Blind vs Blind Mastery: Winning the Most Frequent Battle

Why BvB Is So Important

When action folds to the small blind, it creates a blind vs blind situation — the most frequently contested pot at a 6-max table. How you handle BvB has a major impact on your overall win rate.

Small Blind Strategy

Opening Range

From the SB, you should play ~55-65% of hands (when it folds to you). This is much wider than any other position because:

• Only one opponent to get through
• Dead money from the BB to steal
• Your OR immediately makes you a 60/40 favorite to win the pot

Raise vs Limp

There are two schools of thought:

Pure raise strategy (recommended for simplicity): Open raise to 2.5-3x with your entire playing range. This simplifies decisions.

Mixed strategy (GTO-optimal):

• Raise the top ~40% of your range
• Limp the next ~20-25%
• Fold the rest

Limping is valid because you only face one opponent and already have half a BB invested.

3-Bet from SB vs BB limp

If you open and BB 3-bets, you face the toughest OOP spot. Prepare a 4-bet/fold range and minimize flat calls.

Big Blind Strategy

Defending vs SB Open

Since the SB opens very wide, you should defend very aggressively:

• 3-Bet: 20-25% of hands
• Call: 30-40% of hands
• Fold: Only the worst 35-40%

3-Bet Range from BB (vs SB)

Value: 88+, ATs+, AJo+, KQs Bluffs: A5s-A2s, K9s-K7s, suited connectors, suited gappers

Calling Range from BB

Medium pairs (77-55), suited broadways, connectors, and hands that play well postflop.

BvB Postflop Dynamics

Wider Ranges = Different Board Textures

Since both players have wide ranges, boards interact differently:

• Low, connected boards (7♠ 6♥ 4♦) — Both players hit these boards hard
• Ace-high boards — SB as raiser has more Ax combos
• King-high dry boards — Both players have similar ranges

c-Betting in BvB

• SB (as raiser): C-bet less frequently than normal (50-55%). BB's wide defense range connects with many boards.
• BB (after calling): Lead (donk bet) is more viable because your range includes many strong hands that hit boards the raiser doesn't expect.

Common BvB Mistakes

1. SB folding too much — Fold equity vs one player should motivate wider opens
2. BB folding to SB too much — SB is opening wide; you must defend
3. Ignoring limps from SB — A limped SB range is different from a raised range
4. Not adjusting c-bet frequency — Standard 6-max c-bet ranges don't apply in BvB

💡 Mastering BvB battles can add 2-3 bb/100 to your overall win rate.
