They're smart & cunning and they're generally fighting on their home turf. They'll have superior numbers. That's the same combo that allowed poorly armed Afghanis to kick the Soviet Army out of their country.
Um...
Seriously, where do people get the idea that kobolds are smart?
I don't see a +2 modifier to their Intelligence, after all. They're average, like almost everyone else. They're not *stupid*, but neither is the average human.
They make mistakes like everybody else, like needing to breath (cast
cloudkill at the top of their ventilation system), or going out to raid (cut them off and slaughter them to a dog-lizard). Sure, they can afford to spend lots of their own, for each adventurer they take down, but competent adventurers will pull back and heal, and it takes time to replace dead kobolds.
Personally, I'd use a wand or two of
Summon Monster III. Nothing like a bunch of small elementals cruising through your tunnel to make a kobold's day painful, ugly, and short.
