Easy, but not for me. A practical chess puzzle

Somehow, won the Team Ukraine's Friday Tournament #8 "New Year 2020" (2+1 bullet Arena).

 But pity that, in the position on the diagram, I didn't find a way to refute Black's opening concept entirely.

White to play. (+-)

For the record, the game, @Mikhail_Golubev vs @simpotxa777 is here: https://www.chess.com/live/game/4363437496
