East is the dealer. Bid the E/W hands. Should you splinter?

Gino's Suggestion and a Short Explanation
Responder's 4♣ is splinter, showing shortness in clubs and a heart fit. Responder would splinter directly if he/she held 4+ hearts. Note that with real clubs, responder could rebid 3♣ as a forcing bid. No need to jump in game forcing auctions. The splinter bid helps the opener who holds 2-3 losers in clubs and no wasted values. Opener then takes control by bidding RKCB.
Note: The partnership could bid the slam without using splinter. However, the splinter - if recognizable by partner - simplifies the hand evaluation.
