I found somewhere (very likely in Gazzili by Lauria from NewInBridge) that Lauria-Versace in sequences 1H-1S, 1H-1NT and 1S-1NT rebid 3 in minor with 5M-5m and 15-21HCP range. Any ideas how to bid afterwards?

Cannot really find the topic on forum that would answer my concerns. Playing ekren 2d (weak majors, at least 4-4) how to go into slam bidding? For example: 2d - 2nt (asking) 3s (5s-4h) - ? Now how do I agree hearts as suit and start cuebidding? Maybe I shouldn't bid 2nt if I wanted to agree hearts regardless of the opener's shape? M.
