Acol Bidding
Open your longest suit 1D. Partner responds spades and you bid 2C showing a hand containing 5 diamonds, 4 clubs and less than 17 HCP. you could respond 2NT showing 15-16 HCP but its tricky with your spade singleton.
Plan Before You Play
Dummy goes down in Suit contracts Count your losing tricks. Spades:0, Hearts:1, Diamonds:0, Clubs:3. Looks like you'll make your contract.
The Play
The unbid suit, a heart is led, the 10H or 9H in dummy draws the AH. When you get a heart return play JH in the hope that east's takeout double means he's got the QH as well. Lead a low club to the 10C, taken by east who returns the QH which you cover but west ruffs with the QC. Win the spade return and play a second round of trumps which east wins with 9C, only the AC out now so let's just ignore it and let east ruff where he can. Play KS and QS and go to ruff a 3rd spade but east uses his last trump, the rest of the tricks are yours. Makes 8 tricks
Comment
Easts double indicates that they have points - if any finesses are needed you should be playing for east to hold the honor cards. Usually you'd want to be in NoTrumps with minor suit fits but sometimes its just too dangerous.
The above commentary is intended as a guideline only. As with any Bridge hand there are many ways to bid and play any hand.
