I dont think, it was nessesary to go broke in this hand. 20BB is quite a lot to open jam, and if you make a standard 2,2-2,5BB raise, you can check back flop, call turn if he even bet with this hand, and fold river to still survive in the tournament. Its a bad call by him for sure, but he probably had at least 35% equity, so this will happen fairly often. After all he only needed a pair to beat your A high.
