MP 100bb Steal

Overview

MP 100bb Steal refers to a specific blind-stealing scenario in poker where a player in middle position (MP) opens with a raise holding a 100 big blind effective stack, aiming to collect the blinds and antes without a fight. This play is common in both cash games and tournaments, especially as stack depths become moderate and table dynamics tighten.

Context and Importance

Middle position (typically seats 3-5 at a 9-handed table) offers a balance – it is neither early nor late, so the stealing range must be wider than early position but narrower than late position. With 100 big blinds, the stack is deep enough to withstand re-raises and play postflop, but not so deep that opponents will automatically defend widely. The optimal steal frequency from MP depends on table tendencies, fold-to-steal percentages, and opponent skill.

Stealing Range and Adjustments

A common MP steal range at 100bb includes suited connectors (e.g., 65s–T9s), some offsuit broadways (AJo, KQo), pocket pairs (22–77), and decent suited aces (A2s–A9s). This range typically comprises about 15–20% of starting hands. However, adjustments are necessary based on:

• Blind opponents: Against tight defenders, widen the steal range; against aggressive 3-bettors, tighten and be prepared to fold or 4-bet.
• Antes: In tournaments with antes, the pot is larger, making steals more profitable; thus, the opening size can be smaller (e.g., 2.2–2.5bb) to risk less.
• Table image: A tight image allows more frequent stealing; a loose image invites more resistance.

Postflop Considerations

When the steal is called, the hand becomes a single-raised pot with position. With 100bb, the player has a favorable stack-to-pot ratio for continuation betting on flops that miss the opponent’s range. Common flop strategies include:

• Betting small (25–35% pot) on dry boards with high cards or draws.
• Checking back on wet, coordinated boards that hit calling ranges hard.
• Folding to check-raises without strong equity.

Risks and Counterstrategies

Frequent MP stealing can be exploited by observant opponents. Defenders may:

• 3-bet light from the blinds to punish wide ranges.
• Flat call with strong hands to trap or use position postflop.
• Lead out on flops to deny free cards.

To counter this, the stealer should balance by sometimes limping or raising with strong hands (QQ+, AK) from MP, and by occasionally 4-betting bluffs when facing a 3-bet.

Summary

MP 100bb Steal is a fundamental poker tactic that leverages position, stack depth, and table dynamics to accumulate chips without showdown. Mastery involves adjusting range and sizing based on opponent tendencies, stack size, and game format, while maintaining balance to avoid exploitation.
