Blind stealing — hay đơn giản là "steal" — là hành động raise từ late position để win blinds mà không cần showdown. Đây là một trong những nguồn EV quan trọng nhất trong poker, đặc biệt ở SB và BB games. Player không steal đủ bỏ phí hàng chục BB mỗi 100 tay.
Tại Sao Blind Stealing Profitable?
Dead Money Equation
Mỗi orbit (vòng), SB post 0.5BB và BB post 1BB → 1.5BB dead money trong pot.
Nếu bạn steal từ BTN:
- Raise 2.5BB
- Win SB + BB (fold) = win 1.5BB dead money
- Risk 2.5BB to win 1.5BB
Nhưng: Fold equity từ blinds thường 55–70% → steal profitable ngay cả với weak hands.
EV Calculation (Đơn Giản)
Steal 2.5BB, both blinds fold 60% tổng cộng:
EV = 0.6 × 1.5BB - 0.4 × (post-flop EV when called)
Post-flop EV khi called từ BTN (có position) = thường neutral or positive.
Kết quả: Steal profitable even with borderline hands.
Vị Trí Steal Và Ranges Tương Ứng
CO (Cutoff) Steal
Khi fold đến CO, UTG/MP/HJ đã fold → chỉ còn BTN, SB, BB.
Appropriate CO steal range: ~25–30%
Tay bài good để steal từ CO:
- Suited aces (A2s+)
- Suited connectors (89s, T9s, JTs, QJs)
- Broadway combinations (KQo, KJo, QJo)
- Small pairs (22+)
Why not steal super wide? BTN still has position if they call.
BTN (Button) Steal — Most Profitable Position
BTN là vị trí steal good nhất vì:
- Chỉ SB và BB còn lại
- Nếu called, bạn có position on both
BTN steal range: ~40–50%
Bao gồm hầu hết suited hands, broadways, pairs — chỉ fold weakest offsuit trash.
Specific BTN steal hands:
- All pairs (22+)
- A2s+ (all suited aces)
- K7s+, Q8s+, J9s+ (suited face cards)
- T9s, 98s, 87s, 76s (suited connectors)
- ATo+, KTo+, QJo (offsuit broadways)
- Many others depending on opponent tendencies
SB Steal (Blind vs. Blind)
SB vs. BB steal — only BB left:
- SB raise into only 1 player
- But OOP post-flop
SB steal range: ~40–55% (wider than CO but tighter on pure garbage)
SB steal sizing usually larger (3x vs. 2.5x) to compensate for OOP disadvantage.
Steal Sizing
Standard Steal Sizes
| Position | Recommended Size |
|---|---|
| CO | 2.5–3x BB |
| BTN | 2.5x BB |
| SB | 3x BB |
Why SB larger? OOP post-flop → charge BB more to call.
Why BTN smaller? IP post-flop → risk less, still get folds.
Adjusting Steal Size To Opponents
vs. Tight blinds (fold > 65%): Can steal with minimum raise (2x BB) — they fold anyway.
vs. Loose defenders (fold < 40%): Increase size slightly (3x) — make it more expensive to defend with speculative hands.
vs. 3-bet happy players: May reduce steal frequency or adjust by position.
Tay Bài Good Nhất Để Steal
Steal hands nên có một trong hai tính chất:
1. Good Blockers
Hands block SB/BB calling/3-bet ranges:
- Ax hands: Block AA, AK, AQ in their range
- Kx hands: Block KK, KQ combos
2. Good Post-Flop Equity
When called, these hands perform reasonably:
- Suited connectors: Flush draws, straight draws
- Suited aces: Flush draws + top pair potential
- Broadway hands: TPTK when they connect
Steal But Don't Over-Value Post-Flop
Stealing with 72o is profitable vs. fold-happy blinds, but when called, you're in tough spots. Stealing with T9s — even if called — you have playable equity.
Balance: Mix pure steal hands with equity hands in steal range.
Defending Blinds Against Steals
The other side: How to defend when someone steals.
Minimum Defense Frequency (MDF)
To prevent profitable steals, you must defend enough:
MDF = Pot / (Pot + Steal Size)
Steal 2.5BB into 1.5BB pot (blinds): MDF = 1.5 / (1.5 + 2.5) = 37.5%
So BB must defend ~38% of hands minimum.
In reality, BB defends ~50%+ in good range construction.
BB Defense Range
BB has great pot odds (1BB to call 1.5 more) → wide defense range:
Defend: Any pair, Ax, suited connectors, suited broadways Fold: Very weak offsuit combinations (72o, 83o, 94o)
SB Defense
SB more difficult (OOP vs. BTN steal):
- Can 3-bet: Premium hands + bluffs (polarized)
- Can call: Medium hands with implied odds (IP after call... wait, SB is OOP vs. BTN always)
- Often better to 3-bet or fold than flat call OOP
SB vs. BTN steal: 3-bet range or fold more aggressively than BB.
Re-Steal (3-Bet Steal)
Re-steal = 3-bet từ blinds vs. steal raiser.
When profitable:
- Steal raiser has wide range (often weak)
- You have reads that they fold to 3-bets
- You have strong hand + dead money
Re-steal sizing: 3x–4x steal size (OOP, need to charge more)
Example: BTN steal 2.5BB, BB re-steal to 10BB.
Re-steal hands: Premium value + bluffs (A5s, K5s — blockers + some equity if called).
Steal Adjustment Theo Table Dynamics
vs. Tight Table
Steal very wide — everyone folding → dead money accumulates.
Steal frequency: Max (50%+ from BTN)
vs. Aggro Table
Blinds 3-bet frequently → reduce steal frequency, only steal with hands you're comfortable 4-betting or calling 3-bet.
vs. One Tight, One Loose Blind
Tight SB, Loose BB: Steal targeting BB — they call too much → value bet more post-flop. Loose SB, Tight BB: SB enters pot often (limp/raise) → be ready for SB action.
Tracking Individual Blind Defense
If HUD available, check:
- Fold to steal (CO/BTN/SB separately): High > 65% = steal more
- 3-bet vs. steal: High = tighten steal range or 4-bet more
Sai Lầm Blind Stealing
1. Never Stealing
"I only raise with good hands" → Blinds accumulate profit over time: 1.5BB × many orbits = significant.
Fix: Steal from BTN/CO with standard late-position range.
2. Always Stealing Regardless
100% steal regardless of table: Easy to exploit.
Fix: Adjust based on blind defense tendencies.
3. Wrong Post-Flop Plan
Steal, get called, then check-fold every flop → gives up fold equity earned preflop.
Fix: Have plan for most board textures when steal gets called. C-bet selectively.
4. Ignoring Stack Depth
Short stack BB (10BB) calling your steal = committed → they're going all-in anyway. Adjust steal range.
Deep stack BB → more post-flop play → range can be wider (more implied odds hands).
Kết Luận
Blind stealing là một trong những highest-frequency profit centers trong poker. Every orbit, there's 1.5BB on the table — player who consistently claims that dead money makes significant extra profit. Master steal timing, sizing, and range selection, then adapt to how opponents defend. Combined with solid post-flop play when called, stealing becomes reliable income stream every session.
