Maybe 3325 was a bad example, but I didn't have a point so much as a question. On what shape with 3 hearts will responder have to double then pass a 4♥ bid?

good question, IMHO. Based on what I think a resp double should look like, there isn't a hand with 3 hearts which would pass 4H. with 4315, he would remove 4H to 4S and original doubler would take a choice between spades and clubs. Other than 4-3-0-6, can't think of another resp double without 4 hearts.

Of course, that might fly in the face of those who think the resp double can be left in without a huge balanced hand for the original double and without multiple diamond tricks. It goes back to respect for the original double of 3D.

So if we can agree the second doubler never passes 4♥ with just 3 hearts, then we can also agree bidding 4♥ on 5413 is guaranteed to find an 8+ card fit? The worst the happens is you play an 8 card heart fit with a 9 card spade fit on the side, but bidding 4♠ on 5413 gets you to clubs when partner is 2434 or 2425 or something.

yep, that part seems obvious to me, once we agree that a hand with only one place to play (4 3 3 3) opposite a 3DX would just take his chances and bid 4S, not a responsive double.

(3♦) - X - (4♦) - X?

I think it just says I have some good values and no clear bid available and defense is certainly a good option. So the first doubler should sit the double with most balanced and semi-balanced hands. The doubler shouldn't expect that partner may hold a good 4 card major suit IMHO.
