Help
In our region a 2♣ opening like in 2/1GF is rarely used. I'd like to play this to keep my 2♦ openings weak. Normally we use 2♦ as positive and 2♥ as negative.
I'd like to know what agreements are used when opps intervene, preferably expert standard. What do you do when the bid natural, what do you do if they bid artificial (like suction for example),...?

I'm not sure there is an 'expert standard'
Here are a few things that are very commonly played:
- If intervention is passed round to opener, then double shows a balanced(ish) hand
- Unless you have already forgone a chance to defend a strain doubled or bid it naturally, then all 'cue bids' are natural (e.g. 2C (2H) 3H and 2C (2H) P (P) 3H). Unless you play somewhere that thinks it's cheating to psyche.
- As responder, you need to bid on any decent suit after 2nd hand intervenes even if you don't have the traditional values for a positive.
And a few other bits and pieces:
Agree what responder's double means after 2C (action) x. It is very common to play this as a double negative. Personally I prefer to play double as 'take-out' (about 4+ HCP without much in their suit) and pass as either wanting to defend or nothing. Either way round works.
You might be able to stop in 2NT in an uncontested auction (e.g. 2C - 2D - 2NT showing 23-24 - Pass) but if they act, just assume you are game forced. System is on after 2C (2-level action) P/double (P) 2NT.
In the later auction, or if they pre-empt, the forcing pass acts as a take-out double, typically a three-suiter. Balanced hands double, single-suiters bid their suit, 2-suiters bid NT if that's obviously artificial, or bid one of their suits.

My experience is that a direct double by responder is a bad hand. Opener is warned that he is essentially on his own, and, while the double does not show anything in the opponent's suit, it can be passed.
A pass of the overcall is game forcing.
If opener is not forced to bid (say, for example, that fourth hand bids something, or that the first intervention is by fourth hand) opener's pass shows a balanced hand.
It seems common these days to play all low level doubles as takeout, but I prefer penalty doubles in these situations. So, if it went 2♣ - (2X) - P - (P) I would play a double by opener as a penalty double.
