Scottish GM Paul Motwani gives this as a sidebar position in "The Most Instructive Games of the The Young Grandmasters" -- he gives the diagram above and writes:

"Why can Black's position at move 16 [the diagram] really be described as "hopeless"?  Well, in effect, White is already a pawn up because he has an extra unit on the queenside, whereas Black's doubled f-pawns are fimrly blockaded by the f5-knight. Futhermore, if Black captures that piece with 16...Nxf5, then after 17 exf5 White will soon plant his remaining steed on the outpost at e4, and the winning plan consists, quite simply of creating a passed pawn on the queenside." 

Sounds just peachy in theory, eh? ... but against a strong engine it is by no means, a 'gimme'

My questions -- is this an appropriate sort of position for what you are looking for, Erik?

Is it possible, or desirable, to give GM Motwani's notes (rewritten to avoid copyright issues of course) to the solver as an aid?

there will be no notes given in our positions. perhaps a brief description of a plan, but not much more. this is a good example of a very complex version. i would prefer to knock out the basics first, but this works for more complex :)
