- #6
- At position #6 it was stated that if
- White has to move here then he must
- retreat. But where should he go
- to?
[Next]
- Note that moving just straight back
- like this loses the game. Now
- Black can play ...
[Next]
- Ke5 gaining the opposition and
- forcing White to move left or right.
- Black will advance his king to
- the other side and win like the
- following ...
[Next]
- ... position which is a win for
- Black.
[Next]
- #6
- So at position #6 where should
- White move to?
[Next]
- Moving to c3 or e3 first ...
[Next]
- ... will allow ...
[Next]
- ... the king to regain the opposition
- and force Black to retreat. Note
- that White chose to take 2 moves to
- get his king to the d3 square instead
- of just doing it in 1 move. In
- effect he was trying to lose his turn
- to move so that he can force the
- Black king to retreat. This
- process moving from d4 to c3 and then
- to d3 is called
- triangulation because
- the king has formed a triangle by
- moving through 3 squares.
[Next]
- With Black to move he will have to do
- the same thing if he wants to hold a
- draw.
[Next]
- The king advances. There isn't
- time to try to penetrate by way of
- the h-file.
[Next]
- Now Black has done the same
- triangulation to force the White king
- back. Neither side can make any
- progress so the game is a draw
- (tie).
