Leads after a Splinter bid by Matthias Huberschwiller

A: ♥6 - Dummy will have at least four Spades, leading a trump won't prevent ruffs, but could lose a tempo to set up tricks.

With honors in Clubs, there won't be immediate discards, so an active Diamond lead isn't needed. Lead a Heart.

Your result so far:

A: ♣2 - This time, when declarer will take out your Ace of Diamonds, he might have discards for his losers.

Therefore, you need to make and attacking lead, to set up tricks as quickly as possible.

Your result so far:

A: ♥3 - Dummy has a 5-card Diamond suit (rarely 4), with a Spade fit, and a strong hand. You need to set up quick tricks by leading a Heart, even with a bad K-J tenace.

It's unlikely to blow up a trick, since points will be in dummy's hand, and could set up tricks before they could be discarded.

Your result so far:

A: ♠6 - This time you have five cards in dummy's five card suit. Declarer will probably go for a cross-ruff, since he can't set up the Hearts.

To prevent him from doing that, a Spade lead will work well.

Your result so far:

A: ♥A - With those poor Diamonds, there is a huge risk of declarer discarding losers from dummy on his Diamonds.

Leading a trump won't help, you need to cash your tricks. But which Ace to lead? Hearts, since you are less likely to blow up a trick, to preserve the Club tenace.

Your result so far:
