IMO 5♥ = 10, P = 8, X = 6. Partner did not cue ♦, so probably has long ♥.

The way I learned responses to takeout doubles--and a quick Google search of "responding to takeout doubles" suggests that this is standard--a single jump response shows 9-11 (does NOT promise a fifth trump), a double jump shows 6-8 points with a six-card suit, and a jump to game shows 12+ "dummy points". This last point is why I disagree with nige1's assessment; I don't believe partner's failure to cuebid indicates anything in particular beyond the conviction that 4H is the best contract. The way I learned it, a cuebid in response to a takeout double could be a couple of different things: an invitational or better hand with equal length in both majors, interested in finding the best major fit; OR, a game-forcing hand with no clear direction, that wants to find out more information before deciding on a final contract (it might want to leave open the option of 3NT if partner only has three cards in our four card major or something). Rarely, it could also be a single-suited hand interested in slam, but that is pretty remote. Partner doesn't automatically cuebid if he knows what the best contract is likely to be. For example, why should a hand like xx/QJxxxx/Ax/Axx cuebid? Doesn't 4H rate to be the best contract opposite a normal takeout double? Why not bid it and put maximum pressure on the opponents?
Like Dave, I was taught that, with four card support for one of the doubler's presumed suits, you should
limit-raise. For example after (1
♦) _X (_P) ??
- 1♥ = Natural limit. 4+♥. 0-7.
- 2♥ = Ditto. 8-9.
- 3♥ = Ditto. 10-11.
- 4♥ = Ditto. 12+.
I've revised that opinion, for low-level auctions. If you have the luxury of bidding space, you may as well use it, reserving jumps for more pre-emptive hands.
A
cue-bid seems an efficient way of showing most hands with the high-card values for game, even with four cards in some of partner's putative suits. If partner has a mountain or if opponents compete then you allow partner to exercise better judgement.
Nevertheless, I agree with Dave that, when you fear competition, it is often tactically right to jump, with a long suit, even with a good hand. For example 4
♥ seems reasonable with
♠ x
♥ KQJxxx
♦ Axxx
♣ xx.
More controversially, I like
constructive notrump advances with
system-on after partner's double:
- 1N = Natural Flat. May have 4-card major. 8-10.
- 2N = Ditto. 11-12.
