5th round preliminated
Xakru-Fredi_z
After 34…b4-b3

The engines insist on 35.f4 but this move weakens irreparably e4 and g4 squares and leaves white with only tiny chance of survival. Again, Jiri, in defence of strong 35.h4! that was actually played, mentioned the distrust of engines for h and a pawn moves. Roman was fairly easily convinced and the game saved later on after: 35….

 6th round preliminated
Averell-Xakru
After 27.Be2xc4

When choosing between Nc4 and Rc4, Jiri correctly stressed less than perfect play of engines in positions with bigger pawn disparities. In this case, taking with rook is even objectively stronger and its quite suprising that engines show certain difficulties to reach the same conclusion. In any case, we played 27…Rc4 and won after  28. fxg5 Rxb4 29. Bxb4 Nc6 30. Bc3 Re7 31. Re1 Kf7 32. Kf2 Ke6 33.h4 Rd7 34. g4 Rd5 35. Re3 b5 36. Kg3 a5 37. h5 b4 38. axb4 axb4 39.

3th round Final
Icy45-Xakru
After 22.b2-b4

In the game with icy45, white made in much worse position rather successful attempt to change the the course of the game with tricky move 22.b4!. How improbable it may seem, with the normal course of the game white would already get a very reasonable position in connection with f4 break and overall impossibility of black to regroup his pieces in a way that would allow for any winning attempts. Therefore, we after a 15 minutes thought, we decided to return a pawn and go into the better knight ending. As a "Buchholz" for that decision, Jiri´s remark about weaker understanding of Rybkas for that type of endings was again very useful and -which is even more important- proved correct after 22...axb3 23. axb3 f5 24. Bg2 Kf7 25. Nc4 Rxa1 26. Rxa1 Ke6 27. Ra7 Rc8 28. Bb7 Nc6 29. Bxc8 Nxa7 30. Bxd7+ Kxd7 31. Nxe5+ Kd6 32. Nf3 Nc6 33. Nh4 Ke6 34. Nf3 g5 35. Kf1 g4 36. Nd2 Kd5 37. Ke1 Kc5 38. Kd1 Kb4 39.

 In general, there were frequent situations in the tournament where human experience made the engines to change their taste and evaluation gradually. To name them all, it would require from us extensive research that would have to conduct on ourselves. Thats why we will stick with this three examples.
