The first thing I do is ask, what trumps are outstanding. They are 9873. That means I can draw them with four leads, but need to be careful about low trumps being overruffed.
The second thing I do is ask, which honors are outstanding. They are: QJ of spades, AKQ of diamonds, and Q of clubs. My AK opposite a doubleton takes care of the spades. I can trump the diamonds. My main worry, ironically, is the Q of clubs. But if that's my ONLY loss, I make six.
Here's how: 1) Ruff the diamond lead. 2 Draw all four trumps with AKQJ, discarding the diamond from dummy. You have one trump left in hand. 3) Take AK of clubs. 4) Lead J of clubs. If the queen hasn't dropped already, someone will take it. You have made seven tricks, lost one, have five more to go.
Opponents are out of trumps because you've drawn them. Realize that they only have four clubs between them, because you have nine. If they lead their last club, capture it with the 10 in dummy. Play AK of spades, ruff a spade in hand, then win the last club (five tricks). If they lead a diamond, ruff in hand, discarding the T of clubs from dummy. Lead the last two clubs (from hand), then cross over to the AK of spades (five tricks). If they lead spades, win the AK of spades. Win the T of clubs, then cross to hand with a spade ruff, and win the last club (five tricks).
Note how I counted trumps, clubs, tricks, honors, etc. This process is at least as important as winning the hand.
