Notes when North is Dealer:
- P1, P8: 8 HCP, but no 5-card suit.
- P18, P22: 18 HCP, bidding the cheaper of his two 5-card suits.
- Only 3 HCP and a 5-card suit.
- In response to 3 of a suit, 3 of a new suit shows a 4+ card suit and 3-13 points. He has club support, but a bid of 4♣ would deprive the pair of the opportunity of a 3NT contract.
- East should not bid 3NT unless he has all unbid suits stopped. Instead he bids his other 4+ card suit, as cheaply as possible, showing 17-19 HCP.
- West takes the view that slam is unlikely because East has denied a heart stopper. So he shows his club support.

Notes when West is Dealer:
- P14: As a test of Simplex's dealer-independence, we examine the bidding when the dealer is South instead of North.
- P8: 12 HCP and no 5+ card suit.
- P8: No 5+ card suit but only 8 HCP.
- P18, P22: 17 HCP and the cheaper of the two 5-card suits.
- With only 3 HCP and a 5-card suit, you are not strong enough to open or respond, so pass.
- Opposite a 3-level suit bid, the 1NT opener now bids his cheapest 4+ card suit.
- It is now clear to both East and West that the hearts are unstopped, so East bids past 3NT by showing another 4+ card suit.
- West ends the auction by showing his support for East's original suit.
