Diamonds are longer than clubs, so they open 1D.\n\nResponder wants to get to a NT or major suit contract. They have a 4-card heart suit, so they bid 1H.\n\nOpener has 4 hearts and 4 spades. Knowing that responder might have bid \"up the line\" with two 4-card majors, opener shows their 4 spades by bidding 1S.\n\nResponder denies also having 4 spades by bidding 1NT.\n\nOpener doesn't know responder's points, so they bid a cautious 2H to show that they also have 4 hearts.\n\nResponder knows that opener had opening points of 12/13+, and that the pair has 25+ points--enough for game. With those points and an 8-card heart fit, responder bids 4H."}
