1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. f3g5 From time to time, white players spice things up with this old and dangerous knight move, making the game much more fun than the slower positions after 4.d3. 4... d7d5  5. e4d5  5... c6a5 This move is more or less automatic in classical elite games, but if you're looking for some fun in your blitz games, you might want to investigate the moves 5...b5 or 5...Nd4. 6. c4b5  6... c7c6  7. d5c6  7... b7c6  8. b5d3  8... f6d5  9. h2h4 Much less common than 9.Nf3, but as it was played by Firouzja in a classical game recently, I imagine Ju knew it. 9... d8c7 One of several promising possibilities for Black. 10. b2b3 A new move that was played quickly by White. 10... h7h6 Removing the knight from its dangerous position on g5 is the most natural option. 11. g5e4  11... f7f5 Black continues chasing the knight. There are other interesting options. 12. e4c3  12... d5f6  13. c1b2  13... f8d6 Praggnanandhaa said he felt this move was inaccurate.
