1. e4 e5 2. Nf3 Nf6 {For about 20 years starting in the mid 1980s the Petroff
was what the Berlin Defence is today: a threat to make 1.e4 a boring draw, and
a big part of Kramnik's Black repertoire.} 3. Nxe5 d6 4. Nf3 Nxe4 5. Nc3 {
This is White's latest attempt to inject life into what can otherwise turn
into a well-worn equality.} ({The main line used to be this:} 5. d4 d5 6. Bd3

the players go for a pawn race, aiming to use the hooks on b3 andd f6 to open
lines for their Rooks. Black's Bishop is better placed for attack and defence,
so this race might not be White's best choice.} 16. h4 (16. Kb2 a5 (16... b5

winning chances.}) 17. a4 $1 b5 18. axb5 a4 19. Ra1 $11) (16. c4 $5 a6 17. h4

faster.} (20. Rhg1 $142 {gains a tempo over the game line,} Qe7 21. gxf6 Qxf6
