Example of ‘winning’ even when
going down
Consider opponents are vulnerable and you are
NOT vulnerable
They bid 4H, if they make it they get 620
Instead you bid 5clubs you lose less than 620
points if you are
NVul, not doubled down by 12 (600 points to opponents)
Vul, not doubled down by 6 (600 points to opponents)
Nvul, doubled down by 3 (500 points to opponents)
Vul, doubled down by 2 (500 points to opponents)
For all of the above you have given away less
points and you may force the opponents to next
level bid!!!
