The opener's sputnik double.
After his partner's response at the one level, the double is part of the sputnik family and shows:
  • a strong opening hand
  • three cards in the responder's major.

The redouble after the responder's sputnik double means the same if the opponents have a fit.

Problem E6449 The opener's first double is a sputnik double because the opponents have a fit.
 
 
The opener's penalty double.
The opener's double is a penalty double when the bidding sequence clearly shows that their side has point majority and that the foolhardy opponents should be punished. This is the case when:
  • - the responder changed suit 2 over 1
  • - the responder redoubled. (10+HCP)

If his Partner makes a sputnik double and the opponents don't have a fit, the double is a penalty double (but if they have a fit it is a takeout double)
