2nd opponent will bid adjacent higher suit. So, if the overcall is 2 Clubs, 2nd opponent will bid 2 Diamonds. 1st opponent pass with long Diamonds, otherwise bids 2 Hearts and waits for his partner's choise. There is a problem with the 2NT overcall, because if the 2nd opponent will bid otomatically 3 Clubs, then he could not show his choise. So, in this case, 2nd opponent should make his choise at this point. If he supports Clubs, then he bids 3 Clubs, otherwise he bids 3 Diamonds. If the both minors are less than 3 cards, then he bids 3 Hearts. In short, he bids his first at least 3 cards suit.

If you want, you can solve this problem by changing the places of the meanings of 2 Spades and 2 NT overcalls.

If the responder bid anything after overcall, then 2nd opponent passes.
