2H/2S Preempt with/without interference


1. Open 2H/2S a Pre-empt


2/2♠: good 6 card suit to 2 of top 4 honors, 5-9(10) HCP majority in major, no more than a A or K outside, a 1-suited hand (sometimes a 4 card minor but not a major). Avoid opening weak two bids with 6-4-3-0 distribution as it will be too difficult for responder to judge the best course of action when you have both a side four card suit and a void. Qx or Qxx or better should be enough that there is likely at most 1 trump loser. With trump quality being better than a minimum in standard I feel no need for Ogust. Asking for a singleton is more useful as this feature does not take away from the strength of the trump suit. So, if opener does have a singleton and responder is interested in slam it is a distinct possibility.
