I've seen a lot of ambiguous preemptive methods over a strong club, things like suction or psycho suction or DONT. Since everyone (or at least the regulators) seems to whine about how hard 2♥ non-forcing multi is to defend (in contrast to forcing methods like suction or naturalish methods like DONT), have people included this multi bid as part of their defense to a strong club? If so, what do you use the rest of the defensive overcalls for, to go well with this?

What about similar ideas that instead of 50-50 are 2-out-of-3? Something like

2♦ = 2 suits from clubs/diamonds/hearts

You are actually even more likely to be able to pass (than a 50-50 bid like multi) since now there's an a priori 2/3 chance that partner holds his suit bid.

Just for fun we used to play this many years ago:
(1C) 2C = weak in next higher suit, or 5/5 with this suit and 2 above, or 4441 with a singleton in the bid suit.

Nowhere near as effective as canape overcalls, however.

The so-called HOLO / BOLO / ROLO / etc. interferences are popular among Dutch juniors. Some include a 2♥ overcall showing hearts or spades.

Just for fun we used to play this many years ago:

2-level jump overcalls = weak in the suit bid, or a 3-suiter short in the suit bid, or a specific 2-suiter not including the suit bid (I can't remember how you defined the 2 suits any more)

We still sometimes play 2-level jumps as either weak and natural or a 3-suiter excluding the suit, but we pick our opponents carefully.

I like Amsbury JO to 1C-artificial:
WJO sits X;
1444 redoubles;
5-5 bids one of 2-known suits.
Add Paradox-like responses(pass/correct raises).
