Leads against a suit contract after competitive bidding by Matthias Huberschwiller

A: ♠Q – The lead of a doubleton in partner’s five-card suit (at least) is often good because it can permit both: to establish his suit and/ or a ruff for you.
With a doubleton, you need to lead the higher card first, like this partner knows that you’ll be able to ruff.


Your result so far:

A: ♣6 – Despite partner’s bid, the lead of a singleton with the plan to get some tricks from ruffing is always a priority.

Your result so far:

A: ♦Q – It is true; your partner did bid spades. But this does not allow you to either lead or underlead an Ace, which is the most dangerous lead against a suit contract. (South could have the Spade King.)
Therefore, you need to lead high from your sequence in Diamonds.


Your result so far:

A: ♦7 – The fact that you bid your Spades does not change the priority of the possible leads. Leading your singleton Diamond is still excellent!

Your result so far:

A: ♠6 – A lead from your small cards in partner’s suit is preferable compared to your sequence in Clubs.
Leading a small card would promise an honour, and the seven could lead partner to think that you have a doubleton.
Therefore, you need to lead the six and next play the seven in order to show that you started with three small cards.


Your result so far:
