Came across this position yesterday. I was doing great, trapped three checkers of my opponent behind a six prime. Now how to finish him off?<\/p>\n\n\n\n

My game plan was simple: keep the perfect 6 prime as long as I can, add remaining checkers to the prime, hit the checker on 1 until I have a 6-prime and he only has checkers on the two point, then bring the game home. 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

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

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 – he has to roll two 6, and a 6+1 to get his checkers out.<\/p>\n\n\n\n

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

I was sure in such a position you can’t fail. Yes you can.<\/p>\n\n\n\n

BGBlitz 5-ply analysis – 6\/5 8\/5 is clearly the strongest move. Mine 0.085 worse.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"
