I assumed that the good/poor thing was burn/start also.
If you dont burn your stove HOT then creosote will attach itself to the chimney. Now, you may have some flame but coals is where the heat is at. Green wood wont make coals. Burning green on and off without ever burning hot is asking for buildup.
If you smolder without enough heat, the only thing you do is put the creosote farther up the flue.
The easiest way to avoid a chimney fire is to burn hot and and clean the chimney.

Chimney fires don't have to happen. Here are some ways to avoid them :
Use seasoned woods only (dryness is more important than hard wood versus soft wood considerations)
Build smaller, hotter fires that bum more completely and produce less smoke
Never burn cardboard boxes, wrapping paper, trash or Christmas trees; these can spark a chimneyfire
Install stovepipe thermometers to help monitor flue temperatures where wood stoves are in use, so you can adjust burning practices as needed
Have the chimney inspected and cleaned on a regular basis

I dont agree with all of the easy to split info either. If you compare oak to maple though the maple is way eaiser to split. I can pop either pretty handily, but the oak asks for more oooomph to the maul.
