| May 11, 2019 at 12:30 | comment | added | user1583209 | @Baldrick: Exactly and white's dark-squared bishop can easily take care of the dark squares... For instance attacking the pawns on a7, c7 will be quite annoying for black as he'd either have to defend them (binding a rook to defense) or move them to light squares such as a6 and c6, where they'd hinder the movement of the black bishop. | |
| May 11, 2019 at 12:28 | comment | added | Baldrick | @user1583209: Ah, I see. Thanks very much. So.. that's the reason for the final move. You've got rid of the dark squared bishop, so you build a nice light squared pawn chain that is hard to attack / penetrate by the remaining bishop, and covers a lot of squares on the kingside that black might want to attack. | |
| May 11, 2019 at 12:26 | comment | added | user1583209 | @Baldrick: Regarding your second question. As above, the white pawns (e4, f3) are limiting the squares available to the light squared bishop. | |
| May 11, 2019 at 12:25 | comment | added | user1583209 | @Baldrick Generally, in open postions bishops are stronger than knights. The dark squared bishop is particularly strong here because white's most relevant pawn (e4) is covering light squares, and the dark squares are relatively weak. That's why it is advantageous to trade the knight for the bishop. | |
| May 11, 2019 at 12:20 | comment | added | user1583209 | @David Bg5 looks good as well. To me mostly a question of personal preference. Keeping the bishop has the advantage that you can attack the black queenside pawns easily. | |
| May 11, 2019 at 12:17 | comment | added | Baldrick | Thanks for the answer. Very instructive. Can you explain why, given the black pawn structure, their dark squared bishop is stronger than a knight, and therefore worth an exchange? And also your final comment - I can see the first two points, but why is my bishop better than his in the end state you show above? | |
| May 11, 2019 at 12:10 | comment | added | David | I'd say 12.Bg5 is stronger than 12.f3, as we protect the e4 pawn, we continue development and avoid any kind of opposite-bishop draw chances | |
