Sitting south in 3rd hand you pick up [hv=d=n&v=n&s=sxxxxhxdkqxxxxckx]133|100|Scoring: MP[/hv] Partner passes, RHO thinks hard before passing as well. 2♦ would be artificial, forcing to game, so that's no option. Partner will expect you to preempt aggressively as far as suit quality is concerned, but has never seen you preempt on the 3 level with 6 cards. So if you bid 3♦ you can expect to be raised if partner holds more or less any hand with 3 diamonds. Bonus question: Does RHOs hesitation have an influence on your decision? Olaf
