In standard, no Gazilli treatment or similar being played, the only way for opener to create a force after 1nt is to jump shift. Hence if you don't want to miss game opposite responder's minimum 6-8 pt hands, you have to jump shift. This includes jump shifting into 3 cd (sometimes 2cd!) fragments, and partner should cater to that possibility in later rounds of bidding, and not automatically assume 5-4 or 6-4. Jumping to 3M doesn't work since it's not forcing. Jumping to 4M is inferior because usually that is treated as hand with longer spades and less in high cards, and less suitable to alternate strains. It also robs responder of room if he has a good hand.
With the given hand, I see nothing wrong with a jump shift into 3c, planning to raise hearts, pass 3nt, & rebid/raise spades otherwise.
If opener bids 2c only, playing standard, not Gazilli, surely responder's percentage action is to pass, no? Opposite opener's much more common minimum holdings, anything else rates to put you into minus territory.
If you don't jump shift on this type of hand, you either commit yourself to spades when NT / hearts / clubs could be better, or you risk playing 2c with game on.
I don't see much risk in jumping to 3c, as long as responder is aware of this hand type being a possibility.
