Design for Bidding is a book by the Russian-born English bridge player S. J.

[1] It is about the theory of bidding in contract bridge, particularly in the context of the Acol system of which Simon was one of the co-developers.

It was the first, and as of 2015[update], remains one of the few, studies of the thought processes involved in designing a bidding system, rather than simply setting out the author's conclusions.

"[3] Design For Bidding "remains wonderful reading, because Simon argues persuasively for the Acol state of mind style of bidding.

In it, Simon sets out what he calls the "deciding factors" to be assessed before adopting a specialised meaning for a bid:[1]: 48–49 Part I concludes with Simon's description of Acol as "not so much a system as an attitude of mind".
