Ulhumbrus: In his manual of chess Lasker gives the move 6...Na6 an exclamation mark. In the position after 14...Rad8 White has the bishop pair.
Lasker manages however to bring about a position in which White's bishop pair counts for nothing.
Lasker does this in the following way: After the black squared bishops are exchanged following the advance ...c5 White's king's bishop enjoys no scope.
This suggests the double question of how the player facing the bishop pair may bring about such a state of affairs, and how the player possessing the bishop pair may prevent it.
It is conceivable that just one or two corrections may make all the difference to the side which can manage them.
For example suppose that taking the sequence of moves 13-16 as played in the game, White can manage the move Bf4 in place of the move Be3 and perhaps the move Kh1 in place of the move f3, while Black plays the same moves.
Then one variation is 13 Rfd1 Qa5 14 Bf4 Rad8 15 Kh1 c5 and now 16 Nb5 threatens 17 Bc7 or 17 Nd6 while 16 dxc5 Bxc5 17 Nb5 threatens 18 Bc7 and 18 Nd6.
That is a beginning.
