Pff we should play safe play to protact from 5-1 D? What?
i mean i get the idea but this examble is completely wrong!
5-1 D was close 7,8% so i "gain" 7,8 % from 5-1 D but i lose 32!% just because i need 3-2 S!(i mean if D was 4-2 no matter s we win)

Ok i love the idea from safe play i get the point but sould removed from other one correct examble

It looks correct to me. If diamonds are 3-3 or 4-2, you don't need spades to be 3-2. Playing the suggested way allows you to make whenever possible.

LOL i just miscount the D from over one year!
if D was 4-2 on 2nd round of D we have 2 left, so even if return s, i need only 2 more ruff of D

I just saw always the final D dut i never minus this one from 5th round!(discard 9h)

So i have gain the change from 1-5 from East(7,27%) only if s was 3-2(67,83) so i gain 4,93% Tnx Sfi from the help

If diamonds are 4-2 ducking the second round sees us home. We only need 1 ruff to set up the suit (or on a side-suit return we have a high cross-ruff)


The advantage of the duck over playing AD seems quite marginal, roughly 7.5% (half of 5-1 breaks. These problems are very much aimed at IMPs play. At pairs we bang down the Ace and try for an overtrick.
