Chessodoro game review. 15+10 game on chess-com between approx 1500 rated players, student plays black.

Conclusions
1.opening white played not so good 4.c3 they mix up with french, 8..Bb4 was dubious, but you gained edge and won d4
2. 13...a6 nice intermezzo
3. solved the K safety issue and started converting pawn up
4. managed to exchange Qs and got totally winning rook endgame 2 pawns up, but low on time
5. activation of rook was a key pattern in this game, don't be passive with Rb8 activate from behind
6. missed the win precisely of not activating the rook. Key takeaway - practical conversion in rook endgames is to keep the Rook active, then the King and finally pawn quality.
