The VA 'Two over One' system has some gadgets. It is "work in progress".
Jump responses are usually weak; sometimes they are used to describe specific features.
Weak jump raises and weak jump shifts are used extensively.
The principal of fast arrival is used. For example, if a game force has been established and
we have a minimum hand, we bids game; with more he bids slowly.
The Law of Total Tricks is used to as a guide to ascertain the level to jump to.
A response of 1 NT to a major is forcing for one round and is semi-forcing by
a passed hand.
If in a cue-bid situation, and you are not sure that your partner's bid is a cue bid or not,
bid on.
This way you will not leave partner in a cue bid and will make the one level higher
contract.
A sample of the 'Two over One' card will be presented below later.
