The heart of American Mahjong strategy is **choosing the right hand** and **efficiently building toward it**. Let's learn how to make smart decisions.

## Step 1: Analyzing Your Starting Tiles

After the deal (and Charleston), you have 13 tiles. Look for:

### Pairs and Triples
- Multiple tiles of the same number
- Example: Three 7 Cracks = great foundation

### Sequential Tiles
- Consecutive numbers in the same suit
- Example: 4-5-6 Bams = potential run

### Jokers
- How many Jokers do you have?
- Jokers make complex hands achievable

### Flowers and Dragons/Winds
- Special tiles that appear in specific Card hands
- Don't discard these carelessly

## Step 2: Matching to Card Hands

Open your Card and scan for hands that match your tiles.

### Look for Multiple Matches

Don't commit to one hand immediately. Keep 2-3 options open early.

**Example starting hand:**
`1B 1B 2C 3D 4D 4D 5D FF FF G G W Joker`

Possible Card hands:
- **Consecutive Run** (you have 3-4-5 Dots started)
- **Like Numbers** (you have multiple 1s and 4s)
- **Flowers/Dragons** (two Flowers, two Green Dragons)

### Consider Point Values

Higher point hands are usually harder but more rewarding.

- **25-30 points**: Easier, good for beginners
- **40-50 points**: Moderate difficulty
- **75 points**: Complex, high risk/reward

**Beginner tip:** Start with 25-30 point hands until you're comfortable.

## Step 3: Using Jokers Wisely

Jokers are powerful but limited (only 8 in the set).

### When to Use Jokers

**Good uses:**
- Completing a tricky combination
- Substituting for rare tiles (like specific dragons)
- Filling in gaps in sequences

**Avoid:**
- Using Jokers for common tiles you're likely to draw
- "Wasting" Jokers on pairs (they can't be used for 2-tile sets anyway)

### Joker Strategy

If you have multiple Jokers, you can pursue harder hands that require specific combinations.

**Example:** A hand needing `DDDD RRRR 1111 2222` becomes much easier with 2-3 Jokers.

## Step 4: Charleston Strategy

The Charleston is your first strategic opportunity.

### What to Pass

✅ **Pass:**
- Tiles that don't fit any potential hand
- Tiles from suits you're not pursuing
- Excess tiles (if you have five 3s, pass some)

❌ **Don't Pass:**
- Jokers (almost never!)
- Tiles that fit multiple possible hands
- Flowers/Dragons unless you're certain you won't need them

### What to Hope For

During Charleston, hope to receive:
- Tiles that fit your 2-3 target hands
- Jokers (rare but valuable)
- Completing pairs into triples

## Step 5: Mid-Game Decisions

As the game progresses, you'll need to **commit** to one hand.

### When to Commit

Commit when:
- You have 70%+ of one hand completed
- Your other options look less viable
- You draw a key tile for one specific hand

### Pivoting Between Hands

Sometimes your initial plan doesn't work out.

**Red flag signs:**
- You're not drawing tiles you need
- Opponents are discarding tiles that suggest they're pursuing similar hands
- You're 10+ turns in with no progress

**When to pivot:**
- Early game (turns 1-8): Easy to switch
- Mid-game (turns 9-15): Possible but risky
- Late game (turns 16+): Usually too late

## Step 6: Defensive Play

Unlike Riichi, American Mahjong is less focused on defense, but you should still pay attention.

### Reading Opponents

Watch what tiles opponents:
- **Call and expose** - This reveals part of their hand
- **Discard** - They likely don't need these suits/numbers
- **Don't discard** - They might be saving these

### Safe Discards

If you're unsure what to discard:
- Discard tiles others have already discarded (less likely to be needed)
- Discard from suits no one is pursuing
- Keep Jokers and versatile tiles

## Common Beginner Hand Patterns

Here are beginner-friendly hands to look for:

### 1. Simple Consecutive Run
`1111 2222 3333 FF`
- Four 1s, four 2s, four 3s (all same suit), two Flowers
- Easy to spot and build

### 2. Wind Hands
`NNNN EEEE SSSS WW`
- Four of each wind, pair of winds
- Rare tiles but clearly defined

### 3. Dragon Hands
`DDDD GGGG RRRR FF`
- Four of each dragon, two Flowers
- Simple structure

### 4. Like Numbers
`1111 1111 1111 11`
- All 1s in different suits
- Easy to track

## Building Efficiency Tips

### Tile Counting

Keep rough track of tiles:
- How many 5 Dots have been discarded?
- Are there still Jokers available in the wall?
- Has anyone exposed dragons?

**Rule of thumb:** If 3+ of a tile you need have been discarded, consider pivoting.

### Rack Organization

Organize your rack by:
- Exposed tiles on one end
- Working tiles in groups by combination
- Discard candidates on the other end

Clear organization helps you spot opportunities quickly.

### Speed of Play

American Mahjong is social, but don't slowplay:
- Have your next 2-3 discards mentally planned
- Call tiles decisively
- Respect the table pace

## Example Hand Building

Let's walk through a hand:

**Starting tiles:** `2B 2B 3D 5D 5D 5D 7C 8C 9C FF G G S Joker`

**Analysis:**
- Three 5 Dots - strong foundation
- 7-8-9 Cracks - consecutive run potential
- Two Flowers, two Green Dragons
- One Joker

**Card options:**
1. Consecutive hand with 5s, 6s, 7s (use Joker for 6D)
2. Hand with Flowers and Dragons
3. Hand with Like Numbers (multiple 5s)

**Charleston:** Pass the 2 Bams and South wind (don't fit patterns).

**Mid-game:** You draw another 5 Dot. Now you have four 5 Dots - commit to a hand needing 5555.

**Finishing:** Look for a Card hand like `5555 6666 7777 FF` and work toward those 6s and 7s.

## Key Takeaways

- **Analyze** starting tiles for patterns
- **Keep 2-3 options** open early
- **Use Jokers** for difficult combinations
- **Commit** once you have 70% of a hand
- **Watch** what opponents call and discard
- **Practice** with simpler 25-30 point hands
