Strategic draw
If black has a king and a piece things get more complex. Black holds the main diagonal 46/5. White has to conquer this diagonal to be able to bring more pieces to king. In this position white’s goal will not be achieved. He can’t chase black’s king from the main diagonal.
Possessing two kings white will succeed in chasing black’s king from the main diagonal.
Black to play doesn’t have a good move.
At 41, 37, 32, 28 or 23 white catches the king by 15 – 10! 4 x 15 (if the king takes 20 - 14 + follows) 24 – 30 15 x 24 35 x 46 +.
Squares like these, not at the edge of the board, are called wild squares for the king.
If white is to move he plays 1.15 – 10! 4 x 15*
2.35 – 49 (black’s king can’t go to a wild square because of 24 – 35 +) 46 – 5 3.49 – 44 5 – 46 4.44 – 35 and black has no safe square for his king anymore.
Tag 15 / 25
Black can draw this position if he succeeds in changing one of his pieces. With only 3 pieces left white can’t win theoretically.
Black’s piece at 15 is a problem for white. It opposes piece 25, so there is a threat 15 – 20 25 x 14 46 x 5 drawing the game. The position 15 / 25 is an example of a tag.
White tried to stop the exchange 15 – 20.
1.50 – 33
Now at 15 - 20 white takes with his king 33 x 15.
1… 6 – 11!
2.33 x 6 15 – 20
3.25 x 14 46 x 5
Usually a draw is agreed in such positions.
If white still wants to play for a win you have to remember an important rule:
☼ Being in a situation having 3 pieces of which at least one is a king, the game is a draw after 16 mutual moves.
In this situation black holds the main diagonal. In such a case the chance of winning is very small.
You should be aware of some standard tricks.
Black to move is faced with the threat 47 – 33!
44 x 46 10 – 5 W+
44 x 5 37 – 46 +
Black to move should go to the other side of the main diagonal, for example square 11. However, in several games black was trapped:
1… 44 – 22?
2.37 – 31! 22 x 36
3.10 – 4
Black’s king is locked!
White can force a draw.
An immediate attack by 49 – 27? is losing because of 15 – 20!! B+.
1.25 – 20 15 x 24
2.49 – 27 45 – 22
3.27 – 32 22 – 28
4.32 – 27
Black can’t do anything else but defend the piece with his king. After the moves have been repeated for three times white can claim a draw.
White has refused to sacrifice her piece at 25 for a long time already. This is very dangerous! Still white was reluctant to give up the piece.
1.6 – 1 15 – 33
Now sacrificing the piece is obliged. But white refused to do so.
2.1 – 6?? 33 – 22!
White surrendered.
