More flips can leave more replies
Violet to move. Compare immediate flips with the number of legal replies you leave the opponent. Which move leaves the fewest replies? Does the largest capture always do that here?
PRACTICE COLLECTION
Reversi — Decisions: compare what happens next
Four studies in future consequences. Distinguish a verified finish, a short tactical proof and a useful feature that does not establish a win.
Print these four studies with answers
Use a prediction, a test and a reason
- Read the task before opening the answer. Say where a move lands or what it changes.
- Test it on the playable board. In two-player studies, play both sides to inspect a reply.
- Undo and compare one alternative. Use the answer’s stated search limit when explaining the result.
- Repeat the decision on paper, where the move cannot be checked for you automatically.
These are teaching groups, not a player-tested difficulty ladder. The four board IDs match the technique examples, individual study pages and print pack.
Count choices as well as discs
Cream to move. Compare immediate flips with the number of legal replies you leave the opponent. Which move leaves the fewest replies? Does the largest capture always do that here?
No move means an automatic pass
Violet to move. Find a move that leaves the opponent unable to play. Does the mover get another turn, or do both players have no move and the game end?
The game can end with empty squares
Violet to move. Find a move that leaves the opponent unable to play. Does the mover get another turn, or do both players have no move and the game end?
Bring the idea to a fresh round
Capture legality, legal-move counts, corner stability, passes and final counts can be checked exactly. Mobility and avoiding access to an empty corner are strategic considerations, not universal winning rules. More legal moves, more current discs or ownership of a corner does not alone prove a final win. The regular game is local two-player play; example analysis is not an unannounced computer opponent or a claim of perfect strategy.
