Two-Move Lookahead

Definition

Two-move lookahead means choosing your current guess partly by how well it sets up your next guess across likely outcomes, rather than evaluating moves one at a time.

Why it matters

Looking ahead avoids guesses that look strong now but leave you stranded next move, and is a hallmark of expert planning.

Examples

  • Picking a guess whose every result has a clear follow-up.
  • Avoiding a guess that could leave many indistinguishable candidates.

Best practices

  • Anticipate the main results and your reply to each.
  • Prefer guesses with good follow-ups in all branches.

Frequently asked
