We could still have a 4-4 heart fit, def don't agree that hearts is a cuebid.
I think spades is a cuebid. Clubs is either our only game try (if X is not some game try), or natural (if X is a game try).
So I guess my answer to the OP would be "spades"
I dont think just because we can have 4-4 fit justifies a bid to be natural when one of them is known to have 4-5 of this suit, especially at 3 level. The chances of finding
♥ fit when one of them showed 4-5
♥ is reduced, and even if you find a fit you know it will split 4-1 or on a bad day 5-0. Also the simple 2
♠ bid by opener usually means a balanced hand, so i expect him to hold at least 2 hearts most of the time. Do we really want to use this bid to find a 4-4 fit ?
On the other hand you can of course convince me that playing this 3
♥ as cuebid has less merits than using it as natural. Something which i didnt really think about much tbh.
