⚖️ IP vs OOP — The Core Difference
IP (In Position) Advantages
- Act after seeing opponent's action
- Easier to take free cards
- Better pot size control
- Higher bluff success rate
- Higher showdown value
OOP (Out of Position) Disadvantages
- Must act first with no information
- Choose bet/check without knowing opponent's intent
- Easier to give free cards
- Bluffs are less effective
- Pot tends to grow larger
EV Difference Estimate
The same AJo played from BTN vs UTG has a large long-term EV difference. Research suggests positional advantage creates a 2-4BB per 100 hands gap.
🪑 Each Position's Characteristics and Strategy
EP (Early Position) / UTG
Rec. VPIP
12-15%
Strength
Range Strength
Weakness
All OOP
- Most players act behind → play tight
- Entering signals a "strong range" to all opponents
- Often OOP vs everyone postflop (except BB)
- Exploit: Widen slightly vs passive tables. Tighten further vs aggressive tables
MP (Middle Position)
Rec. VPIP
18-22%
Behind
CO/BTN/SB/BB
- Slightly wider than EP. Add 88, KQ-type hands
- Be aware CO/BTN have position on you
- Suited connectors start gaining value (risk of being squeezed from behind)
- Exploit: Widen if BTN is a nit. Tighten if BTN is a LAG
CO (Cutoff)
Rec. VPIP
26-30%
Strength
Wide Range
- One seat before BTN. Battle for BTN position matters
- Note: calling BTN means being OOP postflop
- Open with 55+, A8s+, wide suited hands
- Exploit: Widen steal range if BTN folds often
★ BTN (Button) — Best Position
Rec. VPIP
44-55%
Postflop
Always IP
- Always IP postflop (only SB/BB act before)
- Very wide open range is effective — enter ~50% of hands
- Adjust range dynamically based on SB/BB tendencies
- Exploit: Very wide vs nit BB. Tighten and value-bet vs calling station BB
- ISO raises are most effective from BTN
SB (Small Blind)
Rec. VPIP
35-40%
Weakness
Always OOP
- Always OOP postflop (worst position overall)
- No limping in principle — raise or fold
- Only heads-up with BB → adapt to BB's style
- Exploit: Aggressive steals vs tight/nit BB. Tighten and value-bet vs loose BB
- SB 3-bets should be value-heavy against IP opponents
BB (Big Blind)
Defense
Wide
Discount
Yes
- Already invested BB → "discounted call" is available
- Defend wide vs BTN opens (~35-40%)
- Always OOP postflop — use check-raise or donk bet with strong hands
- Exploit: Defend wider vs BTN non-nit. Tighten vs nit BTN
- Actively look for squeeze spots (BTN open + MP call, etc.)
