Bidding at Duplicate - from Tournament #274, Board 16

by Mixalias

Aggressive bidding is what makes duplicate fun, most hands are slightly overbid, and the hands played aggressively (there is very little of the annoying bagging game). However, there is a difference between slightly overbidding, and overbidding too much as this hand shows.

First of all, look at the North hand. At regular spades, this is clearly a 3 bid, a 4 bid would be too high. At duplicate a 4 bid may also be appropriate - as two North players actually bid.

On table 1, East bid nil and made it (this was the wrong bid, the nil should have been easily set - all North had to do was overtake K with the A at trick 12 for the double set). However, in this case partner bid 5 with the West hand - and got set. This is clearly an overbid, for two reasons. The Kxxx is bid for 2, and Kx is bid for 1; these are both pushing the envelope a bit, therefore bidding the AQxxx for 2 is too much. Finally, when defending a nil, this should be a 4 bid anyway.

On table 2, East bid 2 and got set, taking the 0%. Here the clear principle of "with only 2 spades bid conservatively" was violated, and E/W dearly paid for overbidding. Although 2 tricks do look possible with the East hand, whenever you have only 2 spades, bid conservatively (if nothing else to protect partner). Thus a bid of 1 is clearly called for (as the other three East's properly bid).

On tables 3, 4 and 5, East correctly bid 1. However, look at table 5, there West only bid 3! For such cowardly underbidding at duplicate, the E/W took a deservedly low score of 26%.

Table North East South West N/S Score N/S Result E/W Score E/W Result
#1 4 nil 4 5 129 100% 50 87%
#2 3 2 3 4 118 75% -60 0%
#3 4 1 3 4 70 50% 49 50%
#4 3 1 4 4 69 12% 50 88%
#5 3 1 4 3 69 12% 39 26%

One could argue that N/S at Table #2 underbid, however since they did set their opponents, they got a 75% score. This brings up a very interesting question. In normal spades at 4th hand we reduce our bid to avoid a 13 bid. Did N/S do this at Table 2? If so, is this the right strategy for duplicate, or should we be less afraid of 13 bids at duplicate?

Finally when you do come join us, take to heart this lesson about duplicate: be aggressive and overbid a little, but don't overdo it and overbid so much you get set.
