Re1 {We commence examination of this game in a position in which White's pieces are slightly more active, in particular the bishop on d3 compared to its counterpart on d7.The White king has easier access to the centre for example it would take Black 4 moves to get to the square d6 whilst it would only take the White king 3 moves to get to d4. In addition, the White rook has the possibility of penetrating to the seventh rank and Black has a slight possibility of being mated on the back rank if the R+B stray too far from that region of the board. Black has a queen's side pawn majority but no weakness than can be immediately attacked. In addition, the majority is a far distance from the White king whilst the Black king is closer to White's majority hence may be able to assist in restricting the generating of a passed pawn. Black decides to enter a B+P ending where these slight Whte advantages turn out to be retained.} Re8 (28... h5 {allows White to increae the advantages by} 29. Re7 Bc8 (29...
