Node Lock

What is a Node Lock?

Node Lock, in Chinese it is calledNode locking,It meansIn a specific node of the Solver, manually modify the opponent's strategy and then recalculate the optimal response.

Node Lock can simulate real players, not perfect players.

What can be modified in a Node Lock?

For example：
→ Bluff Frequency
→ Fold Frequency
→ Check Frequency
→ Bet Size
→ Raise Frequency
→ Call Frequency

Different player preferences can be set at any decision point.

Why is Node Lock needed?

This is because:
→ Real players rarely use GTO
→ Can simulate entertainment players
→ Can simulate professional gamers
→ Can create the best exploit

Node Lock allows the Solver to more closely resemble a real hand.

The relationship between Node Lock and Exploit

For example：
→ Opponent Over Bluff
→ Opponent Under Bluff
→ Opponent Over Fold
→ The opponent is too passive

Through Node Lock, the Solver can recalculate the most profitable exploit strategy.

Node Lock is one of the most important tools for exploring exploits.

Differences between Node Lock and GTO

GTO:Assuming both sides adopt the optimal strategy

Node Lock:Assuming one side deviates from GTO, then a new optimal countermeasure will be sought.

Node Lock does not overturn GTO, but rather studies exploits based on GTO.

Practical Examples

RiverYou observed that your opponent almost never bluffs.Therefore, Node Lock was used to reduce the opponent's River Bluff Frequency. After the Solver recalculated, it was suggested that you increase the Fold Frequency and reduce Hero Calls.

Node Lock can transform real-world information into optimal decision-making.

Common Misconceptions for Beginners

Many players believe Node Lock is simply messing with the Solver.In fact,Node Lock must be based on real data, match records, and player preferences. If configured incorrectly, the resulting exploit strategy may be completely flawed.

The value of Node Lock comes from accurate information, not subjective guesswork.

Key conclusions

Node Lock is the most important advanced feature of modern Texas Hold'em solvers and an indispensable tool for researching exploit strategies.

Understanding Node Lock, Node, Solver, Game Tree, GTO, Exploit, Range, Bluff Frequency, Fold Frequency, and EV thinking will help you simulate the behavior patterns of real players, build a more realistic and profitable decision-making system, and truly achieve a balance between theory and practice.
