Maybe, but the list was made before Elista, when it was hard to say if his shared first with Svidler in Dortmund was a better result than for example Topalov's shared first in Wijk and win in Sofia.

How dare you, <lost emperor>?

… he is the greatest artist amongst chess players. Whilst in all of Schlechter’s beautiful games there is to be found playful delight comparable to the joyful dance, and whilst with Lasker a dramatic struggle captivates the onlooker, with Rubinstein all is refined tranquillity; for with him in building up his game the position given to every piece is the necessary one. It is not a matter of a fight for him [the contrast here is clearly with Lasker], but the working out of a victory, and so his games create the impression of a great structure from which no stone dare be lifted.

First we have to gather a few facts. It’s not much but discussing the subject with even less knowledge about it wouldn’t lead anywhere. I’ll add a discussion afterwards.

1903

<First Salwe-Rubinstein match, 04-26 to 06-07> Rubinstein drew the 20 year older Salwe with 7-7 unexpectedly. Salwe was already in 1882 considered to be one of Warsaw’s best players and moved to Lodz twelve years later. He belonged to Poland’s strongest players prior to the First World War.

<Third All-Russian Chess Championship in Kiev, 09-01 to 09-26> Due to their drawn match, Salwe and Rubinstein qualified for this event. It was Rubinstein’s (and Salwe’s) first major tournament. Rubinstein scored 11.5/18 (+10 =3 -5) and ended up on place 5/19 ahead of players like Znosko-Borowsky, Schiffers and Dus-Chotimirsky. Chigorin won the event.

1904

<Lodz Handicap tournament, 1903-12-06 to 1904-02-14> Rubinstein was the runner-up behind Salwe with 18.0/21 (+16 =2 -2) ahead of Janowsky (15.0/21).

<Second Salwe-Rubinstein match, March and April> Rubinstein won the match. The most likely result is 5.5-4.5 (+4 =3 -3) but sometimes the result is given as 6-4 or 6.5-3.5 in Rubinstein’s favor.

1905

<Barmen main international tournament, 08-14 to 08-30> Rubinstein’s first international tournament ended with a shared first place (together with Duras – they drew two tie-break games) with 12.0/15 (+11 =2 -2).

<First Mieses-Rubinstein match, at the end of October> Rubinstein won 3-0.

1906

<Fourth All-Russian Championship in St. Petersburg, 01-02 to 01-23> Rubinstein shares second place with Blumenfeld with 12.0/16 (+8 =8 -0) behind Salwe but ahead of Znosko-Borowsky, Alapin, Dus-Chotimirsky, etc. Maliutin and Rubinstein displayed great sportsmanship after Blumenfeld’s provocations (round 12, Rubinstein vs B Maliutin, 1906).

<Lodz triple-round match tournament, possibly held in April or May> Rubinstein won the tournament and his mini-matches against Chigorin (+2 =0 -1), Flamberg (+2 =1 -0) and Salwe (+1 =2 -0).

<Ostende five-stage thirty-six-player tournament, Juna and July> Rubinstein came in third with 19.0/30 behind Schlechter (21.0 points) and Maroczy (20.0 points) but ahead of players like Bernstein, Burn, Teichmann, Marshall, Janowsky and Perlis (those are the players who survived to the fifth stage – players like Duras, Znosko-Borowsky, Blackburne, Salwe and Spielmann failed to do so).
