1.e4 g6 2.d4 d6 3.Nc3 Bg7 4.Be3 a6 5.Qd2 b5 6.h4 !? h5 7.a4 !?
A new trend in correspondence chess that has worked well recently. Black now has a difficult choice: either the queen side closes after b4, or the pawn structure is broken.
7 … b4 7 … bxa4 !? It looks terrible, but now the Black King is gaining a safe haven at the King Wing because the Queen Wing is open.
8.Nd5 a5 I certainly thought of 8 … Nd7 !? 9.Nxb4 c5 10.dxc5 dxc5 11.Qd5 !? A forcing line in which White remains a trade until the end.
9.Nh3 !? A novelty in this post. However, after h5 by Black, establishing a jumper on g5 is a fairly standard pattern.
9 … Bb7 !? 9 … Bxh3 !? 10.Rxh3 With the inclusion of a4 – a5, this trade favors White because Black does not have the space gain a4 – a3, which is a key idea for Black to create a counterplay.
Not at all an easy choice. I’ll provide some sample lines with some basic ideas for both parties. There is a vast field of exploration here.
10.0–0–0 !? Nd7! 11.Bd3 (11.f3 Bxd5 12.exd5 Ngf6 13.f4 Kb8! Aimed at Bb5. (13 … Nb6 14.Bb5 + Rf8 15.Bc6 Nc4 16.De2 Nxe3 17.Dxe3 Wh6 18.Rde1! Ra6 19.Rde1 Rxc6 20.dxc6 De8 21.d5 Bxf4 22.Dxf4 Nxd5 23.Dd4 Nf6 24.Dc4) 14.g4 (14.Bb5 Rxb5 15.axb5 Qa8!) 14 … hxg4 15.Bd3 g3! 16.Ce6 fxe6 17.Bxg6 + Kf8 18.dxe6 Nb6 19.Bg5 Nc4 20.Qf4 d5 21.b3 Qd6! 22.bxc4 Qxf4 + 23.Bxf4 dxc4 Despite two bishops and an extra pawn, I thought White’s advantage was very minimal.) 11 … Qc8! 12.Rhe1 e6 13.Cdf4 Ne7 14.Ng5 0–0 15.Bc4 d5! 16.Bb3 dxe4 17.Kb1 Bd5 18.g4 hxg4 19.h5 Bxb3 20.cxb3 e5 21.dxe5 Nxe5 22.hxg6 N7xg6 23.Nxg6 Nxg6 24.Qd5 c6 25.Qxe4 Re8 26! Qc2 T5 275 Both colors have de many alternatives in this long line. Even in the final position White can just play Ka2 and, comparatively, his king is much safer for a single pawn. 10.Bd3 Nd7 11.0–0–0 transpose.
10 … Nd7 11.Cdf4 Now Black has to do something in the middle because after Ng5 the white squares start to squeak.
11 … e5 !? 11 … c5 !? 12.Bc4! The easiest way for development. 12 … Qc8 13.c3 !? Ba6 (13 … cxd4 14.Bxf7 +! Rxf7 15.Ng5 + Ke8 16.cxd4 With the knight landing on e6 next and Black unable to castling, that’s obvious compensation. 16 … Nf8 17.Rc1 Qd7 18.d5!) 14.Bd5 Rb8 15.Ng5 Ch6 16.Nxg6 !? bxc3 17.bxc3 fxg6 18.Ne6 Bf8 19.c4!? Kb4 20.dxc5 Nf7 21.c6 Nf6 22.0–0 Nd8 23.Nxd8 Qxd8 24.Rfb1
12.dxe5 Nxe5 12 … dxe5 13.Nd5!
13.Bb5 + !? An obvious choice creating a weakness on d6. A long force line follows: 13 … c6! 14.Be2 Qxh4 + 15.Cf2 De7 16.Rd1 Ba6! 17.Qxd6 Qxd6 18.Rxd6 Bxe2 19.Rxe2 Nc4 20.Rxc6 Nxb2! 21.Q7 Nxa4 22.xg6 Rh7 23.f4 Nc3 + 24.Kd3 a4 !? Although White is a bit better (pawn structure and active pieces), I thought Black had enough counterplay with the passer.
13 … Qd7? Trying to prevent White from castling on the Queen wing by hitting a4, but it doesn’t work tactically and White achieves the goal of closing the Queen wing and Black only has a short tempo to get the break d5.
13 … Nf6! Development was the priority here. 14.Bb5 + c6 15.Fe2 Qe7! 16.Td1 d5 17.exd5 Nxd5! The coin swap helps Black because the knights in f4 and g5 cripple the black wing-king. 18.Cxd5 cxd5 19.0–0 0–0 20.Rfe1 Rac8 21.Bd4 Qc7! 22.b3 !? Rfe8! 23.Bb5 Re7! = Black has some weaknesses to protect (a5 / d5) but the pieces are working well and this position is quite defensible.
14.b3 !! Protect a4 and prepare for a long castling.
14 … Nf6 14 … Nxf3 + does not work and the next line shows the importance of the coordination of the parts with respect to the material. 15.gxf3 Bc3 16.Qxc3! It is imperative that Black is prevented from entering Nf6 and therefore every tempo counts. 16 … bxc3 17.Bd4! d5 (17 … Rh6 18.0–0–0! Ba6 19.Bh3 Qc6 20.Nd5! + – Black can barely move and Re1 – e3 – c3 comes along.; 17 … f6 18.Nge6 Ne7 19.0–0–0! Kf7 20.Cc5! dxc5 21.Bc4 + Nd5 22.Bxc3! + -) 18.Bxh8 f6! 19.Nge6 Qd6 20.Rh2 !! The fastest way to access the electronic file. 20 … Bc8 21.e5! fxe5 22.Bb5 + c6 23.Re2 e4 24.Txe4 !! cxb5 25.Be5 Qb6 26.Cc7 + Kf7 27.Td4! + –
15.0–0–0 0–0 16.Bd4 Qe7 16 … Rad8 17.Bb2 Qe7 18.Cd5! Nxd5 19.exd5 Nd7 20.Bxg7 Rxg7 21.Kb1! Avoid any trick on the a1 box. 21 … Nb6 22.Bc4! and White is ready to crush the king wing with g4.
18.Nd5! Bxd5 19.exd5 Nxg5 20.hxg5 f5!? Trying to enter f4 when the jumper in e5 is super solid.
20 … f6 21.f4 Nd7 22.Re1 Qf7 23.Re6! fxg5 (23 … f5 24.g4! + -) 24.Bd3! + –
21.Qf4 !? A technical solution. With the possession of two bishops, it can be a good idea to open with gxf6. But here the light-colored bishop conveniently lands on b5, giving white control of the electronic file. The ability to break the king wing with g4 and c3 break on the queen wing should be more than enough to secure victory.
21 … Nd7 The computer’s first choice. Personally, I thought Nf7 was more difficult because the ladies come out by force.
21 … Nf7 !? 22.Bxg7 Rxg7 23.Dd4 + De5 24.f4 Qxd4 25.Txd4 Nd8 26.c3 !? (26.Bb5 Nb7 27.Bc6 Rab8 28.Bxb7 Rxb7 29.Re1 Rf7 30.Tc4 Ra8 31.Tc6 Raa7) 26 … bxc3 27.Bb5 Nb7 28.Rh3 Nc5 29.Txc3 With the possible trade sacrifice on c5 and the b4 – break, White should be able to break through, although there is still a long way to go.
22.Bb5! Rae8 23.Rhe1 Bxb2 + 23 … Qxe1 24.Txe1 Txe1 + 25.Rd2 Re7 26.Bxg7 Rxg7 27.Bxd7 Rxd7 28.e3! + – White picks up a5 and the king can escape via c4 if necessary.
24.Rxb2 Qg7 + 25.Rb1 Rxe1 26.Rxe1 Nc5
27.Re3! Stop the counter-play with Qc3.
27 … Kh7 27 … Rh8 28.Re2 Qc3 29.e3! + –
28.Re2! Pave the way for the queen to reorient herself.
28 … Kf7 28 … Qc3 29.e3! Qxe3 30.Txe3 Rf7 31.Be8 f4 32.Bxf7 fxe3 33.Rc1! + –
29.Dd2 Re7 29 … f4 30.Qe1! Qc3 31.Qxc3 bxc3 32.b4 axb4 33.a5 + –
30.Re3! Completely avoid Re5.
30 … Qf8 30 … Re5 31.Txe5 Qxe5 (31 … dxe5 32.d6! + -) 32.Qe2! + – When the ladies start, the break c3 simply wins the game because the passer a is very difficult for the rider to stop.
31.Qe2 Rxe3 32.Qxe3 The rest requires no comment as White is set to secure a passer on the queenside with the c3 break.
32 … Qd8 33.Rb2 Kg7 34.c3 bxc3 + 35.Dxc3 + Kg8 36.De3 h4 37.Rc2 Kf7 38.f4 Qb8 39.Dc3 Ne4 40.Dxa5 The start of 9.Nh3 poses serious problems for black players to resolve. Black could have held the game with 13 … Nf6! but the defensive task even after this movement is not easy. In general, I had the impression that the Modern / Pirc is more suited to the OTB game (I have had a few games with both colors) and the game only confirms this impression.
