MOSCITO, that makes extensive use of limit bids, relays, and the shape defining properties of Zar Points to rapidly describe a hand. Below is a summary of the basics, omitting some of the finer points and the research details supporting the decisions. To make this a full system, a partnership would need to agree on what conventions to use. Most of the ideas from other systems can carry over. Partnerships interested in using this system should familiarize themselves with the reasons behind this basic bidding pattern before selecting specific conventions. Opening bids Opening bids are divided into three intervals: just enough to open (26-30 Zars), one extra bidding level (31-35 Zars), and two or more extra bidding levels (36+ Zars). Because distribution can dramatically affect the playability of a hand, each of these Zar Points ranges can cover a wide number of traditional high card points. The opening level could represent between 3 and 19 HCP. The middle level could represent between 7 and 22 HCP. The maximum level could represent between 11 and 30 HCP. These ranges are inclusive. These three ranges are statistically derived: 60 percent of opening hands will fall in the lowest range, 30 percent will fall in the middle range, and 10 percent will fall in the top range. 1: 36+ Zars, any distribution or 31-35 balanced 1: 31-35 Zars, any distribution or 26-30 with a 6-card minor 1: 26-30 Zars, 4+ cards in hearts, may have 4 cards in spades 1: 26-30 Zars, 4+ cards in spades, may have 4 cards in hearts (and 5 in spades) 1NT: 26-30 Zars, no 6-card suit, no 4-card major, no 5-5 minors 2: 26-30 Zars, 6-card heart suit 2: 26-30 Zars, 6-card spade suit 2: 26-30 Zars, 5-card heart suit and a 6-card minor 2: 26-30 Zars, 5-card spade suit and a 6-card minor 2NT: 26-30 Zars, at least 5-5 in the minors 3: 26-30 Zars, 7-card club suit 3: 26-30 Zars, 7-card diamond suit 3: 26-30 Zars, 7-card heart suit 3: 26-30 Zars, 7-card spade suit 3NT+: 8+ card suits Responding to opening bids Because of the very descriptive nature of each of the opening bids, the responder is in control of the bidding unless the opener bid 1. Also, the responder will be able after the re-bid by the opener to estimate the misfit modifier, allowing an accurate determination of where to play the hand.
