For instance, most players today bid five card majors, because that's (probably) the best way to get to a major suit game of ten tricks.
But suppose my team has a part score of 40. That means that two of a major or three of a minor will give us game. Under those circumstances, does it make sense to say that a one level bid implies four of a suit, major or minor? Because I no longer see the need for a five card major, and likewise, don't see the need for a "convenient" three card minor. Instead, every bid could be "gamegoing."
Likewise, I prefer strong no trumps. But could a weak 1NT (12-14 hcps) be better if we need to go only to the two level to complete the game?
Are there any systems or experts that advocate modifying one's bids in these, or similar fashions, with a part score?
