Everyone loves the pre-emptive value of a 1NT opening bid. It is therefore essential for opponents to have a good method of getting into the bidding which balances ease of use with frequency of occurrence. The presenter's preferred method is Landy which uses 2C to show both majors and leaves 2H and 2S available as natural bids.
The presenter does outline other options but emphasises that whatever is played, not only should both players play the same but it must leave room for a natural bid in the majors.
This is a straightforward system that is easy to use. A lot of the subtleties occur so infrequently that no one should have any trouble playing this.
