2017 3 Tables - July Round 1 
NM Mark Schwarz, 1950 - Anton Taylor, 2007
Caro-Kann: Classical (B18)

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Bf5 5. Ng3 Bg6 6. Nf3 Nd7 7. Bd3 h4 first is more common. 7. ... Bxd3 8. Qxd3 e6 9. O-O Ngf6 10. Re1 Be7 11. c4 O-O 12. b3 Bf4 is worth considering as well. Maybe even a little better but things are equal. 12. ... c5?? Things are in an uncomfortable equilibrium with a slight advantage to white. breaking things open at this moment can only give something for white to work with. Komodo gives moves like Re8, Qc7, or a5 or even worse some moves like Bd6 moving the same piece twice. 13. Bb2? d5 expanding in the center gives white an advantage but this move keeps things in that odd equal place with white only slightly better. 13. ... cxd4 14. Qxd4 Bc5? No development. I thought maybe the attack on the f-pawn would pay off but there are no concrete variations to back that up. Qb6 or Qc7 are better. 15. Qh4 Qb6 16. Re2 a5? I made light in my mind of the kingside threats from white. This doesn't lose but the threat it generates is too slow. Rfd8 or Rad8 is komodo's recommendation at 20 ply depth or so. 17. Nh5 Nxh5 18. Qxh5 Nf6? Had I seen the crushing reply I would have played komodo's recommendation ... f6 instead keeps things together and safe. 19. Bxf6 gxf6 20. Ng5 fxg5 21. Qxg5+ Kh8 22. Qf6+ Kg8 I assumed that Mark would take the draw opportunity because I did not see a forced win. A piece down he should either see a direct winning method or settle for the forced draw. 23. Re4? Wins for Black. Rfd8 24. Rg4+ Kf8 25. Rg7 Qc7 26. Rxh7 Ke8 27. Re1 Qe7 28. Qf3 White backing up like this is a sure sign that black must be winning. 28. ... Bd4 29. Re4 Qf6 30. Rf4? This leads to a crushing response. 20. ... Qg6 31. Qe4 Be5 32. g3 Bxf4 33. Rh8+ Ke7 34. Qxb7+ Kf6 35. Rh4 Bg5 36. Rg4 Qf5 37. h3 Be3! The quickest end is returning the piece. 0-1
