I object to the problem. Two declarer play errors have already been made, both of which have greatly reduced the chances for bringing this contract home:
1. You should not win the opening lead, but rather the second round of spades. (Squeeze possibilities no longer exist when you win the first spade.)
2. The first round of trump should be won with the Queen or Ten, not the Ace or any high trump in the Dummy. (You need trump entries to Dummy should clubs break 4-0; there are no problems with a 3-1 or 2-2 trump split.)
On what layout of the opponent's cards do you see the recommended line of play failing?
Spade Ace
Club Ace.
Small spade.
This goes down how? He can make the same play if everyone follows to the first round of clubs.
Declarer plans to take two spade ruffs in the South hand, four club tricks in the North the master hand after the ruffs). That's six tricks. The spade Ace, the two diamonds, and the three hearts come to six more. That's twelve. No squeeze, no finesse, no nothing, just don't block the clubs.
OP mentioned that he put his contract in (some but not great) danger by playing on some red cards before setting up for the ruffs. True enough. So that was the point. And yes, there are some transportation issues. With the clubs 4-0, the club seven is valuable to eliminate the need of using any red cards back and forth. With care, declarer leads no red card until trump are out, unless at trick 4 a club is returned Then declarer needs to play a red card once himself. After spade ace, club ace, small spade, and then any return that is not ruffed the hand can be claimed.Or rather if when the club is returned at T4, win in North hand, ruff a slade high, come to hand with a heart and when that is not ruffed then claim. Basically, after three tricks, you can claim, as was said, unless there is a first round red suit ruff available.
