⚫️#661 (Strategy-Black to Move)
🔸Ree,H
🔸Portisch,L
🔸Wijk aan Zee, 1968

There has just been a queen exchange on d1 and one might get the impression that the game is entering peaceful waters. However, Portisch now initiates active measures in which his light-squared bishop will play a crucial role.
7...b6!
Considering that White is eager to play c2-c3 to secure his king on c2, Black hurries to put the bishop on the f1-a6 diagonal, where it will touch the key square on d3.
8.c3?!
After seeing the game, you will probably share my anxious feelings about this natural move!
8.h3 Ba6 9.Be3 0-0-0+ 10.Nbd2 Nf6 11.Kc1 intending b2-b3 and Kb2, with much safer play than in the game.
8...Ba6 9.Bf1
White tries to swap the dangerous enemy bishop.
9...0-0-0+ 10.Nbd2 Bb7!
Very strong. After having displaced its colleague, the bishop shifts to the long diagonal, where it will put pressure on the e4-pawn.
11.Kc2 Nf6 12.Bd3
An awkward square for the bishop;
12...h6 13.Re1 g5!
Black continues with active play. He now intends ... g5-g4 followed by ...Ne5.

⚪️#662 (Strategy-White to Move)
🔸Kramnik,V
🔸Gelfand,B
🔸Belgrade, 1997

White is a pawn down but his active pieces and the weak enemy pawns on c6 and e5 provide compensation. Can you spot Kramnik's strong bishop maneuver?
23.Qc1!
Preparing Bd1-b3 in order to seize the a2-g8 diagonal. This would transform the passive bishop on f3 into a terrific piece now that Black has no light-squared counterpart.
23...Qc4
Gelfand searches for relief in a queen exchange.
24.Bd1 Qxc1 25.Rxc1 Rfc8 26.Bb3++/-
