2♣ says " 5+♣,10+hcp,16-TPs ".
Only five cards suit? If it really is 5-card suit,2♣ will be very danger. I think it is impossible.
At least,2♣ must be a decent suit with 6+cards.
Decent suit should have 3 of 5 honors and 2 of 3 top cards.
So I think the definitions of 2♣ is 6+♣ with 2 top cards,10+hcp,16-TPs".
