▪️ PGN format

@unitychess
🔸International Fajr Cup (IRI) 2018
🔸Round 9
⚪️Mousavi,Seyed Khalil (2480)
⚫️Maghalashvili,Davit (2506)
🔸½-½
📘 10...cxd4!!
The white king is in the center so Black has made a creative sacrifice to punish him.
11.R×c6 Bb4+ 12.Ke2 Ba6+ 13.Rc4 Rc8 14.Q×d4 f6 15.Kd1 e5 16.Qd3 Qd7 -/+
The position is very difficult for White.

🔸Round 9
⚪️Noroozi,Omid (2351)
⚫️Mosadeghpour,Masoud (2518)
🔸0-1
📘 15.Nd5?
Better moves are 15.f5 and 15.a4
15...N×d5 16.B×d5 Bh3 17.Bf7+? Kf8 18.Rd1 Qd7 19.Bh5?? Qd5 Double Attack 0-1
🔸International Fajr Cup (IRI) 2018
🔸Round 9
⚪️Quparadze,Giga (2481)
⚫️Molaei,Mohammadamin (2327)
🔸1-0
📘 6...Qb6?!
6...Nf6 with the idea of ... d5 is the logical continuation.
7.Nc3! a6
A)7...N×d4 8.Nd5 N×f3+ 9.Q×f3 Qd6 10.0-0 +/-
B)7...B×d4 8.N×d4 Q×d4 9.Qe2 Nf6 10.Be3 +-
In either case, White has more than enough compensation for the pawn.
8.Ba4 N×d4 9.Nd5 N×f3+ 10.g×f3 Qd6 11.Bf4 Be5 12.B×e5 Q×e5 13.Rc1 +-
🔸International Fajr Cup (IRI) 2018
🔸Round 9
⚪️Kasparov,Sergey (2472)
⚫️Faghirnavaz,Ali (2248)
🔸1-0
📘 42.a4 R×a4??
A blunder.
Black probably could have kept the game and White had a hard time to exploit his advantage.
43.Qc6 Double attack 1-0
⚫️#277 (Strategy-Black to Move)
🔸Baklan,Vladimir (2590)
🔸Bareev,Evgeny (2719)
🔸FIDE Wch k.o. Moscow 2001
📕 23...Qe8!
Very strong. Just as it looks as if white is generating very serious pressure, and holds the initiative, black unpins his knight, reminds white of the d-pawn's vulnerability, and threatens ...Bxf3, and under some circumstances can consider ...Bg6.
⚪️#278 (Strategy-White to Move)
🔸Meduna,Eduard (2471)
🔸Holmsten,Aleksei (2422)
🔸EU-chT (Men) Leon 2001
📕 16.Nbd2!
A dynamic position in which Black has "hanging pawns", the undefended queen on d6 becomes a further factor in black's unappetising task.

Karpov and Kasparov thoroughly enjoyed this decisive checkmate from a living chess display during the opening ceremony of the 27th Chess Olympiad (Dubai, November/December 1986).
