Cross IMPs. Pd and opponents are GIB.

Lead=♠Q (100 % singleton according to your experience with this piece of ***** EW players)

Thank you, Mr Ace for all your fascinating insights into Gib's style of play, My guess

Spoiler

Try to elope with all your trumps

• ♠. ♦K. ♣K. ♦A. Ruff a ♦ (assume ♦Q does not appear).
• ♥A. Ruff a ♦ (hoping RHO has 4♦s).
• ♣A. ♥K, ruff a ♥..

Think again. Your line requires RHO to hold 4 diamonds. You can do better than that.

Best chance I can see is the partial elimination and endplay aiming to score the 10th trick with ♠J8 under ♠KT9. That is probably an improvement on the full dummy reversal but there is almost certainly something better, particularly against stronger defenders.

after you ruff a diamond in dummy, you have to decide which other red card to ruff in dummy. of course you expect this to be a heart, but it gives an opportunity for a great false card from west when he throws his queen from 4, setting up your essentially worthless jack, so that you'll play a 4th round and allow east to reduce his trumps (yes i know hearts are probably not 6-2 after west didn't open a weak 2, but you do have akj between the 2 hands, so it's definitely possible).

Playing East for 4 diamonds is unlikely, when spades are 1-4 already.
The hand can be made if East has 4333 4432 or 4342.

Duck the ♠Q. West could be endplyed at trick 2. He might even switch to clubs.
But for the sake of the argument let's assume he switches to a heart and the ♥J does not hold.
Play hearts and ruff the third heart.
Now play 3 rounds of diamonds and ruff the third diamond.

Now play 3 rounds of clubs.
If East wins he is trump endplayed.
If East ruffs he is ruffing your club loser.
If West wins, East will have to ruff the next card on which South will play the ♦J and West is trump endplayed.

Better to cater for East being 4♠333.

If E is 4333 it is easy. Just ruff a diamond and a heart and cash ♣ AK and exit with something other than trump club and claim.

This way we always make as long as East has 3-3 reds or more. I made a mistake in last 4 cards and exitted with diamond but still prevailed. I should have exit with club. So i can make when E has

4333
4342
4432

When he is 4234 I fail.

East holding 4th diamond won't help him if he throws ♦Q as long as club QJ are split.

So I won the ♠ A and played 3 rounds of diamonds, ruffing 3rd. and then AK of hearts and a heart ruff, now club K and club to A. Exitted with last diamond. If RHO has 4th diamond, I ruff for 10th trick. If LHO has it, which he did, I discarded a club. But RHO had QJx clubs and I prevailed despite my mistake. He could not ruff 4th diamond and play a club to his pd.

My mistake was to exit with diamond in last 4 cards. If I exit with clubs I always make. (after 3rd ♥ is followed)

my point was that if east has 4D and 2H, you need to ruff 2 diamonds, then play the clubs. you play 3 rounds of diamonds then decide which red card to ruff next. if west plays the queen on the 3rd round you'll be tempted to ruff/cash the 4th diamond. if west then magically produces the 4th diamond, it'll be too late to reverse the decision if east can safely exit in clubs.

I understood you.

But what you saying is almost impossible. Assume I played 3rd ♥ and got overruffed.. In order for me to lose

-East will hold 3d+2h+4club
-W will drop the Q from 4th
-East with 4 clubs will have no club honor.
- W would be leading trump Q when he has a QJx suit

I would not really worry about this.

Your second scenario, when E has 4 diamonds 4243 but over ruffs 3rd ♥, I may still make it. (if i start hearts before ruffing diamonds and if diamond finesse works when ruffing 3rd ♥ fails) Assume that I ruffed 3rd ♥ and east followed and then ruffed 3rd diamond but it is over ruffed (this is more likely). Now east will need a safe exit, which is unlikely unless he has 4th ♥

A similar line seems to work when RHO has has a singleton ♣
