[Event "1st olm final"] [Site "London ENG"] [Date "1927.07.29"] [Round "15"] [White "Richard Reti"] [Black "Roberto Grau"] [Result "1-0"] [ECO "D06"] [Annotator "carrobie,robbie"] [PlyCount "34"] [EventDate "1927.07.18"] 1. c4 c5 2. Nf3 Nf6 3. d4 d5 {a) black plays for symmetry, early exchanges and a quick draw. The superficial character of this view is demonstrated quickly enough in this game. Simplification by itself does not produce a draw, it is mainly a question of positional advantages} 4. cxd5 cxd4 {b) both ...QxP and .. .KxP lose time to 5.Nc3 and 5.e4 respectively} 5. Qxd4 Qxd5 6. Nc3 Qxd4 7. Nxd4 a6 {c) ...e5 looks plausible , but would involve black in difficulties, as white would obtain a strong initiative. for example 8.Nb5 Na6, 9.g3 and black is badly off because his knight is badly placed and white king bishop will exert great pressure along the long diagonal.} 8. g3 e5 9. Nb3 Nc6 {d) in view of the great power of whites Kings Bishop later on, black should have tried to neutralise the pressure on the long diagonal with ..Bd7 ...Bc6} 10. Bg2 Bd7 11. O-O Be7 {e) by playing ...e5 black has exposed the d5 square to invasion, by playing ...h6 he would have been able to retain his knight on f6, which is essential if he is to prevent white from posting a centralised knight of d5.} 12. Bg5 {f) as set forth white will remove the f6 knight and centralise his own at d5, with great effect.} O-O {g) this is definitely bad as blacks king is too far removed from the menaced centre squares thus making whites tactical threats more serious than ever, better was 0-0-0 which would have kept the king near the centre and saved a tempo in bringing the black rook to the d file.} 13. Rfd1 {h) there we have it, white is threatening to win a piece with Bxf6} Rfd8 {i) against 13...Rad8 white proceeds in exactly the same way, 14.Bxf6 , no matter what black plays, he will lose at least a pawn.} 14. Bxf6 gxf6 {j) no better is . . . Bxf6, white wins at least a pawn. cannot type any more analysis.} 15. Nd5 {k) white threatens to win at least the exchange , with Nb6} Rab8 16. Nc5 {l) white threatens to win a piece by 17. Nxe7+, ...BxN is clearly inadequate after 17.Nxf6+ and Nxd7. ...Be8 is better , but still unsatisfactory in view of ...17.Nxe7 Nxe7, Nxb7} Kf8 17. Nxf6 Bxf6 {m) No matter how black plays he must come out the exchange and a pawn down. SUMMARY: black neglected to struggle for control of the centre. He did not attempt to neutralise the pressure of whites Kings bishop on the long diagonal; he allowed white to seize control of the vital square d5; he weakened his pawn position; he did not take adequate measures to dispute the d file. all these seemingly minor sins were fatal in their cumulative effect.} 1-0
grading
1-3 , positional werewolf of London, awoooo, calculates every move 20 ply
4-7, positionally aware, watch out for them weak squares, centralised knights and
open files
8-11 - positionally adept, can accumulate small advantages to build an
overwhelming advantage
12-13 probably around at Magnus Carlsons housing helping him work on his opening
repertoire.
