The Herbert Negative is a conventional response to show a weak hand after partner advertises strength. Responder makes the cheapest step response, typically with 0-7 points, as an artificial "negative."
The eponymous convention was invented by expert Walter Herbert (1902-1975), who was a member of the Austrian team that won the 1937 World Bridge Team Championship.

In the Austrians' Vienna System, an artificial
1 opening showed 11-17 points. (An artificial 1NT opening promised 18+.) In response to
1, 1 was the Herbert Negative that indicated 0-7 points.
While the Vienna System has not survived the ensuing decades of modern bidding theory, the principle of the Herbert Negative lives on. A few examples are below.
Strong 1 Opening Bid
In strong club systems like Precision, a
1 response shows 0-7 points. This is a classic derivative of the Herbert Negative convention, although the eponym has faded over time.
Strong 2 Opening Bid
The strong 2
opening bid, a staple of Standard American bidding, uses a
2 negative response showing 0-7 points. (It can also show a hand with 8+ points and no other suitable reply.)
ACOL Two Bids
The Herbert Negative can also be used in response to an
ACOL Two Bid. The cheapest step response by responder is artificial, showing 0-7 points without support for opener's suit. Examples:
Opener's rebids are natural.
