|---|---|---|---|---|
| Easy | Learning forced jumps and king promotion | 1 move ahead (its own; never your reply) | Never checks your reply, so it often leaves a man you can jump | Open from the center and set up simple two-for-one jumps |
| Medium | Regular play and steady improvement | 3 moves ahead; follows jump sequences to the end | Spots obvious one-move blunders; shorter endgame plans | Trade when ahead; keep the back rank intact longer |
| Hard (this page) | Players who want more calculation | 5 moves ahead; follows jump sequences to the end | Stops at five moves ahead, so it is not master strength | Work through forced jump lines before you touch a piece |
