Original screenshot
Suggested moves come from one model evaluation, without search.
Experimental. The list is the model's first instinct about the position, read once: it does not look ahead at any continuation, and it can be wrong. Each percentage is the model's own preference among its moves, not a win rate or a measure of how good the move is. Selecting a suggestion plays it into your branch; it never changes the imported SGF.
Should the engine answer as White?
After each of your moves on this board it plays one move back, as Play's opponent does at the level you choose.
Tap an empty point to branch from the position on screen. Moves alternate normally and obey captures, suicide and simple ko. For an ordinary game SGF, Continue in Play saves the line on screen as a normal Hoshi game, where it can be played, scrubbed and branched again. SGFs with setup stones stay here because Play cannot represent that setup.
Bring in a whole board from a screenshot or SGF. Scrub through the game, try a branch, and see the local model's suggested moves. This is separate from 사활 helper: it does not give an exact life-and-death verdict.
Import a whole-board screenshot or an SGF to begin.
Your imported games
Opening one brings back its board, its moves, the position you were looking at and the branch you were exploring. Kept on this device and in this browser only: not synced, not backed up, and not part of your Play games or your 사활 problems.
Engine model
Each imported board loads a model automatically: the one saved on this device — Play's review models included — that fits its size, preferring one validated there. Choose a file only to use a different model for the board on screen. Nothing here replaces the opponent or review model used on Hoshi's Play page.
