[Game log #100]
Here's the game between Okisato and Xiu featured in Chapter 159. It's a fog of war chess match, meaning the board is covered in a thick fog, making it unable for players to see their opponent's pieces. The only way to do so is to make use of each piece's vision range. For example, pawns can only see 1 space ahead, knights can see the spaces they could jump to, bishops can see the full diagonal unless an opponent's piece was blocking a square. The same was true for rooks and queens, which can see all the squares they could move to respectively, and would only have their vision obscured if a piece was blocking a square. Due to the state of the game, capturing the king, instead of checkmating it, is the only way to win the game. It is also impossible to capture any piece shrouded by fog, even if a piece was capable of moving to that square. Only pieces that could be seen, can be captured.
I don't know if there is a fog of war analysis engine, but just in case, here's the full game log. This includes all the moves that were performed, but unable to be seen by Okisato in the chapter. I also feel it's noteworthy to note that Xiu was in fact moving and capturing pieces with her feet. Note that the R on move 17 stands for "resign".
Following the revisions, this is now the 100th Game log in the series, even though there have technically been more than 100 individual games played in it.
