⚫️Dubov,Daniil (2683)
🔸½-½

📘 9...b5!?
An interesting and very rare move which introduced by Cuban grandmaster, Walter Arencibia in 1998.
The idea behind the move is controlling c4 square and preventing of Qa4 and Bc4. If:
10.B×b5 Qa5 Black has enough compensation.
10.Rc1 Ba6 11.Be2 b4

🔸Ivanchuk,V
🔸Tabatadze,T
🔸Leningrad

📘 14.Ra4!
White prevents ...c5-c4, defends e4 horizontally along the rank and vacates the long a1-h8 diagonal.
14.Qf1 Nd4 15.Rg3 c4(15...e6!?) 16.Bxc4 Nxc2.
14.Nxb5 axb5 15.Bxb5 Nxe4 with a complicated game.

⚪️#154 (Strategy-White to Move)
🔸Ivanchuk,Vassily (2695)
🔸Anand,Viswanathan (2720)
🔸Buenos Aires 1994

📘 17.h4!
Ivanchuk initiates a kingside assault based on the opening of the h-file with h4-h5.
17.Bxc5? Rxc5 It is obvious that after this exchange black is ok. Without his dark-square bishop, white cannot hope to succeed an attack against the enemy king.
17.Bd4 Bxd5 18.exd5 Bxd4 19.Qxd4 Qf8 with the idea of Qf8.
