J-Moscito is a variation of Moscito (Major Oriented Strong Club), originally invented by Paul Marston and Stephen Burgess. This version was developed by Mr. Jari Böling (website and source) and presented is the revision of October 22, 2002, This original version is based on the concept of Honeymoon Moscito authored by Mr. Peter Buchen with the titles Moscito 2001 and Moscito 2002, and as described by Mr. Richard Willey and discussions with Mr. Kurt Häggblom. This information has also only been preserved and archived on this site in .pdf file format for future reference.

The distinctive feature about the J-Moscito opening bids is the fact that one set of opening bids is employed in either first or second seat, whereas a second set of opening bids is employed in either third or fourth seat. The following outlined opening bids, as stated by the author, also include the rate of frequency as determined by the dealer program of Mr. Hans van Staveren.

Transfer openings in 3rd and 4th seats would often lead to trouble, and relay bidding is also quite unlikely against a passed hand. Thus, relays are only on after an 1 Club opening, and other openings are quite natural.
