1.e4 c5 2.Nf3 Nc6 3.Bb5{[#] What is in a name? The ‘Rossolimo Variation’ , named after the Russian/Greek/French emigree who eventually found his way to NYC, where he spent the rest of his life. Rossolimo was not the first to play it-it had been played as far back the 1850s, and maybe even earlier-but perhaps it is that Rossolimo’s games popularized the system associated with it. IN ANY CASE, today this system is one of the most important anti-Sicilian lines in modern tournament praxis, and occurs at all levels of play, even at the world championships!} g6 4.Bxc6$5 bxc6$5{[#] The last move by both players is not the main line given in the theoretical books, but fashion and modern tastes might soon change that. } 5.O-O Bg7 6.Re1{[#] Considered the most precise. White waits to see how Black intends to develop his Knight before committing himself to c3 or d4.} e5$5{[#]
The theoretical texts that I know don’t like this move, but perhaps this is too dismissive. Many top grandmasters have played it. Curiously, with colours reversed in the English Opening, some texts give this move a ‘?!’ evaluation! In essence, one must be wary of dismissive evaluations without some lines to back it up}
({Not to be recommended is} 6...Nf6$6 7.e5! Nd5 8.c4! Nc7 9.d4! {when Black’s practical results have been depressing. One modern example is} cxd4 10.Qxd4 O-O 11.Qh4 Ne6 12.Nc3 f6 13.exf6

30.Rxf7 {1-0,<strong style="color: red;"> Popov,Iv – Rieger,R , Novi Sad 9-11-2016</strong> })
({The most reliable line is} 6.Nh6$5 7.c3 O-O 8.h3 ( 8.d4 cxd4 9.cxd4 d5 ) d6 ( 8...f5 ) 9.d4 cxd4 10.cxd4 f6 11.Nc3 {with a double-edged game. Black has two Bishops and a solid center, but White has more activity and a game that is easier to play. The theoretical verdict is still out in this line, but I would be happy to play either side.})
7.c3{[#]
The most popular move, and certainly consistent, but not necessarily the strongest. I am a bit surprised that Naiditsch, a player with a reputation for sharp play, did not avail of the opportunity to play more aggressively here.}
( {It could be that Fischer’s speculative} 7.b4$5 { is the strongest:} cxb4 8.a3

Ne7{[#]
Consistent. Alternatives trying to delay this natural move a bit have not convinced. }
({A} 7...d6$6 8.d4 cxd4 9.cxd4 Bg4 10.dxe5 Bxe5 11.Nbd2!{ and Black will soon have to part with his Bishop pair})
({B} 7...Qb6$5 {risky} 8.d4 cxd4 9.cxd4 exd4 10.e5 Ne7 11.Nxd4 Nd5 12.Nc3

8.d4 cxd4 9.cxd4 exd4 10.Nxd4 O-O 11.Nc3{[#]
Now Black must decide how to proceed. Neither theory nor practical results have come to a conclusion here, though Black’s results have not been encouraging. I think it fair to say that things are not so clear and Black’s game may very well be playable, though only just so.}
Rb8$5 {[#]
The most popular move, and quite logical. Many other moves have been tried.}

12.e5$5 {[#]
The sharpest move, but is it the best move? Difficult to say. Suffice to point out that Naiditsch risks nothing with this aggressive move and it is Black who must exercise caution.}
( {Computers like } 12.Rb1$5 {which has been played a number of times in master level chess with reasonable results. However, not everyone would be happy to essentially lose a tempo.})
c5$5 {[#]
Once more there are choices:}

) Bb7 {[#]
Now it is White’s turn to decide how to proceed. I think that White is somewhat better structurally here, but Black’s game should not be underestimated. In many lines he can sacrifice a pawn for piece activity} 14.Be3$5 {[#]
A practical move, but not necessarily the critical line. It appears that Naiditsch’ plan is to rapidly develop his Queen-Rook}
( {Worthy of investigation for the next game is} 14.Ne4! Qb6! 15.Qxd7$14 )
Bxf3$6 {[#]
An imprecision that Black can not really afford in such dynamic situations. Now White gets on top.}

15.Qxf3 Bxe5
( {Logical, but perhaps a safer bet was } 15...Rxb2 16.Bxc5 Re8 17.Qd3$14 )
16.Bxc5 {[#]
Maybe Black had just assumed that this strong move was not possible}
d6 {[#]
An admission of defeat. White has the better pawn structure as well as the more active pieces. Black can only hope that White does not play precisely and maybe let him off the hook}
( {Unfortunately for Black} 16...Bxh2+ {does not work:} 17.Kxh2 Qc7+ 18.Kg1 Qxc5 19.Ne4! Qf5 20.Nf6+! Kg7
21.Qxf5 Nxf5 22.Nxd7 Rxb2 23.Nxf8 Kxf8 24.Reb1 {with a technical win} )
( {Ugly but necessary is} 16...f6! 17.Rad1
Rf7 {though one can forgive Black for not wanting to play this way} )
17.Rad1 {[#]
Good enough, but there is a more precise move that would force the continuation that actually soon occurs in the game. }
( {The strongest move is the immediate} 17.Rxe5! dxc5 ( {Also depressing is } 17...dxe5 18.Rd1 Qe8
( 18...Qc7 19.Bd6 Qb7 20.Qf6 Nc6 21.h4! {and Black is helpless} ) 19.Qf6! Rb7 20.Bd6! {and Black is paralyzed} )
18.Rd1 Qc7 19.Qf6 {is the game continuation} )
Qc7 {[#]
Understandable, but Black resigns himself to certain defeat now}
( {The only chance was to play}17...f6! {with some slim chances of surviving})
18.Rxe5!$16 {[#]
Naiditsch’ play from now one is very energetic. Black is curiously helpless on the Kingside and can only pray}
dxc5 {[#]}
({Black has no better alternative. After} 18...dxe5 19.Bd6! Qb7 20.Qf6 Nc6 21.h4 Rfd8 22.h5 { is hopeless} )
