Playing in a Swiss teams event of somewhat mixed quality I pick up this hand:

I am South and the hand on my left is dealer at love all. Hoping that the bidding will be allowed to develop gently I am alarmed to see it proceed at high speed: 1spade on my left and 4spade on my right. Ugh. Now what?

     W     N      E     S
    1spade    P    4spade    ?
