Most 1200 CCRL rated engines would have never blundered.

The blunder that helped the American born Mishra, Abhimanyu from Indian Parents to become the youngest GM in History, White should have played Kd5!, but blundered and played Ke5? I know that they were playing with only a few seconds left on their clock, but that is what makes engines even low rated so special, you can give any 1200 rated engine 10 seconds left and it will NOT blunder.

White could had won if GM Leon played b4 instead of blundering like he did to move his King to e5?
