With 40K visits, not a single playout went into the snapback move T18 S16. You can confirm next move the visit count in tree and # of playouts are the same, so tree re-use after this move is 0.\r\n\r\nSince the snapback play to capture would be an illegal move if you couldn't do the capture, I wonder if training illegal moves as 0% search targets could push snapback moves down that low as well? Assuming the issue isn't something else and not actually snapback/illegal move related.\r\n\r\nIt just seems odd to me with 39K+ visits, not a single playout was spent on the obvious group capture."},"comment":{"url":"https://api.github.com/repos/gcp/leela-zero/issues/comments/371316429","html_url":"https://github.com/gcp/leela-zero/issues/877#issuecomment-371316429","issue_url":"https://api.github.com/repos/gcp/leela-zero/issues/877","id":371316429,"user":{"login":"WhiteHalmos","id":593472,"avatar_url":"https://avatars0.githubusercontent.com/u/593472?v=4","gravatar_id":"","url":"https://api.github.com/users/WhiteHalmos","html_url":"https://github.com/WhiteHalmos","followers_url":"https://api.github.com/users/WhiteHalmos/followers","following_url":"https://api.github.com/users/WhiteHalmos/following{/other_user}","gists_url":"https://api.github.com/users/WhiteHalmos/gists{/gist_id}","starred_url":"https://api.github.com/users/WhiteHalmos/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/WhiteHalmos/subscriptions","organizations_url":"https://api.github.com/users/WhiteHalmos/orgs","repos_url":"https://api.github.com/users/WhiteHalmos/repos","events_url":"https://api.github.com/users/WhiteHalmos/events{/privacy}","received_events_url":"https://api.github.com/users/WhiteHalmos/received_events","type":"User","site_admin":false},"created_at":"2018-03-07T23:00:46Z","updated_at":"2018-03-07T23:00:46Z","author_association":"CONTRIBUTOR","body":"@roy7 Why don't you try averaging 2-4 or even all 8 heatmaps for your RoyalZeroSlow bot?
