Well played, but not well enough

There is a saying in chess. When you find a good move, do not stop, look for a better one. The same is true at matchpoints. In the following hand, I, abhirar, got a 77% score making two overtricks in 3NT. The first few tricks have possible different plans, but let me pass over them without too much comment. Trick one, H6, 9, J, A Trick 2: Spade 5, HEART DEUCE, SA, S2. Trick 3,4 test clubs, on T4 RHO pitches D9 and I keep the remaining clubs for transportation. Trick 5: I play the SQ to drive out the SK Trick 6 (At this point all returns give me at least 11 tricks which the reader can work out) RHO returns ST to drive out my SJ I win and Trick 7, from my S equals 8,7, lead the 7 to drive out HIS S9, but defence makes its first matchpoint mistake ducking this trick. Now I can take ALL the remaining tricks making 12 instead of 11 (a MP score of 89% instead of 78%), can you see how? This is the ending Dummy S:void H:KT D:AQx C:x LHO S:void H:Q87 D:x C:xx RHO S:96 H:none D:KJ82 C:none Me: S:8 H:x D:Tx C:QJ Well the only line to win all the tricks is to finesse the HT, cash the HK pitching my diamond, Cross to the Club master, cash the last club master pitching a diamond, and RHO is simple squeezed. If the S8 is not high in the two card ending, the DAQ should score two tricks.
