Several folks have mentioned in this thread that PCs should use specific strategies to avoid death in old-school D&D combat at first level.
"Using choke points, doors, and other obstacles to your advantage such that you don't get swarmed under by the hordes." is just the latest.
Although it's a good concept, death at 1st level in old school D&D can come even when Special Forces tactics are used. I mean, when
one hit could kill a fighter (not even a crit, or max damage, just a normal, average hit) there was no sure-fire safe tactic. Hell, winning initiative was a 50/50 chance.
All the "listen at the door," "draw them out," "throw flaming oil," etc. advice sounds wise (and smart alec), it doesn't ensure survival.
For instance, what did Frederick do wrong in this example of BD&D combat:

What did Morgan do right that kept her alive? Or was it all mostly luck that made the difference for them?
