Pillar dancing

The act of moving around a piece of unwalkable terrain, preferably a 1x1 'pillar' of rock, such that an opponent is forced to chase you round and round, so that they (hopefully) never get a chance to actually attack.

Since in many Roguelikes resources like Hitpoints and Mana recharge slowly over time, the idea is to delay an attack until the character has hitpoints to survive at least one attack and/or enough mana to cast one spell. (If the opponent is still alive at this point, one generally returns to pillar dancing.)
