At 3:15 after 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 Bb4+ 5. Nc3 dxc4 6. Bg2 O-O 7. O-O Nc6 8. a3 better was ...Be7 instead of 8...Bxc3 9. bxc3, and here 9...Rb8 intending 10...b5 was still OK for Black.
Why did he take the black bishop ? He was supposed to push his pawn to threaten the black bishop instead because he still had the white queen and white rook forked... smh
Doesn't Black wins the quality (14:30) after B x Na5, with the answer B x Rb1? After that a lot of pieces can be exchanged but Black still keeps the quality of a Bishop against a Rook.
