Intuitively I would think that this line should just be a better (for black) version of the usual Mar Del Plata KID, seeing that the white c pawn is less advanced and the knight is somewhat passively placed on d2, and that black therefore should simply go on with the usual f5 push. However, in the few practical games I've had, this has not worked out for me so well, and I see the engine is actually recommending c6 (after many logical next moves from white), which strikes me as a tad odd position ally. Is there somehow something in this position that makes the f5 plan less attractive than in the Mar Del Plata?
