What type of hand would justify a 3M or 3m opening after 3 passes to you?
Is it a part of expert systems? If so, what should excite partner?

Thanks.

A bid for every hand, not a hand for every bid. What hand type doesn't want to pass and isn't served well by opening something lower in your system?

I've played this as very concentrated intermediate (13-16 HCP) hands before with a strong but non-solid 6 card suit. It never comes up, and I've seen experts struggle the few times it does. I think partnerships are certainly better off leaving it idle. Some people are allergic to that idea though.

If you open 1♥, you'd be willing to compete to 3♥ just on the shape - not strength - of your hand, and are afraid that if you do open 1♥, they'll find their suit to compete in.

p-p-p-1x auctions tend to get very noisy very fast. p-p-p-3♥ auctions, it's just harder.

Which leads to effectively what DavidKok describes - "looks like a 3♥ preempt, just with enough cards for a minimum opener (and by its nature, not a "third-seat preempt" or "first-seat NV preempt" suit)."

And yes, like any "preempt" it can cause your side problems as well, when the right 10 count makes slam, or when they do compete to 4♠ anyway (say because dealer has a hand that "would have preempted except" too).

Okay, agreed it is too rare to matter. I had in mind something like an approx. 8 trick hand with one of top-3 trump honor missing -- partner expected to surely have at least one quick trick on the bidding. If he has more, he can bid game. For example: xx, AQT9xxx, Ax, Ax. If we open 1H and is overcalled 2D, partner may not be able to bid game with something like xxxx, Kx, xxx, KQxxx. If it gets raised to 3D, we may not bid 4H fearing wasted spade or club values. Apologies, if it sounds silly.

I would strongly favour opening 1♥ in the 4th seat with this hand. Not sure if others agree, but in my opinion this hand is too strong for a 3♥ blocking action.

More like AQ109xxx and AQx

You could also blast 4H.
As it is, you need useful cards, and the question is, can you find out, if p happens to hold those?
With 14HCP, p will have on avg. 8, with 2 useful cards you will have play.

A minor suit preempt should mean, p bid 3NT if you have the other suits more or less controlled,
... 2 out of 3 may also be ok, they may still need to find the hole facing the lead,
and have secondary support for the opened minor. Lots of bal. 10 count would fit this req.
