Nice try, but you have played 6 trumps from hand (3 diamond ruffs and 3 trump entries to dummy).
There seem to be three main lines.
1. Dummy reversal + 3 heart tricks
2. Dummy reversal + 3 club tricks
3. 3 heart tricks + minor suit squeeze
Lines 1 and 2 both need the SJ onside and seem to go:
Ruff the lead in hand
Spade to the ace
Ruff a diamond
Spade to the 10
Ruff a diamond (high)
{cash one or more hearts}
Club to dummy
Draw the last trump
{set up side suit}
The problem with these lines is that we can't cash the ace of diamonds before losing a heart/club trick because otherwise they might have a diamond to take, but alternatively we risk never being able to take it. This means we need either diamonds 4-4, or the hand we lose a club/diamond to, to have no more diamonds.
If we lose a club/heart earlier to a 5-card diamond suit we can find the ace of diamonds ruffed off.
Which rounded suit to play on?
Clubs needs the suit 3-3 or two honours doubleton
Hearts there are various holdings we can pick up: we can't take two finesses against H9x(x) onside because of lack of entries, so we are left with 3-3 or Hx offside (or alternatively 3-3 or 9x offside but that is less likely). I think that makes hearts better but I haven't worked it out.
We need spades 3-2 with the jack onside
We need our side suit to play for 3 tricks
We need diamonds 4-4, or 5-3 with the shortage winning the club/heart trick
------------------------------------------------------------
How about the alternative squeeze line?
Assuming from the lead that the DQ is on our left, we can play:
Win the diamond lead (not ruffing it as we want all our trumps)
Cash the AK of hearts (we'll come back to this later)
Assuming an honour hasn't fallen on our left, play a third heart. Assume the last heart is now a winner.
A club return is worst. Win in hand. Draw trumps, including picking up singleton Jack and Jxxx on our right {get back to hand with a diamond ruff if necessary to draw the last trump}
Cash winners
Coming down to a 4 card ending with DJx and A9 of clubs on the table, a master heart and 3 clubs in hand, on this heart we throw a diamond from dummy and if LHO had four clubs originally he is squeezed.
If LHO plays an honour on the second round of hearts I think we draw one round of trumps in dummy before playing a third heart (if RHO rises and plays another heart we will over-ruff in dummy if necessary; if RHO doesn't rise the heart gets ruffed on our left but now trumps are 3-2 and we can manouvre a heart ruff anyway, we can still pick up 4-1 trumps)
This line needs hearts playing for 3 tricks (as do the lines above), and also needs LHO to have 4 (or 5) clubs, but picks up all 3-2 spade breaks plus a little over half of the 4-1s.
There are various alternative possible lines in hearts, but overall I think this is a better line. I need to think longer about the best line in the heart suit.
Win the ace of diamonds
