High M: Play tight; avoid unnecessary risks.
Medium M: Be ultra-selective; only play the best hands.
Low M: All-in or fold; focus on doubling up.

4. Position Play

Early Position

High M: Play only premium hands.
Medium M: Be very selective; avoid marginal hands.
Low M: Play aggressively with any decent hand.

Middle Position

High M: Play a balanced range; mix up your play.
Medium M: Be selective; avoid speculative hands.
Low M: Play aggressively with any decent hand.

Late Position

High M: Play a wide range of hands; exploit position.
Medium M: Be selective; avoid marginal hands.
Low M: Play aggressively with any decent hand.

5. Post-Flop Play

Continuation Betting

High M: Use continuation bets to take down pots.
Medium M: Be selective with continuation bets; avoid giving away chips.
Low M: Use continuation bets sparingly; focus on value bets.

Check-Raising

High M: Use check-raising to trap opponents.
Medium M: Be selective with check-raising; avoid giving away chips.
Low M: Use check-raising sparingly; focus on survival.

Bluffing

High M: Use bluffs to take down pots.
Medium M: Be selective with bluffs; avoid giving away chips.
Low M: Use bluffs sparingly; focus on value bets.

6. Mental Game

Focus and Discipline

High M: Maintain focus; avoid distractions.
Medium M: Stay disciplined; avoid tilt.
Low M: Stay calm; avoid panic.

Adaptability

High M: Adapt to opponents’ playstyles.
Medium M: Adapt to changing dynamics.
Low M: Adapt to survival mode; focus on doubling up.

Patience

High M: Be patient; wait for good opportunities.
Medium M: Be patient; avoid unnecessary risks.
Low M: Be patient; wait for the right moment to double up.

By mastering these strategies, players can significantly improve their chances of winning at poker, whether in tournaments or cash games. Harrington’s methods provide a structured approach to the game, helping players navigate through various stages and situations with confidence.
