removing a damaged screw

[Odds]

I have a large cupboard i'd like to take off the wall.
It's held in place by three screws at the top and two at the bottom: the top three can be moved with effort but only one of the bottom two will shift; the other won't budge because the head was stripped by the guy who put it in place and no amount of twisting with mole grips can move it.
Is there a way to move a 'headless' screw withut cutting it?
It's very difficult to get a blade under it and little room to move, either.

photos might spark ideas.

is the cupboard to be scrapped?

Drill the top off then grip the remaining shaft with mole grips once the cupboard is removed.

I'd like to use the cupboard for a cold frame so i can grow seedlings - and i'm not sure a photo will help much.
And i'm loathe to drill the top out as i cannot get a good grip with the mole grips as it's in such a tight spot...i may as well try cutting the head off in that case and that will end up damaging the wood. It is under the base of the cupboard so it won't be noticeable, but still i'm averse to damaging wood on principle.

I find gripping the Head with Side Cutters works well with Damaged Screws. Used this method for DIY and Repairing Electronics may times.
As if you were trying to cut the screw is half along it's length.
Gets a better grip than Pliers or Mole Grips.

try it.

do you own a hole saw or a multicutter?

I have a Dremel which is used with grinding discs to cut new slots in cream crackered screw heads. Works well

I took one last crack at that stuck screw this morning and lo! thar she blows!
With the mole grips ratched down to their lowest setting i finally got a firm grip on the screwhead and, with slow half-turns, managed to loosen it enough to bring out the whole thing.
With great relief the others came out easily enough and a firm pull on the cupboard brought it safely off the wall.
I'm sure you're all releived to learn alls well that ends well.

It's good to get feedback on the eventual outcome of a problem.
So many times people ask for, and are given, advice on how to tackle a problem but more often than not we never get to know if they used any of the advice to solve the problem.
Thanks for letting us know the outcome.
