Opening 1NT, natural overcall

East’s overcall of 2 promises no more than a decent five-card suit - there is no need for the 5-4 shape so revered by some.  West might be tempted to raise on his nine points and four-card support.  On the other hand, East is limited by his failure to double and NS don’t appear to be going anywhere so pass should be sufficient.  He might well raise in a competitive auction.

Evaluation


Somehow our opponents made only eight tricks in spades.  It will make nine more often than not.

Meanwhile NS will do well to make more than 6 tricks in no trumps, but might scrape home in a heart contract thanks to the lie of the club suit.

An EW spade contract is the winning choice.

Beginner and above

Opening 1NT, transfer overcall

Because the sequence can be completed at the two-level East might choose to transfer into his four-card diamond suit and follow with a rebid of his five-card spade suit.

N/S may put up a barrage in hearts but EW will usually still finish in a spade contract.

If North pushes to 3 West will consider a double.
