It's hard to beat a grandmaster.   They know so many offensive and defensive variations.   Congratulations to your student and to you for your good teaching.

congrats to the student and the teacher!  these sweet moments don't come very often for either.  well done to both.

Wow, this is very impressive, congratulations to you and your student

He could have used engine

Is this his own notes ?

congrats! I've beaten a couple GMs, but never one above 2500, I've had my chances (I think I threw 3 or 4 different games), so I know how big of an achievement that is. I don't think you mentioned how did his tournament go, how much rating did he gain?

Also, why does your student start with 2...g6? Since you play Kalashnikov you can show him Rossolimo, which is the only drawback of 2...Nc6 to my knowledge (and 3.b4, but like cmon), while 2...g6 allows 3.c3, 3.d4 with Qd4 and 3.Bc4 with c3 plan, all of them scary. Also delayed smith-morra if he doesnt play g6 against that. I started learning the Accelerated dragon recently and 2...Nc6 seems like much better choice. Did you discuss this with him?

how did you recover the game if it's not dgt board?
