Section [8]: 3-fold
Diagram 8 shows the final position of game 5, where black offers a draw after white's 36th move. White had offered a draw a few moves earlier but after 36. bf4, treathening f47x, he practically forces it. First of all 36. ...-gh5?? allows a white win on blockade, as shown. Bushka positions are never too simple to lose!
Diagram 8
With gh5 out, black's only option is hf5, after wich white can attack the other man with fg4. Now the draw comes either way:
36. (bf4) | gf5 | |
37. fg4 | fh5 | Now the exchange is a clear draw (in as far as the game wasn't already). |
38. g46x | h57x | Draw. |
Alternatively:
36. (bf4) | gf5 | |
37. fg4 | fg5 | |
38. gf4 | gf5 | |
39. fg4 | fg5 | 3-fold!: white now can CLAIM a draw, because with 40. gf5 he can create the same position with the same player to move , for the third time: 36.bf4, 38.gf4 and 40.gf4. |
