Attacking the mutant pawn island feels natural. Strategically, I am not so sure this is best(USCF 1450).
If the aim is to create a passed pawn on the kingside, then attacking the isolated -a pawn would be more to the point.
Attacking the -c pawn triplets would still be worth while. Those squares can be used to further attack the isolated -a. Taking control of the c5 square would give white more space to work with. If white takes control of c6 black could be in serious trouble. The ideal set up to accomplish this would be to have one rook or both rooks doubled on the c-file, bearing down on any isolated pawns, and more importantly the 7th rank.
The b-file and d-file are open, raising concerns for whites king safety. Black could attack by opening the a- file and the a1-h8 diagonal. If black were to push the -a pawn to a4 either the a-file would become open with a trade and/or white would lose its anchored pawn on b3. The black rook(s) would then glare down onto the 7th rank via the a-file or b-file weaking whites king position. Black opens the a1-h8 diagonal with f7-f6, trades bishops, places queen along these squares aiming it toward whites king. Then, the black queen and rook(s) could work together threatening whites king. Also, black could attack with the queen via a3-f8 diagonal with a push of the c5-c4, looking to place the queen on a3. This plan would stop white from gaining a passed pawn (with a favorable position) on the kingside.
Will this plan work? I don't think so. White will lift the f1 rook to f3, defending b3 and eyeing a shift to the c-file attacking the isolated pawns or h-file for an attack on blacks king. I could see it happening like this:
The white queen covers a5.
A combination with Nf6+ looks troublesome and it helps prepare a f7-f6 push.

Anyone care to analyze this position? White should still have the advantage.
