This was one of the blindfold games Sijbrands played during his world record simultaneous blindfold of 28 games. Pieces 35 and 45 are not very active. White’s defence 44 / 49 / 50 is very solid. His other pieces are active. White occupies much more space than black.
Before playing 45.34 – 29 white should have improved the position of piece 31, by playing 45.31-26!

1) 45… 12 – 17 46.34 – 29 24 – 30 47.29 – 23! and white wins like in the game.

2) 45… 13 – 18 46.34 – 29 24 – 30 47.33 – 28 30 – 34 (what else?) 48.29 x 40 45 x 34 and instead of 49.50 – 45? 35 – 40! 50.44 x 35 12 – 17 = white simply plays 49.28 – 22 18 – 23 50.22 – 18! W+.

45.34 – 29 24 – 30
46.33 – 28 12 – 17?

Black could have escaped by playing a sacrifice: 46… 30 – 34! 47.29 x 40 45 x 34

1) 48.50 – 45 35 – 40!! 49.44 x 35 13 – 18!
50.28 – 22 will be met by 16 – 21! That’s why piece 31 is better at <26>!
50.31 – 26 12 – 17 51.49 – 44 14 – 19 52.44 – 40 16 – 21! 53.27 x 16 18 – 22 54.40 x 29 22 x 24 =

2) 48.31 – 26 12 – 17! 49.27 – 22 14 – 19 50.22 x 11 16 x 7 51.50 – 45 35 – 40
51… 13 – 18 is also drawing
52.44 x 35 13 – 18 and white cannot win.

47.29 – 23!

Now black is without a chance. White’s attack is unstoppable.

47… 13 – 19
48.31 – 26 19 – 24
49.27 – 22 14 – 20
50.22 x 11 16 x 7
51.23 – 18 30 – 34
52.18 – 13

After 52… 34 – 40 53.13 – 9 24 – 29 54.9 – 3 20 – 25 55.3 – 8 7 – 11 56.26 – 21 black resigned after more than 41 hours  of play…
