This may seem obvious but it has been known for players of other countries to play in national championships- even the British Championship had Indian Nationality players playing in it before they made the qualification more stringent. Here Max sacrifices for an attack -the sacrifice seems sound but is so complex its hard to tell.} 1. d4 d5 2. c4 c6 {The Slav Opening was a favourite of Max himself who played the opening in the World Championship against Alexander Alekhine, from both sides. Here he avoids the lines that lead to a Knight pinned to the Queen with 6.e3 instead of 6.Ne5.} 3. Nf3 Nf6 4. Nc3 dxc4 5. a4 {The c6 pawn advance makes the taking of the Queens Gambit pawn on c4 more risky for White to cope with, the move 5.a4 stops an immediate 5...b5 by Black which would hold on to the pawn. It is a common way to play the Slav Defence.} Bf5 6. e3 e6 7. Bxc4 Bb4 8. O-O Nbd7 9. Qb3 Qb6 $6 ( 9... a5 {Thi is far safer keeping the Queen in defence of her King.}) 10. e4 $1 Bg6 (10...
