Lionel convention

Lionel is a contract bridge bidding convention used in defense against an opposing 1NT openings. Using Lionel, over a 1NT opening of the opponents:

Any of the overcalls denote high-card strength corresponding to 12+ (or good 11) high card points.

The convention is named after Lionel Wright from New Zealand who published it in the International Popular Bridge Monthly magazine of May 1993.

Responses

Following the Lionel double, the partner of the double responds as follows:

(1NT) - dbl - (pass) - ??

After a minor suit Lionel overcall, the responses are straightforward. For instance:

(1NT) - 2♣ - (pass) - ??

Advantages/disadvantages

Like using Brozel, CoCa or DONT, using Lionel has the consequence of losing the penalty double over opponent's 1NT. Although this is often seen as a loss, Lionel Wright argued that this loss turns into an advantage as it opens the possibility to defend 1NT doubled with split points between you and your partner. As a balanced holding of the majority of points is far more likely to occur than holding the majority of points in an imbalanced way, a conventional non-penalty double over 1NT holds the potential of paying-off on many hands. Also, non-penalty doubles are more difficult to deal with than traditional business doubles.

Fiji disease virus

Fiji disease virus (FDV) belongs to the reoviridae family and infects plants. It is one of the few plant viruses in the Reoviridae family. The type species of the genus Fijivirus, it is the only known member of Fijivirus group 1.

Structure

The virus is between 65-70 nm in diameter. FDV is not enveloped but has a nucleocapsid. The capsid has two layers and is icosohedral. The two known cell surface proteins are A type and B type spikes. The capsid appears round.

Genome

As FDV is a reovirus its genome is also made of dsRNA. The genome is linear and made up of ten segments, consisting of 27000-30500 base pairs. There are at least six structural proteins coded for in the genome. Replication occurs in the host cell cytoplasm or cytoplasmic viroplasma.

Transmission

The virus is transmitted by Delphacidae plant hoppers. The disease is mostly found in Australia because this is the natural habitat of the plant hoppers. It has also been detected in the Philippines. The virus infects the phloem tissues of their Gramineae hosts. Replication can occur in both the host and vector. The result of infection in plants is the development of tumours.
