1♠:2♣
2♥:4♥ (presume 3♥ would have been NF)
5♥

What does it ask for and why?

In a normal auction, the bid of 5-trump asks for one of 2 things: Control in the unbid or opps suit, or trump quality if an unbid suit does not exist

Since 3 suits have been bid, this bid asks for control in the diam.

Replies are:
pass = no control
6D = ace or void
5N = Kx
5S/6C = ace + king of suit bid
6M = singleton

I would take it as lack of ♦ control, mainly because you can use 4NT to get trump honnors.

I think it depends whether your Key Card can handle a void. If yes then 5H can't be asking about hearts. If not, then I guess five hearts is asking about hearts.

first i think this ask to play 2/1, so you dont have this problems

but in current position, lets investigate more:

if i need ♦ cuebid, i would bid 5♣, waiting for 5♦ to bid 6.

if i need ♠ control, how i would bid? 5♦? possible

if i need ♣ control, how i would bid???? probabily i would make inference my partner have after 2♣ bid, so i pass this question

if i need ♥ honours and if i have a void in ♦ (so my rkc is not good) i think i would bid 5♥...so this should be the meaning...

Standard: voluntary 5M asks for:

1. control of the opponents' suit
2. else, control of the sole unbid suit
3. else, two of the top three trump honors

I don't think the "responses" to this are universal, but it does make sense to cuebid if you have the ace or void and the partnership could still have grand values.
