SB VPIP

Overview

SB VPIP (Small Blind Voluntarily Put In Pot) is a poker statistic that measures how often a player voluntarily invests chips from the small blind position, excluding forced bets like the blind itself. It is expressed as a percentage of all hands dealt in that position. This stat is commonly used in online poker tracking software like PokerTracker or Hold'em Manager to analyze a player's tendencies.

Interpretation

A high SB VPIP indicates a player who plays many hands from the small blind, often calling raises or open-limping. A low SB VPIP suggests a tight player who only enters pots with strong holdings. Typical ranges for solid regulars are:

• Tight: 10-20%
• Average: 20-30%
• Loose: 30%+

However, SB is a disadvantageous position because the player acts first post-flop and has already invested half a big blind. Therefore, even loose players often have a lower VPIP from SB compared to button or cutoff.

Strategic Implications

Open-raising

From SB, open-raising is usually recommended only with strong hands (e.g., top 15-20% of hands) because of positional disadvantage. A high SB VPIP from open-raises can indicate a player who overplays marginal hands out of position.

Calling raises

Calling a raise from SB is often discouraged, as the player will be out of position and the pot is already inflated. A high SB VPIP from calling raises may suggest a player who defends too wide, which can be exploited.

Limping

Some players limp from SB to see cheap flops, but this is generally considered weak because it invites the big blind to check or raise, and the small blind remains out of position. A high limp-based SB VPIP is often a sign of a passive or recreational player.

Comparing to Other Positions

• Button VPIP: Typically highest, as position is best. Button VPIP often 30-50% for aggressive players.
• Cutoff VPIP: Slightly lower than button, still higher than blinds.
• UTG VPIP: Lowest, often under 20% for tight ranges.

SB VPIP should be lower than these positions due to positional disadvantage. A player with SB VPIP close to their button VPIP is likely too loose from the blinds.

Adjustments

• vs. a high SB VPIP player: They play many hands out of position; exploit by raising more when they limp, and value bet thinner post-flop.
• vs. a low SB VPIP player: They fold often; steal more from button or cutoff, and avoid bluffing them when they do enter.

Example

A player with SB VPIP of 25% and a big blind VPIP of 30% is moderately loose from the blinds. In contrast, a player with SB VPIP of 10% and BB VPIP of 15% is very tight, likely folding most weak hands.

Limitations

SB VPIP alone does not distinguish between open-raising, calling, or limping. Combined with stats like SB Open Raise, SB Call, and SB Fold, it gives a fuller picture. Also, sample size matters; stats from fewer than 100 hands can be misleading.
