Node Lock refers to manually modifying the strategy of a specific node during Solver analysis, causing the opponent to make decisions based on a specified playstyle instead of GTO, and then recalculating the optimal response strategy.

Since real players rarely play exactly according to the GTO, professional players often use Node Lock to simulate opponents' over-bluffing, under-bluffing, over-folding, or calling station behaviors to identify the most profitable exploit strategies.

This article will provide a complete introduction to the definition, operation, Solver application, and practical analysis of Node Lock.

A node is a decision point in the Texas Hold'em game tree. A new node is formed whenever a player needs to make an action (Check, Bet, Call, Raise, or Fold).

In the Solver, the entire game is broken down into countless Nodes, each representing a specific situation. The Solver calculates the Game-Oriented Strategy (GTO) for each Node. Understanding Nodes is a crucial foundation for learning Solver, Node Lock, Game Tree, and GTO.

This article will provide a complete introduction to the definition of Node, Game Tree, Solver, and practical applications.

MDF is an abbreviation for Minimum Defense Frequency, and it is one of the most important defensive concepts in Texas Hold'em GTO (Game Theory Optimization).

MDF (Mean Defense Principle) is used to calculate the theoretical minimum percentage of hands a player needs to defend against an opponent's bet to prevent them from profiting through overbluffing. While MDF provides a theoretical baseline for defense percentages, in practice, it's essential to combine it with hand strength, blocker, pot odds, solver analysis, and opponent habits to make the best decision.

This article will provide a complete introduction to the meaning, formula, relationship with GTO, and practical applications of MDF.
