Contract Bridge (or simply "Bridge") is a trick-taking card game played by four players in two partnerships. It's one of the most intellectually challenging and socially engaging card games in the world.
Bridge in 60 seconds:
Four players, two teams (North-South vs East-West)
Players bid to declare how many tricks they can win
One team tries to make their contract, the other tries to stop them
Points are scored based on success or failure
Why Play Bridge?
Mental Challenge: Strategy, memory, and logic combined
Social Game: Play with friends or meet new people
Lifelong Learning: Always something new to discover
Global Community: Played by millions worldwide
Competitive & Casual: From kitchen tables to world championships
🎴 The Basics
The Deck
Bridge uses a standard 52-card deck with four suits:
♠ Spades (Black)
♥ Hearts (Red)
♦ Diamonds (Red)
♣ Clubs (Black)
Each suit has 13 cards: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2
The Players
Four players sit in a square:
North
Partner of South
West
Partner of East
East
Partner of West
South
Partner of North
💡 Key Point: North-South are partners against East-West. Partners sit across from each other and work together to win.
The Deal
Each player receives 13 cards. Players can see only their own cards (not their partner's or opponents' cards).
🔢 Counting Points (HCP)
Before bidding, you count your High Card Points (HCP). This tells you how strong your hand is:
💡 Important: The deck has exactly 40 HCP total (4 Aces × 4 = 16, plus Kings, Queens, Jacks). Average hand = 10 HCP.
⚡ Two Phases of Bridge
Every hand of bridge has two distinct phases:
Phase 1: The Auction (Bidding)
Players take turns bidding - stating how many tricks they think their partnership can win. The bidding determines:
How many tricks the declaring side must win (7-13 tricks)
What suit is trump (or if playing No Trump)
Who is declarer (the person who plays the hand)
🎯 This trainer focuses on Phase 1! We're teaching you the auction (bidding) because it's the foundation. Card play comes in Phase 2.
How Bidding Works
Bids go in order: North → East → South → West → North... until three players Pass in a row.
A bid consists of:
A level (1-7) = tricks above 6 you'll try to win
A denomination (♣, ♦, ♥, ♠, or NT)
Example Bids:
• "1♠" = "We'll win 7 tricks (6+1) with spades as trump"
• "3NT" = "We'll win 9 tricks (6+3) with no trump suit"
• "Pass" = "I don't want to bid right now"
⚠️ Bidding Rule: Each new bid must be higher than the last. You can't bid "1♠" after someone bid "2♣" - you'd need to bid "2♠" or higher.
Phase 2: The Play (Not in this trainer)
After bidding ends, the cards are played. One player (the declarer) tries to win the number of tricks they bid, while opponents try to stop them.

🎯 Key Bidding Concepts
Trump vs. No Trump
Trump: One suit becomes "boss" - trump cards beat all other suits. No Trump (NT): No boss suit - highest card in the suit led wins.
Opening Requirements
To open the bidding (make the first bid), you typically need:
13+ HCP for most opening bids
12-14 HCP for 1NT opening (weak no trump)
15-17 HCP for 1NT opening (strong no trump)
6-11 HCP for weak two bids (2♥, 2♠) with a long suit
💡 ACOL Note: In ACOL, opening 1 of a major (1♥ or 1♠) only promises 4+ cards, not 5. This is a key difference from Standard American.
Responding to Partner
When partner opens, you respond based on:
Your HCP
Whether you have support (cards in partner's suit)
Your distribution (how cards are divided among suits)

🔧 Basic Conventions You'll Learn
Bridge has many conventions - artificial bids with special meanings that partners agree on. Here are some you'll practice:
Stayman
After partner opens 1NT, bid 2♣ to ask "Do you have a 4-card major?"
Jacoby Transfer
After partner opens 1NT, bid 2♦ to show 5+ hearts, or 2♥ to show 5+ spades.
Takeout Double
After opponent opens, double to show opening strength and support for unbid suits.
