North 1[spade] ?  
South 1NT

Another tough hand….don’t you guys ever just deal a regular hand! I would bid 4[spade]. Sure, you might go down. Partner might hold a void in spades. South might have all of their HCPs in clubs. However, you don’t need much to make a game…for example the [diamond]K and two small spades might be enough and how are you ever going to find out that partner holds that? Even the [heart]A and [diamond]J and one spade might be enough. I could go on and on…but the simple fact is that there are a lot of ‘bits and pieces’ of cards that South might have that would give you good chances to make game. Bid ‘em up!
