Partner has 3 card support. Now?
(As an aside, I struggle to see how a non GF 4SF would work in this situation).
Now you bid 4C, this sets clubs, and showes SI. 3H should pinpoint a 5431 distribution with opener.
And it does not matter, that FSF was not GF, ..., the only difference is,
that non GF implies, that you could end up in 2NT (would show a min opener with a spade stopper),
opener would need to bid 3NT, 3C could be passed, if opener wants to force, he needs to bid 3S.
We play 2S as non GF, ..., but a 3 level response turns the auction GF.
The thing is, lots of peoble have no problem, that a GF FSF forces you sometimes to stretch, if
you hold "only" inv. values (hands, that were the main reason FSF got developed in the first place),
sometimes you will force to game.
