1.33-29 17-22 2.39-33 11-17 3.44-39 6-11 4.50-44 1-6 5.31-26 Although he hasn't been very successful with it so far, Georgiev sticks to his opening choice with white. 16-21 6.32-28 19-23 7.28x19 14x23 8.35-30 10-14 9.40-35

With his last move Georgiev deviates from earlier games in the match where he played the usual 9.30-24.

14-19 10.44-40 20-25 11.30-24 19x30 12.35x24 21-27 13.37-31 13-19 An interesting alternative was 23-28 14.42-37 5-10 But perhaps Schwarzman feared an openings study by his opponent.

14.24x13 8x19 15.41-37 9-13 16.49-44?! It seems an early decision to already develop this vital piece on 49. But probably white has to do it anyhow in the near future.

19-24

With this backwards exchange Schwarzman makes clear he doesn't believe that black can profit from the missing piece on 49. Nevertheless it is interesting to investigate what could happen if black had kept the pieces on the board. For example 11-16 17.37-32 15-20 18.32x21 16x27 19.42-37 4-9! 20.37-32 (note that white cannot afford to wait with this move) 23-28! 21.32x14 13-19 22.14x23 27-32 23.38x27 20-24 24.29x20 18x49 25.27x18 12x23 26.34-29 23x43 27.48x39 25x14 28.40-35 49x40 29.45x34 with a position that looks about equal.

17.29x20 25x14 18.37-32 5-10 19.32x21 22-28 20.33x22 18x16 21.46-41 14-19 22.41-37 10-14 23.38-33 12-18 24.37-32 7-12 25.34-29! 23x34 26.40x29

Georgiev increases his influence in the center, and wins some terrain with the last exchange. That is a good strategy to compensate for the weak corner piece on 26. The position is now perfectly in balance. During the next abstract phase of the game both players spent a lot of time to find the right strategy. Schwarzman patiently waits until Georgiev has made some decisions before he reveals his plans and enters the 5th row.

14-20 27.42-38 2-8 28.47-42 3-9 29.45-40 9-14 30.40-34 19-24 31.32-28 14-19 32.38-32 20-25 33.29x20 15x24 34.42-38 18-23 35.31-27 17-21 36.26x17 11x31 37.36x27 12-17 38.48-42 8-12

A classical position has emerged in which Schwarzman has slightly better opportunities due to his control over both wings.

39.42-37 17-21 40.37-31! Georgiev takes drastic measures to avoid any surprises after the normal classical development 40.44-40 6-11 41.40-35 12-18 That seems a right decision, since white has to operate carefully in this position: 42.34-30 (not 42.28-22? due to 24-29! 43.33x24 19x30 44.35x24 23-28 45.32x12 21x41 with opportunities for black) 25x34 43.39x30 23-29! 44.43-39 (not 44.28-22? 18-23! 45.33-28 21-26 46.30-25 29-34 and white is in trouble) 29-34 45.28-22! (not 45.30-25? 34x43 46.38x49 11-17! and again white is in trouble) 34x43 46.38x49 and a draw is the most logical result.

13-18

An interesting but questionable move for black was 24-30!? Then white can not play 41.33-29? due to 12-18! 42.31-26 4-9 43.26x17 18-22 etc. And after 41.31-26? 12-17! white is lost since after 42.27-22 4-9 43.22x11 6x17 44.44-40 30-35! he is the victim of a terrible 'zugzwang' and after 42.44-40 30-35 43.27-22 black has an elegant combination: 35x44 44.22x11 (or 44.39x50 25-30! 45.34x25 19-24 46.28x8 17x48 47.26x17 24-30 48.25x34 48x2 B+) 16x7 45.39x50 25-30! 46.34x25 23-29 47.33x24 19x30 48.25x34 7-11 49.26x17 11x42 B+. But of course white will play 41.28-22! instead.

41.31-26 12-17 42.44-40 4-9 43.40-35 9-14 44.34-30 25x34 45.39x30 23-29 46.30-25 29-34 47.43-39 34x43 48.38x49 17-22

Also possible was 18-23 49.49-43 23-29 50.43-38 29-34 51.27-22 34-40! 52.22x11 16x7 53.35x44 24-29 54.33x13 7-11 55.26x17 11x42 with a draw.

49.28x17 21x12 50.49-44 6-11 51.44-40 11-17 52.33-28 18-23 53.27-22 23-29 54.22x11 16x7 55.32-27 7-11 56.27-22 12-18 57.22x13 19x8 58.26-21 8-12 59.28-22 29-33 60.21-16 33-38 61.16x18 38-42 62.18-12 42-47 63.40-34 47-41 64.12-7 14-20 and finally the players agreed to a draw.
