Hi all,

 

from BRIDGE WORLD STANDARD 2017 Charpter two : General Understandings and Defaults

 

Bypass rule: If a player bypasses a natural notrump bid to make a nonforcing bid, then later bids notrump uninvited over an opposing bid, that notrump bid is unusual (showing additional distribution, not offering to play in notrump).

Conversions: When either a double or a notrump bid, when followed by a conversion, would show length in the same two suits: starting with a double suggests more in high cards, starting with a notrump bid suggests more in shape.

 

 

I dont understand those words meaning , please help me thx. give me some example better.

The first one refers to auctions like

(1♣)-pass-(1♠)-2♦

(pass)-pass-(2♠)-2NT*

 

Here, the initial 2♦ bid is nonforcing and bypasses the natural 1NT bid. Hence, 2NT is not natural but shows four hearts and long diamonds.

 

The second one:

 

(4♠)-dbl_or_4NT-(pass)-5♣

(pass)-5♦

 

Here, starting with 4NT would show a more distributional hand, starting with double would suggest more points (maybe the latter inference isn't really applically in this auction, anyway that's the general idea of the conversion rule).
