After we open 1 or 1 and partner raises to 2, what should we do? We should add at least a point to our original evaluation, because our 5+ card suit is now worth more. For example, K10765 might not be worth much opposite a singleton, but knowing partner has support (picture QJx), means we have lots of tricks in our suit. With a re-evaluated strength of less than 16, game is unlikely (facing at most 9 or a so-so 10). With about 16-18 in strength, we want to invite game. This is done by bidding a new suit (typically something like Axxx or Q10x -- where you want partner to evaluate his cards in that suit to help with marginal decisions). A re-raise (1-2-3) should just be a blocking bid--based on the LAW of Total Tricks--not invitational. With more than 18, opener just bids game (no need to give away extraneous information). What if the opponents interfere after the raise? After 1 (Pass) 2 (3), opener can bid 3 just to compete (not invitational). To invite game, he has to bid a new suit (in this case, the only try is 3--and says nothing about hearts). What if the opponents overcall in the suit one below opener's? For example: 1 (2) 2 (3) ? In this case, 3 is needed as just competing for the partscore (not inviting game). If opener wants to invite, the partnership has to use "Game-Try Doubles"(also called "Maximal Doubles") -- whereby double of the suit 1-under is not penalty, but invites game. In all cases above, responder would bid game with about 9-10 and reject with about 6-7. In between hands require judgment.
