FM Steve Stoyko gave a wonderful lecture on Bishop Endings at the Kenilworth Chess Club on Thursday, September 22nd, which I have finally written up based on my notes (with additional analysis). His focus was bishops of the same color, where the superior side often has winning chances. Though Steve would have liked to have given dozens of other examples, I think the ones he focused on went very far in laying out the principles. I have chosen to focus on only about half of the examples Steve presented, organizing them according to several critical themes: exploiting the short diagonal, needing "two weaknesses" to win, using the more active king, fixing targets on both sides of the board, deflection, and zugzwang. For those who want even more examples, I have compiled a bibliography of sources, including multiple videos.
Though Steve discussed several pure B v B+P endings, I have chosen to focus only on the classic position analyzed by Nimzovich since all of these endings have been well covered in several YouTube videos (see above). Pure B v B+P endings are fascinating, but they are nowhere near as stunning as the themes Steve covered in Bishop endings with multiple pawns where one side has a positional advantage. Here the theme of "two weaknesses" (typically two pawns on the same color as the Bishops, which can become targets) is very much worth remembering as it occurs frequently in practical play. In all of the positions, an untrained player could easily agree to a draw without recognizing the winning advantage that one side holds. Meanwhile, a player who knows how to fix his opponent's pawns on the right color square can steer the game toward a winning Bishop ending.
I look forward to Steve's next lecture, when he promises to do something on Rook endings.
