Your thoughts before leading a diamond
------------------------------------------------
- Partner must have a side suit, so go to the 5-level at red but not have enough stuff to double 6H.
OK, opps have a lot of
♥ so partner is likely to have 51(43) or 5044. This means that opps have (6)7-8 cards in each minor. No indication of a timing problem.

Partner is hugely likely to have 5 spades (for the same reason), so a spade lead will probably be ruffed.
When will a
♠ lead cost a trick or 2?
Assuming that partner has 5
♠, the remaining 2 can be 1-1 or 2-0.
If they are 1-1 we can not lose a trick in
♠ and playing
♠ now may be the only chance to get a
♠ trick at all.
If the
♠ are 2-0 we can't lose a
♠ trick, because we never had one. But we can lose a side card trick, if the 2 missing
♠ cards are AQ and opps can dump 1-2 loser, but this is very unlikely.
So a
♠ lead is quite save.

- If partner has a diamond suit, we might need to cash the AK now, before declarer draws trumps and runs clubs.
How likely is partner ho have the
♦A?
He has got 5 of 7 missing
♠ so there is a 5/7 (71%) chance that he has the
♠A. If he has the
♠A:
- the chances that he also has the
♠Q are 4/6.
- opps have bid to 6
♥ with only 25-27 hcp and you still have to subtract any other honor in partners hand.
So it's unlikely that he has side honors and if he has, they will be badly placed.
If partner does not have the
♠A he will usually have the
♠Q. This means that opps have bid slam on 29(-31) hcp minus what partner holds in the side suits.
So it is still unlikely that he has side honors.
So leading under the K will more often cost a trick than gain one.

- But if partner has clubs, the diamond lead may not cost, as declarer is likely to have the ace and we may well make a diamond trick anyway.
If partner has a
♣ honor this will almost always cost a trick.
