You are right,3s should be forcing.(I forgot it on table since i have no experience playing system without 2/1 FG)But i don't think 3s promise a semi-solid suit.Opener's hand is the one in http://bridgewinners.com/article/view/bidding-problem-5647/ .Please make comment there ...
I learned Vasilevsky convention from Marshall Miles' book ,it makes some sense here.
2c,transfer to 2d,then bid 2h.Show exactly this hand.
Whether this hand worth to compete in is a more important question,but if you decide to come in,Vasi works well.
‘regional standard match’ may not be a good exprss.I don't really know how to describe game environment since i am not an experienced player myself.It's an Chinese national open pair match,but no professional players in general.
