T1: I figure I should play low from dummy. If heart KJ are split, I'm looking at 3 heart tricks if RHO puts in the honor. If this pans out (or if hearts are 3-3), I'm looking at 1 spade, 3 hearts, 1 diamond, and 2 clubs, so I'll have to manufacture 2 more. The club hook may provide an 8th, and opps may be endplayed into leading spades or (more likely) diamonds. When I see the H9, I strongly suspect that I have 3 tricks.
T2: I can get started on my spades, but even if I establish them, my only sure entry is in hearts, and I only have one, so I feel like this can only go poorly for me. I felt like it was better at this point to try to take the club hook, so I played a low heart and inserted the 10, which held.
T3: Club hook held. Now I've got 1 + 3 + 1 + 3, so I only need to establish 1.
T4: Club ace. Looks safe enough, though my spots aren't good enough to withstand it if clubs break poorly and the long clubs have some entries. But I did this in case I needed it to extract a safe exit in case clubs were 5-2.
T5: Heart up. If they are breaking, I'm home. They don't. RHO suggests that he has the ♦K. So now I'm thinking endplay.
T6: I didn't want to lead the 4th heart because I wanted RHO on lead. So I played a spade toward the K (if LHO has the spade ace, he'll get in to lead the diamond thru anyway). LHO won the ace.
T7: Heart, RHO pitches a club, which I thought was strange. In hindsight, should this suggest Jx of spades? I pitched a diamond from hand. Is this right? It felt like I might need to pitch a club and save the diamond, but it's possible that clubs were 4-3, and now my clubs are cashing. Oh, but I only need to establish one club anyway, so it can't hurt (beyond blowing an overtrick) to pitch the club.
T8: Diamond jack. Beautiful card. Now I'm home.
Thoughts? TIA.
