TOKYO STANDARD GOULASH BIDDING
For players at Bridge Base Online (BBO) Goulash tables who have encountered highly aggressive, precisely calibrated bidding structures that completely bypass traditional Standard American (SAYC), 2/1, or Precision methods, this document serves as a summary for the system known as "Tokyo Standard Goulash Bidding”.
SYSTEM OVERVIEW & ORIGINS:
This distribution-driven system was developed and optimized through trillions of computer hand simulations by a team of game-theory programmers in Tokyo and tested by a user billgw26. It is designed specifically to maximize expected value (EV) under the extreme, warped card distributions unique to Goulash deals.
WHY TRADITIONAL BRIDGE BIDDING SYSTEMS FAIL IN GOULASH:
Standard bridge systems rely on a normal statistical bell curve, assuming flat hand shapes where High Card Points (HCP) dictate defensive tricks. Tokyo Standard Goulash recognizes that in extreme deals, traditional point-counting and takeout doubles collapse. Further, bridge bidding conventions are designed for game level contracts whereas Tokyo Standard Goulash Bidding is designed for slam and grand slam bidding. By implementing a strict "Pure HCP" initial baseline, using pure penalty doubles after 3NT, utilizing advanced Game Theory Optimal (GTO) passing traps, and slow upwards bidding, this Tokyo Standard Goulash bidding system outperforms standard bridge methods. A summary document below is for the global goulash community.
CORE EVALUATION PRINCIPLES & STRUCTURAL RIGIDITY
1. PURE HCP EVALUATION: Opening and competitive decisions are initially based strictly on High Card Points (HCP). Voids, singletons, and doubletons are completely ignored on the initial round of bidding.
2. VULNERABILITY IGNORED: System parameters, point ranges, and suit lengths remain 100% identical regardless of table vulnerability.
3. ZERO 4TH-SEAT LEEWAY: Traditional balancing/protecting is strictly forbidden. If passed to the 4th bidder, a hand with 12 HCP and a 7-card suit is a mandatory PASS, forcing a pass-out. Frequently, an opponent may have trapped pass.
4. DEFENSIVE CARDING: Uses standard signals (e.g., discarding a low card to signal defensive interest/length in a lower-ranking suit visible in the dummy).
5. OPENING BID ZONE MATRIX
a. 1-LEVEL SUIT: Shows 13–20 pure HCP with a primary natural suit.
b. 1NT OPENING: Shows 14–18 pure HCP. Unbalanced/"funny" distributions okay.
c. 2NT OPENING: Shows 20–21 pure HCP. Unbalanced/"funny" distributions okay.
d. 2♣ OPENING: Shows 21+ pure HCP, game-forcing.
e. WEAK 2/3♣: Shows 4–12 pure HCP and an exact 8 to 11-card suit (2♦, 2♥, 2♠, 3♣)
6. COMPETITIVE OVERCALLS & RESPONSES
a. THE "JUMP 8 OVERCALL": A jump over an opponent's opening bid promises 4–12 pure HCP and an 8 to 11-card suit. Operates at any level (e.g., bidding 6♥ over an opponent's 5♦ opening with a 9-card suit).
b. RESPONDER JUMP 8: If partner opens a weak 2 and opponents bid, a responder holding an 8 to 11-card suit may execute a Jump 8 action of their own, bid 4NT or support partner’s suit.
c. UNUSUAL 2NT OVERCALL: Bidding 2NT over an opponent's 1♥ or 1♠ opening shows a constructive hand with both minors (at least 5-5 distribution).
7. FIRST-ROUND PASS TRAPS (GO SLOW)
a. THE SUB-4 HCP TRAP: If holding an 8 to 11-card suit but under 4 pure HCP, you must PASS on the first round and enter the bidding with a jump 8 overcall, or support partners suit, or pass on round two.
b. THE SUB-MINIMUM TRAP: If you are the first person to bid holding exactly 12 pure HCP with a 7-card suit and a side void, you must PASS on the first round and enter the bidding on round two.
c. THE 12-CARD SUIT ULTIMATE TRAP: - 1st Position: Always PASS to conceal shape and gather table information, 2nd/3rd/4th Position (unopened): PASS to maintain trap, or leap directly to 4NT or 6-of-the-suit.
8. CORE BIDDING MECHANICS & RESPONSES
a. DOUBLES after 3NT are PENALTY: Doubles below 3NT show opening points.
b. THE 13+ HCP POWER JUMP: Opening a 1-level suit with 13+ pure HCP and an 8 to 11-card suit requires a normal opening at the 1-level, then use the jump 8 overcall on your second bid turn to show the massive length.
c. AFTER 1NT OPENING: Uses standard 4-Suit Transfers (2♣ Stayman, 2♦→♥, 2♥→♠, 2♠→♣, 2NT→♦).
d. AFTER 2♣ OPENING: Responder bids 2♦ to show weakness. The auction reverts strictly to standard SAYC rules on the second round.
e. FEATURE-ASK (AFTER WEAK 2): A 2NT response by partner asks for a feature in the weak hand. Opener rebids their original suit to deny outside values, or bids a new 3-level suit to show an outside Ace or a 3-to-4 card side fragment. Further, if the weak opener bids a second suit, it is deemed “feature” as well.
9. SLAM CONVENTIONS & INTERFERENCE DEFENSE
a. 4NT PURE ACE ASK: Asks strictly for Aces (does NOT include the trump King): - 5♣ = 0 or 4 Aces - 5♦ = 1 Ace - 5♥ = 2 Aces - 5♠ = 3 Aces
b. 5NT PURE KING ASK: Secondary inquiry asking strictly for Kings using the exact same step matrix shifted up (6♣=0/4, 6♦=1, 6♥=2, 6♠=3).
c. D0P1N2S3 DEFENSE (Under high-level interference over 4NT/5NT asks): - DOUBLE (D0): 0 Aces/Kings - PASS (P1): 1 Ace/King - NEXT SUIT (N2): 2 Aces/Kings (e.g., bidding 5♠ over an opponent's interference bid of 5♥) - SKIP (S3): 3 Aces/Kings (e.g., bidding 5NT over an opponent's interference bid of 5♥)
