The traditional minor-suit raises show important limitations: With a weak raise you will almost never play a part score at level 2, so it is desirable to bid 3, to preempt the opponents. With a good raise you need more room to explore for the best contract, so it is desirable to bid 2.The solution more and more players adopt is to “invert” the meanings of these raises. With or without interference, With the 'inverted Minor Raises' convention :A jump raise to 3 ♣ or 3 ♦ shows 6-9 points and a 5 cards fit.A raise to 2 ♣ or 2 ♦ shows 10+ points, a 5+ cards fit, no four-card major, and is forcing for one round.
