Don't even think about using a chainsaw on a stump !
It's plunge cutting (bad) in a stump that's likely full of rocks
(worse)

I'd hire the stump grinder.

Or if it was in the garden and I wasn't in a rush, drill and burn it on
the next barbecue as a logger's candle. X-shaped cut down the middle,
or else a few big holes broken through into each other, then stuff a
paraffin rag into the gap and and light it. The two vertical timber
faces facing each other burn pretty well, once you've got them going.
Pre-soaking a couple of weeks before with a nitrate solution helps too.


Not DIY, but I rang round a few people in the yellow pages when I wanted
a stump ground out in our garden, and the going rate was about 50 quid
to come and do it (this is in East Yorkshire). At that price it wasn't
worth hiring the kit to do it myself.

I watched our next door neighbour trying (for several weeks) to remove a
small tree stump using just about everything from fire to chainsaws and
decided it was 50 quid well spent.
