Support Doubles

<BODY> <H1>"Support doubles</H1> <P>Here is the <A href="SupportDoubles_main.htm"> non-frame based version of the Support doubles convention</A>. The support double applies when you open, partner responds in a major and the RHO overcalls at the two level. Double shows three card support for partner's major and a raise would show four card support. </P> </BODY>
