Nc3 c5 {This is the interesting Tarrasch Defense which its inventor considered to be the only correct reply to the Queen's Gambit. It is an aggressive attempt to grab central space. After white plays cxd5 and dxc5, black will be left with an isolated d-Pawn which may be weak, but it gives black a foothold in the center and his Bs will have open lines. The defense is considered sound because even if black fails to make use of the Bs mobility and winds up in an inferior endgame in which he is tied to the defense of his isolated P, he may be able to hold the draw if he defends accurately.} 4. cxd5 exd5 5. e3 Nf6 6. Nf3 Nc6 7. Be2 Bd6 8. dxc5 Bxc5 {If one plays the Tarrasch it is absolutely essential that they know the ins and outs of playing for and against the isolated d-Pawn. } 9. O-O O-O 10. a3 {At the time this game was played this was a popular line. 10.b3 is more usual, but it produces no better results that the text.} a5 11. Qc2 (11. b3 Be6 12. Bb2 Rc8 13. Rc1 {with equakity. Willim,M (2024)-Jaiveer,M (2217) chess.com INT 2025}) 11... Be6 {The main alternative is 11...Qe7} 12. Rd1 Bb6 13. h3 {While this does no damage to white's position it really serves little purpose.} Qe7 14. Qa4 Rfd8 15. Nb5 {With this move white introduces complications that should slightly favor black.15.Bd2 is solidm but it leads to a lifeless position.} Ne4 16. Bd2 Bf5 {Wenman is playing for a trap to win the Q by ... Nc5. but first the square c2 has to be covered.} 17. Rac1 g5 { Guarding f4 and h4 so now he is ready to spring his trap.} 18. Nc3 {Falling into the trap, but white has calculated that he has sufficient compensation for the Q.} Nc5 {[%mdl 8192] The position is very difficult, but winning the Q leads to a lost position. Correct was 18...Nxf2} 19. Qb5 Ra6 20. Nd4 {Much stronger was 20.e4!} Na7 21. Nxf5 {Technically this should have allowed black to nearly equalize, but psychologically his falling for black's plan to win the Q is understandable.} Qe5 {[%mdl 8192] A square too far. Correct was 21... Qe6} 22. Nh6+ {With black's Q on e6 this would not have been possible.} Kf8 23. Nxf7 {The only move to win.} Qb8 24. Nxd8 Nxb5 25. Bxb5 Ra8 26. Nxd5 {It's instructive to watch how Gibson maneuvers his pieces into their optimal positions.} Qxd8 27. Bc3 Ne4 28. Nf6 Nxf6 29. Rxd8+ Bxd8 30. Bd4 Nd5 31. Rc5 Nb6 32. Rf5+ Ke7 33. Rxg5 Rc8 34. Rg7+ {Black resigned. This game was awarded a special prize. Accuracy: White = 59%, Black = 46%.} 1-0
