My memory suggests that the winning chances of a game against only the deuce point are something like 90%. So I played 15\/10.<\/p>\n\n\n\n<p>I was astonished to see BGBlitz considering this move a 0.085 blunder. And as I continued with my plan, my errors piled up to a loss of 0.23 equity, and my PR plummeted. In this situation, BGBlitz would have played 8\/6, 8\/5, voluntarily opening up the prime and giving white the chance to escape. And maybe hit my back checkers!<\/p>\n\n\n\n<p>If you think about the position longer, it becomes clear why in such a situation, letting go of the 6-prime makes sense. White has two checkers on the 2 point, and his own home board is crumbling. If he rolls a 6, I have good chances to hit either the blot that jumped past my prime or one of the blots on 2 and 1, and close my home board completely. In this situation my winning chances are even better than against a 2-point holding game. And should he hit one of my blots, the odds are still perfectly fine for me &#8211; he has to roll two 6, and a 6+1 to get his checkers out.<\/p>\n\n\n\n<p>So my plan was fairly sure to win, but by luring one checker away from the 2 point I can improve my chances even more. <\/p>\n\n\n\n<p>I was sure in such a position you can&#8217;t fail. Yes you can.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"724\" height=\"457\" src=\"https:\/\/gammonrants.org\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-22-111924.png\" alt=\"\" class=\"wp-image-636\" srcset=\"https:\/\/gammonrants.org\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-22-111924.png 724w, https:\/\/gammonrants.org\/wp-content\/uploads\/2023\/11\/Screenshot-2023-11-22-111924-300x189.png 300w\" sizes=\"auto, (max-width: 724px) 100vw, 724px\" \/><figcaption class=\"wp-element-caption\">BGBlitz 5-ply analysis &#8211; 6\/5 8\/5 is clearly the strongest move.
