If I made promises to my dad but they came true after his death, does it still count?

Honestly I was just doing it for him. I've just recently finished the project he started long ago. It has done to the editorial section and been approved. I've also promised to beat a good chess player he couldn't with the condition that I'll just do it for him that one time only (I don't care about competiting, never did) and not come out in public. After winning 1-0 and 3 ties, that was enough for me. However, my dad never got to see fullfilling my promises. He died two days before the game and I already pay the entry fee and the project was already in the finishing process by then.

Though I don't know if that's even worth. That was all for him. The money I won in that brief competition was for him too. I did it for him. I wanted to make him happy with what he couldn't finish. That would've been his money and his approved project.

Does it still count? Is it worth it?

I've promised to do that for him, that he'll get to see me fullfill them... he never did. He died before they came true. That was all for him, not me.
It sucks that his project took too long to get approved and he never got to know that. Sucks that he never got to know I beat his chess rival once.

Truth be told, that was a narrow and lucky won after 3 consecutive ties. Had I continued playing longer, I would've lost by then. I thought that was enough and like stated, it was just for dad.
