🔸ARG-ch Final 2017, Buenos Aires
🔸Round 8
⚪️Flores,Diego (2574)
⚫️Villanueva,Mario (2451)
🔸1-0
📘 16.N×g7! K×g7 17.Nd5 +/-
The knight on f6 is defenseless.
⚪️#73 (Strategy-White to Move)
🔸Kortschnoj,Viktor Lvovich (2670) - Karpov,Anatoly (2700)
🔸Candidates final Moscow 1974
📕 #73

11.Qd2!?N
Kortschnoj's novelty came as a shocking surprise to young Karpov!
11...Nxd5?! (11...Na5 can be an intetesting novelty; another option which has been played by Banikas twice is 11...Ba6 12.b3 Nxd5 13.Bxd5 Bxg5 14.Qxg5 Nb4 15.Bxa8 Nc2+ 16.Kd1 7Qxa8 17.Kxc2 Qxh1 with slightly better chances for white in a middlegame with opposite colored bishops.)
12. Bxd5 Rb8?? (GM Fontaine made a draw against Tkachiev by playing Matanovic's suggestion, 12...Bxg5)
12.Nxh7!! +-
This knight is untouchable!
If 12...Kxh7 13.Qh6+ Kg8 14.Qxg6 Kh8 15.Qh6 Kg6 16.Be4! f5 17.Bd5 with an inevitable checkmate.
⚪️#74 (Strategy-White to Move)
🔸Nimzowitsch,Aron - Salwe,Georg
🔸International Masters Karlsbad 1911
📕 #74

One of the most important concepts that have been deeply discussed by Nimzowitsch is blockade. White manages to blockade his opponent's pawns by establishing his pieces on the d4 and e5 squares just in front of black's central pawns.
9.b4! Be7 10.Bf4! fxe5 11.Nxe5 Nxe5 12.Bxe5 Nf6 13.Nd2 0-0 14.Nf3 Bd6 15.Qe2 Rac8 16.Bd4 Qc7 17.Ne5 +/-
A dream position for Nimzowitsch!

📘 41...Kh8??
In a superior but complicated position with a piece up, the Argentinian grandmaster made a blunder. He could protect his king by playing 41...Bg6 42.Nf5 Kh8!.
