our 1c opening is 15-17 unbalanced or GF or clubs 15+ or 15-17 bal
i consider south hand worth 18 pts
so opening 1s and jumpshifting.
we relay all our jumpshift.
1h ---1s ?relay
1nt---clubs 12-14 or 18-22
2c-- diamond 12-14 or 18-22
2d 6hearts 12-14 or 18-22
2h spades 12-14
2s+ 18-22 bal+ 5h+4s jumpshift.
So for us the south hand is too strong for a 1c opening
same kind of hand where a underbid of 2clubs give a better chance to reach slam then the value bid of 3 clubs.
