When you get well into the cave you will encounter some nasty dwarves. The first one simply tosses an axe at you and runs away. The axe misses. Get the axe; you'll need it when you see the dwarves again. On your second encounter with the dwarves, you'll see one or more, who will throw knives at you. The first salvo always misses. Toss the axe at a dwarf, fetch it again, and keep tossing until you have killed all the dwarves present. You'll need to do this each time a dwarf appears. If you don't, you'll get killed. (Be sure to retrieve the axe after you have killed the last dwarf that is with you.)
Don't worry if a pirate appears and steals your treasures from you. You'll find them again later on.

If all went well, you have finished with a maximum score.
If the pirate never appears, you probably won't make it. When you reach the dead end where the chest is supposed to be, you could backtrack (if you know how) through the maze and then forward again until he appears. If this takes too many turns your lamp batteries will wear out before the end game, and then it's tough beans.
