This is the deal in our weekly online training on 12th Feb, 2018.
It seems to a normal game contract in the early stage, however it is quite intriguing in the endplay.

The leading reliefs you. If the distribution of club is normal, the contract looks safe now. You could win 2♠, 2♡, 1♢ and 4♣. You win with the ♡T and drive out ♣K at once. East plays a small ♢ after winning with the ♣K. You win with the ♢K in hand. It is obvious that East holds ♢A, which gives you a chance for an overtrick. If East holds 6♠ and ♢A, he will be squeezed in the endplay. When you draw ♡A and all the ♣, remaining 5 cards, East must keep 3♠ and 2♢ with A. And now he will be throw-in. If East holds 5♠ with Q and forgets to unblock the ♠Q, he could not escape from being strip squeezed at last. You draw ♡A first and East follows a small ♠. When you are sticking to your plan, West discards ♢T unexpectedly. So there are two possibilities now. West keeps 2♠, 2♡ and 1♢ or 3♠ and 2♡. In the first situation, East will be strip squeezed unilaterally. In the second situation, whatever who wins the third ♠, East or West, he will be thrown-in.
Although the overtrick seems not to be important in a whole game, sometimes it plays a significant role in a knock out tournament.
