Don’t Double Two-Level Contracts for Penalty
It’s risky business to double two-level contracts for penalty. I don’t recommend it, and I don’t do it. Too many things can go wrong.
1. If they make a doubled two of a major (non-vulnerable), they will
score 470 points. If you set the contract 1, you’ll only get 100
points.
2. You have to take 6+ tricks to their 8 tricks, and partner might not
follow your line of defense.
3. Your partner may miss the point by pulling the double with a bid.
4. The declarer might have a two-suited hand, and your pair will
have aces and kings ruffed out.
5. The partner of the doubled player might pull the double by
switching to a makeable contract.
6. If your pair is vulnerable and their pair is not, you may miss a
600+ game for a 100, 300 or 500 point set.

Too Many Other Reasons to Double at the Two-Level (continued)

4. 1 diam dbl 1 NT pass 2 clubs dbl Repeat TKO
5. 1 spade 2 clubs dbl Negative Dbl
6. 1 spade dbl 2 diam dbl Negative Dbl
7 1 club pass 1 heart 2 diams dbl Support Dbl
When in Doubt
If your partner doubles a two-level contract and you don’t know what
partner’s double is telling you, remember:
He/she isn’t doubling for penalty.
Find a bid somewhere.
Three-Level Doubles
If the opponents as a pair have only bid once each, treat partner’s double as takeout. That would be preemptive bids or limit raises. However, if either opponent has bid twice, treat partner’s double as penalty.
Final Words
If all your penalty doubles work, you’re not doubling enough. Good player’s penalty doubles fail about 1 out of 3 or 4 times. That’s 67% or 75% success.
