Expected Value
The probability-weighted average of all possible outcomes of a decision.
Why it matters
Expected value reasoning is the foundation of probabilistic strategy in word games. Players who maximize expected value over many decisions outperform players who optimize single outcomes.
Examples
- A play scoring 24 with a strong leave may have higher EV than a play scoring 30 with a poor leave
Best practices
- Reason in long-run averages, not single-game outcomes
- Quantify when the decision is high-stakes
Frequently asked questions
Is expected value important for beginners?
expected value matters at every skill level, but beginners benefit most from understanding the basic concept rather than every edge case. Building a working mental model of expected value early prevents recurring mistakes in strategy.
How do I practice expected value effectively?
Practice expected value through deliberate isolation drills first, then through integrated play. Two short focused sessions per week will yield steady measurable gains within a month.
