It seems to me that the Dwarves really had no clue what the creature was, and where he lived, and what were his habits, his abilities. The orcs, being more familiar with some of these things, would have the simple strategical advantage of thinking ahead.

Hmmm...were there "countless orcs" in Moria? If so, what did they eat?
I can't recall any given number. And as far as Orcs being strategic and thinking ahead, I don't believe there are many cases where Orcs displayed Napoleonic stratagems to defeat a foe, particularly one like a Balrog who, of course, is a Maia -- and one with wings!
