[EV Retrospective] How to use EV to check for errors?

The core conclusion of the Poker EV Review: What really matters is the decision, not the result.

Many beginners, when reviewing their games, only look at whether they won or lost.

But true experts will see: Is this decision a positive EV (Electronic Performance) decision?

A truly advanced review is an EV (Effective Value) analysis.

What is EV Review?

EV Review Representative: Using Expected Value to Examine Decision Quality

include:
→ Is the call correct?
→ Is Bluff reasonable?
→ Does Raise have Fold Equity?

What true experts analyze is long-term profitability.

Why can't the result represent right or wrong?

Because of the existence of VarianceEven if: Negative EV Call catch-up

It is still possible that this was a wrong decision.

A correct result does not necessarily mean a correct strategy.

The first step in the post-mortem analysis: Rebuild the Range

The first thing a true master does is not to look at themselves.Instead, we should consider: What might our opponent be like?

include:
→ Value Range
→ Bluff Range
→ Draw Range

Range analysis is the core of EV review.

Step 2: Recalculate Equity

Experts will re-analyze: What was the winning probability at that time?

include:
→ Are the Outs correct?
→ Are Dirty Outs deducted?
→ Is the strength of the hand overestimated?

Many errors actually stem from Equity misjudgments.

Step 3: Analyze Pot Odds

Experts will recalculate: Are Pot Odds enough?

If: the win rate is lower than the requirement

Many calls may actually be negative EV.

Pot Odds are an important checkpoint for post-mortem analysis.

Step 4: Analyze Fold Equity

If we had chosen Raise then, how much would our opponents have folded?

If the fold rate is insufficient, Bluff may result in negative EV.

A truly advanced post-game analysis involves not only looking at the calls, but also at the offensive EV (Effective Value).

Classic EV Retrospective Case

However, upon review, it was found that:
→ Insufficient Pot Odds
→ The opponent may have an even higher flush.
