Despite its solid look, the position has a subtle element of tactic grounded in positional evaluation. After the strong 22.Rd6! , a series of forced exchanges ensues which lead to a double pawn for black on the e-file. The final straw comes as white grabs the pawn on a7 leaving black with a problem of farther passed pawn on the a-file. furthermore, the knight on h5 and the bishop on g7 are passive and black's pawn structure is permanently damaged. All these give white decisive advantage in the endgame, which Salov gradually converted into a full point.
22...Rxd6 (This is forced due to 22...Nf8 23.Ng5! and all of Rxd8, Qxf7, Nxf7, and Bd7 are threatened. White wins.)
23.cxd6 Qxd6 24.Bxe6 Qxe6 (If 24...fxe6, then 25.Bxa7)
25.Qxe6 fxe6 26.Bxa7+-.
22...Rxd6 (This is forced due to 22...Nf8 23.Ng5! and all of Rxd8, Qxf7, Nxf7, and Bd7 are threatened. White wins.)
23.cxd6 Qxd6 24.Bxe6 Qxe6 (If 24...fxe6, then 25.Bxa7)
25.Qxe6 fxe6 26.Bxa7+-.
This position comes under the 90% rule. Remember that the move you want to play for positional reasons normally has a 90% chance of working tactically. Of course, that does not count for sacrifices and other brutal approaches as often as it does in quiet positions, but it is still worth investigating if the move you want to play for positional reasons works tactically. Here it does. White is all set up for b2-b4-b5 but cannot protect his c-pawn with moves other than b2-b3. So it is now or never, as this will not change.
12.b4! Bxc4 A very risky decision. It is not difficult to understand what Black was thinking: if White is allowed to execute his plan at least I should bag a pawn. Instead 12...Ne4 13.Nxe4 fxe4 14.Nxe6 Qxe6 15.Qc2 Rfe8 16.Be3 Qc7 17.Rfd1 leads to a comfortable advantage for White.
13.b5! cxb5 14.Ndxb5 Rd8 15.Ba3.

JACKSON WHIPPS SHOWALTER
(born Feb-05-1859, died Feb-05-1935, 76 years old) United States of America
Jackson Whipps Showalter held the title Chess Champion of the United States on several occasions from the 1890s to 1909.
He played matches against Max Judd in 1890 (+3 -7) and 1891-2 (+7 -4 =3), Emanuel Lasker in 1892 (+2 -6 =2), Samuel Lipschutz in 1892 (+1 -7 =7), Jacob C Halpern in 1893-4 (+5 -3 =1), two against Albert Hodges (+7 -6 =4) and (-5 +3 =1), and Adolf Albin (+10 -7=8) in 1894. Following Hodges' retirement, he definitely established a claim to the title by defeating Lipschutz in 1895 (+7 -4 =3).
He defended this title by defeating Emil Kemeny (+7 -4 =4) and John Finan Barry (+7 -2 =4) in successive matches (1896), before losing twice to Harry Nelson Pillsbury in both the Pillsbury - Showalter (1897) (+8-10=3) and Pillsbury - Showalter (1898) (+2-7=3) matches.
Following Pillsbury's death in 1906, he was again considered US Champion until being defeated by Frank James Marshall (+2 -7 =3) in 1909.
He was a regular participant in major international events from 1893 to 1904, scoring wins over World Champions Wilhelm Steinitz and Emanuel Lasker among other notables.
