Match Play. Red trails 0-6 to 11. How should Red play 61?
An initial 3-ply evaluation criticises 22/16*, 6/5 but the rollout gives top billing to three plays: 22/16*, 6/5; 13/7, 8/7 and 13/7, 6/5.
The first play has the advantage of helping Red’s timing by releasing a checker although it may help White’s timing as well.
Some positions are just too difficult for humans to get exactly right and even the machine struggles. So, take your pick from the three plays above.
