Notes when South is Dealer:
- P0, P1: 5-card suit, 15 HCP, 9 cards in two longest suits.
- P4, P1, P3: 5-card suit but only 6 HCP.
- P10: 3-card heart support and 8 HCP.
- P8, P11: With his 11 HCP and 4-3-3-3 shape, East wanted to bid 1NT, but North's bid has just taken this bid away from him. So he doubles.
- P12: North has made a limit raise and South has just the five hearts promised by his opening bid. Game is not on, so he passes.
- West now gets his chance to bid his 5-card suit.
- P11: North has bid the full extent of his hand already.
- As has East. He is minimum for his double.
- South takes his chances, based on his high point count (15 HCP) relative to the 8-16 HCP range his opening bid implied. This is the optimum contract, because 3♥ by N-S goes off one, whereas 2♠ by E-W makes.

Notes when East is Dealer:
- P14: As a test of Simplex's dealer-independence, we examine the bidding when the dealer is East instead of South.
- P8: 11 HCP, no 5+ card suit.
- P11: South wanted to bid 1♥, but East's bid has taken that away.
- P2: West cannot immediately bid a 5-card suit at the 2-level, so he employs one of the few gadgets in Simplex: 3-card Redshift. West will rebid 2♠ on the next round, if the bid is still available.
- P11: North was planning to bid 2♣ himself — his cheaper 3+ card minor — so doubles instead.
- East bids his cheapest 3+ card suit in response to the 2♣ gadget.
- South bids his 5-card suit.
- West makes the planned 2♠ bid.
- It is up to North whether he passes or shows support for South's hearts.
