[Event "Helsinki"] [Site "?"] [Round "0"] [White "Smyslov"] [Black "Barcza"] [Result "1-0"] [ECO "C64"] [Opening "Spanish: Classical, 4.c3 Nf6"] 1. e4 e5 2. Nf3 Nc6 3. Bb5 Bc5 4. c3 Nf6 5. d4 exd4 6. e5 Nd5 {Although th e knight at d5 seems to occupy an important post in the center, it will be difficult for Black to maintain the outpost as White increases the pressure.} 7. O-O O-O { 7...dxc3 is not playable because the knight at d5 can be captured by the queen. } 8. cxd4 Bb6 9. Bc4 {Since the bishop occupies b6, there is no good square for the knight to retreat to.} 9... Nce7 {9...Nde7 10.d5 Nb8 Black's forces are driven backwards and White dominates the center.} 10. Bg5 { An important pin, which indirectly reduces the support of the knight at d5.} 10... Qe8 {What else? The pin must be broken! 10...c6 11.Bxd5 cxd5 12.Nc3 Here the weakness at d5 will be critical.} 11. Qb3 {The consistent application of pressure at d5 means that Black can do little but try to hold things together.} 11... c6 12. Nbd2 {White continues to develop all of the pieces, while Black lags far behind. We can see that this knight is headed for d6, via e4.} 12... h6 {12...Bc7 13.Ne4 Nb6 14.Nd6! Bxd6 15.exd6 Nxc4 16.dxe7 Black's failure to develop has resulted in a loss of the rook at f8.} 13. Bxe7 Nxe7 {Even a quick glance at the board reveals White's domination, thanks to the superior mobilization of the forces.} 14. Ne4 d5 {14...Nf5 15.Nd6 Nxd6 16.exd6 The bishop at c8 is trapped and White will quickly bring two rooks on to the e-file.} 15. exd6 Nf5 {Black is too preoccupied with regaining the little bit of material. The pawn at d6 is weak, and more counterplay could have been achieved by sacrificing a second pawn in order to get some pieces into play. 15...Nd5 16.Bxd5 cxd5 17.Qxd5 Be6 18.Qxb7 Bc4 19.Rfc1 Rb8 20.Qe7 Qb5 Black might have had a little bit of counterplay here.} 16. Rfe1 { The threat is Nf6+, exposing the queen on e8 to attack.} 16... Qd8 { 16...Qd7 17.Ne5!} 17. Ne5 Nxd6 18. Nxd6 Qxd6 19. Bxf7+ Rxf7 { 19...Kh8 20.Ng6+ Kh7 21.Nxf8+} 20. Qxf7+ Kh7 21. Nc4 { Black, already down the exchange, resigned.} 1-0
