Prof Dragon Teaching the Opposition to Some of you.............

[Chessqueen]

I am posting to you game #19, which is a great example of how to play the Opposition, Watch the last 100 moves where Komodo Dragon can teach some of you how to draw by holding the Opposition great endgame technique, even by losing to Koivisto with a Bishop + pawn, but Koivisto Bishop was the wrong color Bishop NOT the White color Bishop which was needed to support the h1 thru a8 diagonal that it needed to support the promotion of the White pawn to a8
