HolIgor Explores Yose Problem 3
Keywords: EndGame, Problem
This position in quite typical. The problem is not only to find the value of the move but to find the best moves. This makes the calculations more difficult.
White 1 make the situation quite complicated because black's connection makes white play sente. So, the problem is reduced to the next subproblem.
Black first. Connection produces the score of <3|2> . If White plays first and white is a ko monster then the position reduces eventually to
The score is <0|5> The record of the yose game is B(7,1)( |1><0| + |0><1|) + W(0,0)(B(3,2) + W*(0,5)) The averaging should start from the deepest. B(7,1)( ( |1><0| + |0><1| ) + W(0,3)(|2><0| + |0>?<4|) = 1.5 + |4.5><0| ( |1><0| + |0><1| ) + |0><4.5| (|2><0| + |0>?<4|) Thus, the value of the move in this position is 4.5 .
