There are just two lines more to take up. We have had to compress some of the variations due to space limitations.

[IM Robert Ris]
1.e4 e5 2.Nf3 d6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3 Be7 6.Bf4 0–0 7.Qd2 d5
This is the main line but if you are not familiar with the position it is hard to play this move.
8.Ndb5
[8.exd5 Nxd5 9.Nxd5 Qxd5 leads to comfortable play for Black]
8…Bb4
If 8…Na6 then simply 9.exd5. The major alternative here is 8…c6 9.Nc7 and then it is either:
• 9…Bb4 10.f3 (10.exd5 Nxd5 11.Nxa8 Qf6 12.Be3 Nxc3 13.a3 Ba5 14.Bd3) 10…d4 11.Nxa8 Nd5 (11…dxc3 12.bxc3!) 12.exd5 Re8+ 13.Be2 Qf6 14.0–0–0 dxc3 15.Qd4 Aitbayev,A (2321)-Kazhgaleyev,M (2618) Astana 2011 1–0 (27);

9…c6
[9…Nxe4? 10.Qxd5 Qxd5 11.Nxd5 White’s pieces are way more active]
10.Nc7 Nxe4 11.Qd4
The move 11.Qe3 does not have a great score 11…Nxc3 (11…Bxc3 12.bxc3 g5 13.Qxe4 Qxc7 14.Qxh7+ Kxh7 15.Bxc7 Bf5 16.f3 Nd7 17.g4 Bg6 18.h4 gxh4 19.c4 Rac8 20.Rxh4+ Kg7 21.Ba5 1–0 (25) Gyimesi, Z. (2553)-Nevednichy, V. (2548) Nova Gorica 2004) 12.bxc3 Ba3+

11…Bxc3
He can also take with the knight: 11…Nxc3 12.bxc3 Ba3+ 13.Kb1 Nd7 14.Qa4 (probably White should take on a8 14.Nxa8) 14…Be7 15.Nxa8 Nc5 16.Qxa7 Ne4 17.Be5 Bc5 18.Qa4 Qe7 19.Bd3 (19.f4 Qxe5) 19…Qxe5 20.Bxe4 in this position Black is much better although Grischuk went on to win the game.

12.bxc3 g5?!
[12…Qe7 13.c4 (13.Rd3 Be6 14.Nxa8 c5 15.Qe3 c4 16.Rd4 Qa3+ 17.Kd1 Nxc3+ 18.Kd2 Nb1+ 19.Kd1 Nc6 20.Nc7 ½–½ (45) Savchenko,B (2596)-Rapport,R (2704) Riga 2014 20…Qb2 21.Be5 Bf5) 13…Qa3+ 14.Qb2 Qa5 15.Nxa8 Nxf2 16.Be2 Nxh1 17.Rxh1 Na6 (17…Re8?! 18.Bd2 Qc5 19.Re1 dxc4 20.Nc7 Re4 21.Bf3 Rxe1+ 22.Bxe1) 18.Bd2 Qd8 19.cxd5 Qxd5 20.Bxa6 bxa6 21.Re1 White is clearly better.

13.Bg3 Nxg3 14.hxg3 Qxc7 <D>
POSITION AFTER 14…QXC7
Initially the engines think that White is losing here but now …
15.Rxh7! Kxh7 16.Qf6!
[Bd3 and Rh1 are coming]
16…Rh8 17.Re1 Be6 18.Qxg5 Bf5 19.Bd3 Bg6

This is the advantage of playing 7…c6 instead of 7…a6, because now the white knight cannot go to d5.
10.Na4!
The knight looks awkward on the edge of the board but it also prevents the march of Black’s a-pawn.
Putting the knight on e2 with 10.Nce2?! is a bit inaccurate 10…c5 11.Nf5 Bxf5 12.exf5 Nc6 White has to take some time to reposition his knight on e2. 13.Kb1 (13.g4 Qa5 14.Kb1 c4 15.Nd4 Nxd4 16.Qxd4 d5 0–1 (67) Pourramezanali, A.

10…Bd7
[10…c5?! should be met by 11.Nb5! (the knights on a4 and b5 look crazy but not so easy to profit from that) 11…Qa5 12.b3 Bd7 13.Bxd6 (13.Nxd6 is also good 13…Bxa4 14.bxa4 Qxa4 15.Kb1 followed by Nf5, Bc4. Not so easy for Black to attack while with his knight on f5 White is in a good position) 13…Bxd6 14.Nxd6 Bxa4 15.bxa4 Qxa4 16.Kb1 Qa3 17.e5 Nfd7 1–0 (51) Pijpers, A. (2465)-Milosevic, M. (2306) Porto Carras 2018 18.e6! fxe6 19.Qe1 with the idea 19…Rf6 20.Qe4]
11.b3
[11.g4 c5 12.Nf5 Bxa4 13.Nxe7+ Qxe7 14.Bxd6 Qe8 15.Bxc5 a5 leads to very sharp play but I am not sure White should go into this]
11…d5
[11…c5 12.Nb5 transposes to the game of Pijpers]
12.g4!
[12.e5 isn’t so great 12…Nh5 13.Be3 c5 14.Nxc5 Bxc5 15.g4 Nf6 16.exf6 Qxf6 suddenly Black gets excellent play 17.Kb1 Re8 18.Bf2 a5 19.h4 a4 20.Qg5 axb3 21.cxb3 Qb6 22.Rh2 (22.Qxd5) 22…Nc6 23.Nxc6 Bxf2 24.Nxb4 Qxb4 25.Rxf2 Rxa2 26.Kxa2 Ra8+ 27.Kb2 Qa3+ (27…d4!! 28.Qc1 Be6 29.Bc4 Bxc4 30.Qxc4 Qa3+ 31.Kc2 Qa2+ 32.Kc1 Qxf2 33.Qxd4?

12…dxe4 13.fxe4
White’s pawns are hanging but what matters are the open files to Black’s king.
13…c5
[13…Bxg4 14.Be2 c5 15.Bxg4 Qxd4 16.Qxd4 cxd4 17.Bf3! White is winning material because of the threatened e4–e5]
14.Nf5 Bxa4 15.Qxd8 Bxd8 16.bxa4 Nc6 17.e5 Nxg4 18.Bg2 Ngxe5 19.Rhg1 Rc8
[19…g6 20.Bxe5]
20.Bxc6! Nxc6 21.Rxg7+ Kh8 22.Rd6! Bc7 23.Be5! 1–0
Sedlak resigns because after 23.Be5 Bxd6 (23…f6 24.Rdd7) 24.Rg8+ Kxg8 25.Nh6# beautiful line.
Well, I think you will agree with me that IM Robert Ris makes quite a compelling argument.
