Do we go for three streets on safe runouts

Blinds £1/£1

Hero opens KhQd in MP to £3 (300bb) covers
HJ (100bb)
CO (150bb)
BTN (200bb)

All three seem pretty new to game. They haven't shown much reason to think they're regs.

I'm not thrilled with the turn as they could have 9x of clubs and 910s J9s, If we get called do we still go for value on safe rivers?
