🔸Hoogeveen Matches 2017
🔸Round 3
⚪️Adhiban,B (2671)
⚫️Van Foreest,Jorden (2609)
🔸0-1
📘 30.Kf2?
A miscalculation from the Indian grandmaster.
30...B×b4 31.R×e1 Bc5!+ 32.Kf1 B×g2!+ 33.K×g2 R×e1 -+
Correct continuation was 30.R×e1 R×e1 31.Kf2 B×b4 32.K×e1 B×g2 with only slightly better chances for black.

📘 1.g5?! allows Nh5, while 1.Ng3 with the idea of g5 is not the sharpest option. The best attacking idea is to transfer the queen to the kingside by the typical 1.Qe1!
⚪️#88 (Strategy-White to Move)
🔸Spassky,Boris
🔸Kortschnoj,Viktor
🔸Moscow 1964
📘 1.e3 is a normal move that does not punish black's mistaken c5 on the previous move. 1.Nf3 seems solid but passive and closes Bg2. 1.Nd3! with idea of Nf4 and taking d5 leads to clear advantage for white.
In general Nf3-e5-d3-f4 is a typical maneuver in this pawn structure.
1.Nd3! cxd4 2.Bxf6! Bxf6? (2...dxc3 3.Bxc3 +/-) 3. Nxd5! +-

⚪️Wei,Yi (2740)
⚫️Ivanchuk,Vassily (2732)
🔸½-½
📘 11.e5!?
This move was introduced in 2005 by Topalov in his game against Svidler. The tactical point behind this move is that after the risky 11...Bxe5?! white can take back the pawn by playing 12.Qh5 Bd6 13.Rxe6+ with slightly better chances for white.
11...Bf8 12.Ne2
This is the move that Topalov played in 2005 with the idea of Nf4 and c4. Alternatives are Polgar's Na4, and Motylev's Nb1 both with the idea of c4.
12...Ne7 13.Ng3
This is the novelty. Wei Yi tries to improve Topalov's game by selecting a different square for the knight but with a similar plan of c4.

📘 8.Na3
A modern approach. Instead of the typical, and classical maneuver of Nb1-d2-f1-e3 or g3 white grabs space on the queenside and tries a new path: Nb1-a3-c2-e3
White can also consider exchanging bishops by Be3 after playing Nc2.
