Notes when West is Dealer:
  1. P8: 12 HCP and no 5+ card suit.
  2. P8, P11: With 14 HCP and no 5+ card suit, North would have bid 1NT himself.
  3. P9: Because of his spade void and red-suit strength, East uses one of the three gadgets in the Simplex arsenal — 2♣ Redshift — which invites the 1NT bidder to reply with his cheapest 3+ card suit. Because the 1NT bidder has no 5-card suit, the answer will always be 2♦ or 2♥, which East will pass.
  4. P2: South is permitted to bid a 5-card suit at the 2-level on the first round only because it is in response to a double.
  5. West has already bid his hand, and besides, South's intervention ensures the bidding returns to East, in case he has something juicy to offer.
  6. P16: With 12 HCP and four spades, North can support South with the forcing Simplex 2NT.
  7. East is far too weak to bid now.
