Node Locking

In a poker game tree, each decision point is called a "node," and "node locking" is a process where the solver fixes or locks certain decisions or actions at specific nodes while computing strategies. It means that the solver assumes a particular decision or action at a certain node and then calculates the optimal strategies for the remaining parts of the game tree based on that assumption.

Node locking can be used to explore specific scenarios or study the impact of certain actions on the overall strategy. By fixing decisions at specific nodes, players or analysts can gain insights into how different choices or actions affect the outcome of the game and the recommended strategies. It allows for a deeper analysis of complex poker situations and helps players refine their decision-making processes.
