MP Position Standard Opening Strategy: From Range Construction to Practical Application

Context: STRATEGY article: mp-position-opening-strategy

What is MP?

MP (Middle Position) is the poker position located after UTG (Under the Gun) and before Hijack (HJ). In a 6-max table, MP usually refers to the second position to act (after UTG); in a 9-max table, MP includes MP1 and MP2. The MP position is in the middle ground: it has more information than UTG (knowing UTG's action), but there are still positions to act behind (CO, BTN, etc.), so opening needs to be cautious.

Standard MP Opening Raise Range

Below is a standard opening range for MP suitable for most 6-max or 9-max tables (assuming effective stack of 100 BB, no ante or small ante). This range is based on GTO principles, balancing value and bluffs.

Raise Range (Approximately 15%-18% of hands)

• Strong hands (value raises):

  • All pairs: 22+ (but 22-66 are usually calls or folds depending on table dynamics; simplified here)
  • All suited aces: A2s+ (A2s-A5s can be considered semi-bluffs)
  • All offsuit aces: ATo+
  • All suited kings: K9s+
  • All offsuit kings: KJo+
  • All suited queens: Q9s+
  • All offsuit queens: QJo (sometimes folded depending on opponents)
  • All suited jacks: J9s+
  • All suited tens: T9s
  • Suited connectors: 98s, 87s, 76s (as semi-bluffs)

• Hands to fold:

  • Small offsuit suited connectors (e.g., 65o, 54o)
  • Weak offsuit aces (A9o and below)
  • Weak offsuit kings (KTo and below)
  • Weak offsuit queens (QTo and below)
  • Offsuit gappers (JTo, T9o can sometimes be raised, but usually folded)

Adjustment Factors

• Opponent type: If the blinds are tight-passive, you can widen your range; if they are aggressive, tighten your range and increase 4-bet bluffs.
• Stack depth: With deep stacks (>150 BB), increase the raise frequency of suited connectors and gappers; with short stacks (<40 BB), mainly raise strong hands and reduce bluffs.
• Antes: When there are antes, there is more dead money in the pot, so widen your opening range, especially by adding small pairs and suited connectors.

Post-Flop Strategy Key Points

Continuation Betting on the Flop (C-bet)

• Dry flops (e.g., K-7-2 rainbow): C-bet with top pair or better value hands and draws, frequency around 70%-80%.
• Wet flops (e.g., T-9-6 suited): Reduce C-bet frequency to about 50%, bet mostly with strong hands and strong draws, check weak hands.
• Range advantage: If the flop favors your range (e.g., your raising range contains many high cards and the flop has an A or K), increase your C-bet frequency.

Turn and River

• Turn: Adjust based on whether the turn improves your range or your opponent's range. If the turn is a blank, continue betting for value; if it completes a straight or flush, proceed with caution.
• River: Make thin value bets and bluff sparingly. Usually only bluff when you have a clear range advantage or your opponent has a high fold rate.

Common Mistakes

1. Overly wide raising range: MP is not CO or BTN; you cannot raise as frequently as late positions. Avoid raising weak hands like KTo, QJo unless you have a specific read.
2. Ignoring positional disadvantage: MP lacks positional advantage post-flop, so pre-flop you should lean towards raising strong hands rather than speculative hands.
3. Too high C-bet frequency: On wet flops, MP's range advantage is not obvious; excessive C-betting can be exploited by opponents' check-raises.

Practical Examples

Example 1: 6-max, effective stacks 100 BB. You are in MP with A♠K♠. UTG folds, you raise to 3 BB, CO and BTN fold, SB calls, BB folds. Flop: K♦9♠4♣. You C-bet 4 BB, SB folds.

Example 2: 9-max, effective stacks 120 BB. You are in MP1 with 7♠6♠. UTG folds, you raise to 3 BB, MP2 folds, CO calls, BTN, SB, BB fold. Flop: J♠8♠2♣. You C-bet 4 BB (semi-bluff), CO folds.

Summary

The core of MP opening strategy is balance: you need to leverage positional advantage to extract value while avoiding being exploited by later positions due to an overly wide range. Remember, your MP raising range should be slightly wider than UTG's but tighter than CO and BTN. By continuously adjusting your range based on opponents and stack depth, you can build a consistent profit from MP.
