East is dealer, nobody vulnerable.

Table 2:

At the table 1, south played 3NT after showing minors over the weak 2, and not willing to let partner play 3♥, tried a thing game.
♠K was led, taken, now declarer tried to stablish hearts playing low to 10, expeting to endplay east on his way to dummy later.
East won ♥Q and escaped with low diamond. Declarer though east would never escape underleading ♦AQ, and now his best hope was to catch stiff ♦Q to save some undertricks, so he tried the King. Not a success, he also made the mistake of pitching a club on the run of the spades and defence then made 3 club tricks after west crossed the suit. He was held to 2 tricks and 7 downs.
At the table 2, north was (very) agressive and became declarer in 4♥, received the ♠6 lead to the ace, king and 2, and played a heart to the ♥10 captured by ♥Q. East switched to low diamond, declarer guessing to play low and ♦A won. Now west, eager to get his his diamond ruff setting the contract, played ♠3 to force partner to ruff this trick. Partner ruffed, but took ♠3 a suit preference for clubs, and switched to ♣10. Declarer won ♣Q.
This only set 9 tricks to declarer, but after drawing trumps, declarer ruffed a club in hand to eliminate west's clubs, then squeezed east in the minors for the 10th trick.
So we made 2 tricks in one table, 10 by the opponents in the other *8 trick difference). Adding 350 to 420 for a way to lose 13 IMPs that you probably haven't seen before.
Bonus question: wich of the players was me?
