## Decision-by-Decision

### Hand #53 (3bef78d4) — J9o BTN, SB raises to $3K → Fold ✓
Standard fold. J9o facing a 3x raise from SB with 6 active players on BTN.

### Hand #54 (b255fdff) — Q3o BTN, raise to $2K → Fold ✓
Trash hand, easy fold.

### Hand #55 (3c80ef89) — Q3o BTN, limp (to_call=$1K) → Fold ✓
Q3o multi-way, conservative but fine. No equity to justify a BTN raise with callers behind.

### Hand #56 (1ff1dc3c) — K6o BTN, limp (to_call=$1K) → Fold ✓
K6o is trash, correct fold.

### Hand #57 (b7305972) — QJs UTG (#3/5), limp (to_call=$500) → Fold ⚠️
**Too tight.** QJs from UTG in a 5-handed game should at minimum call $500 (0.5 BB), arguably raise. This is the same Gen1 `g1_big_stack_preflop` over-tightness seen in previous audits.

**Data issue**: BB posting event not captured — `sb=6 bb=6` (both blinds on same seat), `pot=500 cur_bet=500` instead of `pot=1500 cur_bet=1000`. The BB was never sent as a player_action event.

### Hand #58 (03ce2752) — ATo BB, checked around → Check/Check/Check/Fold ✓
- Preflop check: ✓ (BB option, limped pot)
- Flop check (4s Kc 9s): ✓ (missed completely, A-high)
- Turn check (6s): ✓ (still nothing)
- Turn fold facing $2K bet: ✓ (ATo, no pair, two players betting/calling)

**Data issue**: `pot=0 cur_bet=0` throughout preflop and flop — same `sb=bb=6` bug. Pot should be $2000+ from blinds + limp. Not harmful for the fold decision but degrades bet-sizing quality.

### Hand #59 (1921235) — T7o SB, raise to $4.5K → Fold ✓
T7o facing a 4.5x raise with 5 active players. Clear fold.

**Data issue**: Message reconstruction fired mid-hand — game_start was sent twice (19:26:35 and 19:26:41), resetting hero's SB completion ($1000 call) back to just SB ($500). The bot's wager tracking was wrong ($500 instead of $1000), but the fold is correct regardless.

## Summary

| # | Hand | Cards | Position | Decision | Rating |
|---|------|-------|----------|----------|--------|
| 53 | 3bef78d4 | J9o | BTN | Fold vs 3x raise | ✓ Correct |
| 54 | b255fdff | Q3o | BTN | Fold vs raise | ✓ Correct |
| 55 | 3c80ef89 | Q3o | BTN | Fold vs limp | ✓ Correct |
| 56 | 1ff1dc3c | K6o | BTN | Fold vs limp | ✓ Correct |
| 57 | b7305972 | QJs | UTG | Fold vs limp | ⚠️ Too tight |
| 58 | 03ce2752 | ATo | BB | Check/Fold | ✓ Correct |
| 59 | 1921235 | T7o | SB | Fold vs 4.5x raise | ✓ Correct |

**Strategy**: 6/7 correct. Hero is card-dead (J9o, Q3o, Q3o, K6o, QJs, ATo, T7o). The QJs fold from UTG is the only notable strategy issue — same Gen1 over-tightness pattern.

**Data quality issues** (3 types):
1. **Missing BB posting event** (Hands #57, #58): BB action not captured by userscript → `sb=bb=6`, `pot=0`. The `game_start` has correct `sb=500 bb=1000` but the BB player_action never arrives.
2. **Reconstruction reset** (Hand #59): Observer re-attached mid-hand, replaying game_start and resetting wager tracking. Hero's SB completion was lost.
3. **All blinds parsing correct** at $500/$1000 — no corrupt-zero issue.

**Net result**: Hero stack $200K → $197.5K (lost $2.5K to blinds over 8 minutes, no hands played postflop).
