West will open a weak 2♠, the 6/4 shape (Kaplan evlauator shows this hand is worth 7.9HCPs!)  bid more combined with NV versus V for those doubting to open.

North will want to bid either with a double or with 1 3♥  (even with the Q♠ singleton)

Over both bids East will raise to the leval of fit. by bidding 3♠ 

Over 2♠ -3♥ -3♠ South will probably double to show the minors

North will bid 4♣ and South will raise to 5♣ or bid 4♥ showing 2♥ s.

Over 2♠ -x - 3♠ South will double to show values and minors, denying 4♥ s (with 4♥ s he would bid 4♥ s).

North may bid 4♥ s showing 5+♥ s or 4♣ 

E/W bidding may stop N/S find their game contract or higher scoring ♥ versus ♣ .
