The Chain on Q5 (2 of 2)

Point Count Chess, NO.21, p38
Tarrasch v. Teichmann, 1905

This example shows White being successful with an Advanced Chain at his Q5 (d5), from a line in the Ruy Lopez.

Despite the Advanced Chain gaining White a Tempo and leaving Black "momentarily very cramped," and despite White's eventual victory that comes with it, H&M-S appear to advise caution when playing this particular Advanced Chain, as they say: "the move requires rather precise calculation that White's queen-side pawn storm will become menacing before Black can do any harm on the king-side."

1. The Ruy Lopez, leads to White's Advanced Chain at his Q5 (d5).

 The Advanced Chain,The Chain on Q5 (2 of 2), After 1.e4 e5 2.Nf3 Nc6 3.Bb5 After 1.e4 e5 2.Nf3 Nc6 3.Bb5, we see the position of the Ruy Lopez. White's e4-Pawn, from his very first move, becomes the base Pawn in, what will be, White's Advanced Chain (e4,d5). I've highlighted the three Pawns that will be part of White's Advanced Chain, all the way through to the end of the game, contributing to White's victory.
 The Advanced Chain,The Chain on Q5 (2 of 2), After 3...a6 to 5...Be7 After 3...a6 to 5...Be7, the Ruy Lopez has headed down a variation of the Morphy Defence (3...a7-a6), which sees White's light-Bishop retreat (4.Bb5-a4), Black prepare his Kingside for Castling (4...Ng8-f6 » 5...Bf8-e7); White actually Castles Kingside (5.O-O).

2. Continued Development, leading to White's

 The Advanced Chain,The Chain on Q5 (2 of 2), After 6.Re1 » 7.c3 After 6.Re1 » 7.c3, White plays two moves that support the development of White's Advanced Chain at his Q5 (d5). First, White's King Rook is developed (6.Rf1-e1), to support what will be the Chain's base Pawn (e4). Then, White's c-Pawn is developed (7.c2-c3), to support the d-Pawn's imminent advance to d4, en route to d5. White's c3-Pawn ensures he will still have a Pawn to push to d5, if, for example, Black tried capturing his original d-Pawn (e.g. ...e5xd4, c3xd4, and then d4-d5).
 The Advanced Chain,The Chain on Q5 (2 of 2), After 8.h3 After 8.h3, White develops his h-Pawn (8.h2-h3), to prevent Black's light-Bishop (Bc8) coming down to Pin White's Nf3, which provides joint support for the advance of White's d-Pawn (d2-d4). This could be a more significant move than merely preventing Black's light-Bishop developing to g4, since my Comparison between No.18 & No.19 suggested the cramping of the Black light-Bishop, played a part in the success of White's Advanced Chain. Certainly worth considering.
 The Advanced Chain,The Chain on Q5 (2 of 2), After 8...Bd7 9.d4 After 8...Bd7 9.d4, White develops his d-Pawn, preparing for its second push into an Advanced position, at the head of what will be White's Advanced Chain on Q5 (d5). Black effectively completes his development phase, when he brings out his light-Bishop (8...Bc8-d7), to Connect his Major Pieces (Ra8-Qd8-Rf8). And then White brings out his d-Pawn (9.d2-d4), which is attacked by two Black units (e5-Pawn & Nc6), but defended by three White units (c3-Pawn, Nf3 & Qd1).
 The Advanced Chain,The Chain on Q5 (2 of 2), After 9...h6 10.Bc2 After 9...h6 10.Bc2, Black plays a similar move to White, in developing his h-Pawn (9...h7-h6), to stop White's dark-Bishop (Bc1) moving out to Pin his Nf6, from g5. White takes the opportunity to safeguard his light-Bishop, by returning it to a position of greater safety (10.Ba4-c2).
 The Advanced Chain,The Chain on Q5 (2 of 2), After 11.Nbd2 » 12.Nf1 » 13.Ng3 After 11.Nbd2 » 12.Nf1 » 13.Ng3, White brings his Queen Knight across to g3, in three consecutive moves (11.Nb1-d2 » 12.Nd2-f1 » 13.Nf1-g3). Both White Knights (Nf3 & Ng3) each provide additional support for the d4- & e4-Pawns, that will form White's Advanced Chain on Q5 (d5). In addition, the Knights and dark-Bishop (Bc1) help delay Black, at the very least, from making any further advances on the Kingside, so that White can focus on his plans over on the Queenside.
 The Advanced Chain,The Chain on Q5 (2 of 2), After 14.Be3 After 14.Be3, White develops his dark-Bishop (14.Bc1-e3), so it will be patrolling the diagonal up to a7, when White advances his d4-Pawn into the Advanced Chain on Q5 (d5).
 The Advanced Chain,The Chain on Q5 (2 of 2), After 15.Qd2 After 15.Qd2, White develops his Queen (15.Qd1-d2), connecting his Rooks, but at the same time ensuring his Queen maintains her support for the d4-Pawn.

3. White gains the Advanced Chain on Q5 (d5)

 The Advanced Chain,The Chain on Q5 (2 of 2), After 16.d5 After 16.d5, White gains the Advanced Chain on Q5 (d5), with the second push of his d-Pawn (16.d4-d5).

The Result of the Chain on Q5 (2 of 2)...

 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 16.d5 Nd8 After 16.d5 Nd8, White's d-Pawn steps forward (16.d4-d5), to create the Advanced Chain on Q5 (d5). In doing so, it forces Black's Nc6 to flee to safety (16...Nc6-d8). The creation of White's Advanced Chain also clears the g1-f7 diagonal, for White's dark-Bishop to patrol and attack deep into Black's territory. Black's mobility is quite restricted on the Queenside; his trouble moving his Pieces about in this region is a sign of his Cramped Position.
H&M-S describe Black's position as "momentarily very cramped."
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 17.c4 After 17.c4, White enhances his Advanced Chain, advancing the c3-Pawn (17.c3-c4) to form an Advanced Salient (c4,d5,e4). Black now has double the work to do, if he's to destroy White's Advanced Chain on Q5 (d5). That's one of the core benefits of forming an Advanced Salient.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 18.b3 After 18.b3, White's b-Pawn (18.b2-b3) reinforces the Advanced Chain on Q5 (d5), coming from the direction of the Queenside. BUT, this is just a temporary measure, as it's real objective is to help White deal with the threat from Black's advancing a-Pawn. H&M-S point out White's b-Pawn move is a "necessary preliminary to P-R3 (a2-a3) and P-N4 (b3-b4). If at once 3 P-R3 (18.a2-a3), then P-R5 (18...a5-a4) prevents White from ever getting a pawn to QN4 (b4)."
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 19.a3 » 20.b4 After 19.a3 » 20.b4, in successive moves, White presses ahead with his Pawn advance (19.a2-a3 » 20.b3-b4), to counter the threat posed by Black's a5-Pawn.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 21.Qc3 to 28.Nc3 After 21.Qc3 to 28.Nc3, White brings the majority of his force across to the Queenside, seeming content that his Kingside is adequately defended against any attempt by Black to try something there. Also in that sequence, White reinforced the Advanced Chain on Q5 (d5), from the Kingside, with the advance of his f-Pawn (23.f2-f3). This also helps reinforce White's Kingside, enabling White to take his Pieces across for the impending Queenside offensive.
Incidentally, that initial move by White's Queen (21.Qd2-c3) is to in a bid to defend his Ra1. After Black's last move (20...Ra8-a7), H&M-S say that White is anticipating increased pressure on the a-file, with the imminent formation of a Black Rook Battery, and so "White immediately guards his QR1 (a1) to prevent Black from getting command of the file."
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 28...Nf6 29.Nb5 Bxb5 30.cxb5 After 28...Nf6 29.Nb5 Bxb5 30.cxb5, White's Advanced Salient is dissolved back down to the Advanced Chain on Q5 (d5), as the relocation of Black's King Knight (28...Nd7-f6) leads to White exchanging a Knight for Black's light-Bishop (29.Nc3-b5 Be8xb5). As White's c4-Pawn completes the trade (30.c4xb5), it breaks apart the Advanced Salient, leaving behind the Advanced Chain (g2,f3,e4,d5). White also takes on Doubled Pawns (b4,b5).
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 31...axb4 32.axb4 After 31...axb4 32.axb4, the a-Pawns are exchanged (31...a5xb4 32.a3xb4), leaving White's Doubled Pawns (b4,b5) as a permanent structure, which actually isn't the weakness it often can be, as it remains all the way through to the end of the game, preventing Black from breaking out of his restricted position, down the Queenside.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 33.Qf1 to 37.Qxa1 After 33.Qf1 to 37.Qxa1, White enhances his advantage with the Advanced Chain, by Simplifying the position, with the exchange of both sets of adverse Rooks ... Removing these threats serves to increase the survivability of the Advanced Chain -- this is where the structure is enhanced.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 38.Qa6 After 38.Qa6, White's Queen is moved to the a6-Outpost (38.Qa1-a6). Her removal by Black's Queen will leave White with a Passed Pawn (b5xa6), which can be Protected (b4-b5). The threat allows White to turn his attention to attacking Black's Kingside, with his Pawns, over there.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 39.Bc4 to 43.Bh3 After 39.Bc4 to 43.Bh3, White has mobilized his light-Bishop (39.Bb3-c4 » 42.Bc4-f1 » 43.Bf1-h3) and Kingside Pawns (40.g2-g3 » 41.h3-h4), ready to attack Black's Kingside Pawns.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 44...h5 to 47...gxh5 After 44...h5 to 47...gxh5, White has successfully cleared the g-file of Pawns, in an exchange (47.g4xh5 g6xh5) that removes a key threat to the base of White's Advanced Chain on Q5 (d5). Black's Backward f7-Pawn cannot be advanced to attack White's e4-Pawn in the Advanced Chain, as it would risk White gaining a Passed Pawn (e4xf5) ... At the very least, White's f3-Pawn could replace the e4-Pawn (if captured by ...f7-f5xe4, f3xe4), maintaining the Advanced Chain.
 (RESULT) The Advanced Chain,The Chain on Q5 (2 of 2), After 68.Bd8 After 68.Bd8, at the point when Black resigns, both White's Advanced Chain on Q5 (d5) and the "good" Doubled Pawns (b4,b5) still remain intact, proving White has been successful with his Advanced Chain.

Summary of the Chain on Q5 (2 of 2)...

1. A variation of the Ruy Lopez, Morphy Defence (1.e2-e4 e7-e5 2.Ng1-f3 Nb8-c6 3.Bf1-b5 a7-a6), can lead to White gaining the Advanced Chain on Q5 (d5).

2. H&M-S say the move to gain this particular Advanced Chain, "requires rather precise calculation that White's queen-side pawn storm will become menacing before Black can do any harm on the king-side." In the game, White managed to navigate the potential dangers by first bringing his Queen Knight across to the Kingside (11.Nb1-d2 » 12.Nd2-f1 » 13.Nf1-g3), so the two Knights and the Bc1 can work together to prevent Black attacking down the Kingside. This enables White to focus on the Queenside pawn storm. This all comes while White's d- & e-Pawns sit in Phalanx formation, in the Center, before the d-Pawn makes the advance that creates White's Advanced Chain on Q5 (d5).

3. White gains the Advanced Chain on Q5 (d5), after completing the development phase by advancing his Queen (15.Qd1-d2), which connects the two Rooks. And then he pushes his d-Pawn on again, into the Advanced position (16.d4-d5).

4. White continues to focus his effort on the Queenside, mobilizing his a- & b-Pawns, to meet the threat from Black's a5-Pawn. The order of White's mobilization is important, to avoid Black pushing the a5-Pawn down to a4, which would cause problems for White's Queenside attack. First, White pushes his b-Pawn (18.b2-b3), so it sits in support of Queenside portion of his Advanced Salient (c4,d5,e4). Second, White brings the a-Pawn one pace forward (19.a2-a3). Third, White pushes his b3-Pawn a second time (20.b3-b4), so it not sits at the head of its own Chain (a3,b4), attacking Black's a5-Pawn.

5. White takes on a Doubled Pawn formation on the b-file (b4,b5), following an exchange of his Nc3 (29.Nc3-b5) for Black's light-Bishop (29...Be8xb5). The c4-Pawn breaks apart from the Advanced Salient, to complete the trade (30.c4xb5), and slotting itself into the Doubled Pawn structure, in the process.

6. The exchange of the a-Pawns (31...a5xb4 32.a3xb4) gives White a "good" Doubled Pawn structure. It creates something like an alley of death along Black's portion of the a- & c-files (a5 & a6; c5 & c6), stopping Black's Knights and Backward c7-Pawn from advancing down the Queenside.

7. White Simplifies the position, exchanging both pairs of adverse Rooks off the board, so they're won't threaten either White's Advanced Chain or his exposed Kg1. After the completion of the Rook exchange, by White's Queen (37.Qf1xa1).

8. White blocks off access down the Queenside, so he can turn his attention to the Kingside offensive. White sends his Queen up to the a6-Outpost, keeping Black's Queen at bay.

9. White trades Pawns off the g-file (47.g4xh5 g6xh5), to remove a possible threat to his Advanced Chain, as part of his Kingside offensive.

10. Black eventually resigns, with White's Advanced Chain on Q5 (d5) still intact.
