slam strength (remember that in SAYC 3♥ now is forcing because the auction is already forced) Invites exploration of slam if the opener has good support 4♥ — Opener’s Support With 3 ♥ cards (Axx) and 16 HCP, now can support and close at the game level Doesn’t want to jump to 5♥ or use Blackwood yet 4NT — Blackwood by the Responder There is already a fit in ♥, 30 HCP combined Uses Blackwood (4NT) to ask about Aces 5♦ — Opener’s Response (two Aces) On Blackwood scale: 5♣ = 0 or 3 aces 5♦ = 1 or 4 aces 5♥ = 2 aces without the king of trump (trump king) 5♠ = 2 aces with the king of trump Here there can be some confusion: in SAYC, most use the version where 5♣ = 0 or 4, 5♦ = 1, 5♥ = 2 without the king of trump, 5♠ = 2 with the king of trump The opener has: A♦, A♥ = 2 aces, and also has K♥ → Therefore he should say 5♠ 6♥ — Responder Signs Off in Slam He knows they have 2 aces + K♥ No problems in ♠ 6♥ is the final contract Shape Complete Expected Auction Opener Responder 1♦ 2♥ 3♣ 3♥ 4♥ 4NT (Blackwood) 5♠ 6♥ Pass Shape FINAL CONTRACT: 6♥ 30 HCP TOTAL STRONG HEART FIT (9 CARDS) CONTROL IN ALL SUITS EXCELLENT SLAM; VULNERABLE Shape Noted Issues and Corrections As can be seen, the information is RIDDLED WITH ERRORS: The correct opening is 1NT: 15–17 HCP with controls in at least three of the four suits and without a SINGLE or VOID There is no control in the spade suit in either hand The slam cannot be achieved with a spade lead The correct auction, following the instructions indicated in Chapter 2, BOOK 3, is as follows: OPENER ♠xx ♡Axx ♢AQxx ♣KQJx REPLY ♠xx ♡KQJ10xx ♢KJx ♣Ax OR 1NT 2♢ 2♡ 4♣ 4♠ 5♣ 5♢ 5♡ P 2♦: Transfer to hearts 2♡: 15/16. May have support doubleton or third with a minimum hand or strong with controls in all suits or an unprotected suit, or a strong hand with a doubleton 4♣: GERBER. Strong hand with slam intent. Sixth suit with at least two high honors. There is a fit. The opener must have at least a doubleton. 4♠: 2KC 5♣: ARTIFICIAL. Shows the Ace. Any response by the responder or the opener after the Ace bid shows the Ace. It must always start with the lowest-ranking suit. May also have the Ace of Diamonds or the Ace of Spades. 5♦: Has the Ace of Diamonds. Does not have the Ace of Spades. With the Ace of Spades, would declare SLAM. 5♡: SIGN-OFF. HAS NO CONTROL IN SPADES. KNOWS THEY WILL LOSE TWO TRICKS IF THE LEAD IS IN THIS SUIT.
