Hand 1 :
100% pass in seat 1, 2 and 4.
In seat 3 3♥ is ok (I would pass because of the 8 LTC).
A good agreement is that after first passing a jump overcall (or response on partners 1♣/♦ openings bid) shows at least 6-4 in the majors.
Hand 2 :
If you agree that no aces are allowed outside the 7 card than pass or 1♥ (not a fan) is your only option.
I would open 3♥ in seat 1-3 (0-10 HCP 6-7 LTC) and on agreement 2♥ in seat 4.
Hand 3 :
I would open 3♥ in seat 1-3 (0-10 HCP 6-7 LTC) and on agreement 2♥ in seat 4.
Aawk makes a good point: after three passes, you don't pre-empt. Ever. Why take a bid where you expect to go minus when you can just pass out the hand?
However, there is a standard meaning for a fourth seat, two level call in 2/1, SAYC and Standard American: six cards and the minimum HCP's your partnership requires for a one level opener. GIB plays 10-12 HCP; the original concept was more like 12-14 HCP. The original idea was to make a picture bid, attempting to find skinny, distributional games opposite a passed partner. Now the trend seems to lean toward part scores.
So pass hand #1 in fourth seat. Hands #2 and #3 barely qualify for a 2
♥ bid (if partner has agreed to fight part score battles like this), particularly since it's a near guarantee that partner has 10-12 HCP. The downside would be that the opps have most of the HCP, and probably the spade suit.
