What do you think of this sacrafice?

Black by all means did not accurately defend this attack, but could he have?

Do you think the sac is solid and decisive? Do you think the sac is a blunder? Do you think the sac is not decisive and black can still fight, but white is not worse off?

The sacrifice leads to interesting play, where white should have compensation for the sacrificed material after 9.Rd1. 7.Qf3 however, was not a good move since black could play 7...Ne5 and white has to part with the bishop pair. Normal development with 7.Nc3 would have maintained a stable edge.

Slightly risky, but you have two pieces attacking and another soon comming, it is discusible instead of Nx he could've played Ne5. Certainly was not great oponent so any move was probably good.
