I've been thinking about the tactics that would be used by some of the weakened humaniod races, like kobolds and goblins. I believed hit and run would be their main tactic thereby avioding melee and/or pitched combat at all costs. But adventures have an tendency to invade the lairs of these humaniods, how would the "monsters" respond? Their lairs offer a limited space so hit and runs would become less and less useful. Traps could and would be their best defense but are expensive and, the most lethal, could cause major damage to their homes.
Besides traps and small tunnels, how would they defend their lairs?
