67:, professional shogi players will have to immediately play a subsequent game (or as many games as necessary) with sides reversed in order to obtain a true win outcome. (That is, the player who was White becomes Black, and vice versa.) Also, depending on the tournament, professional players play the subsequent game in the remainder of the allowed game time. Usually there is a break time period between the replay games.

sennichite sequence in that Black's rook like the previous gold cannot capture White's bishop on 79 and also is pinned by the same bishop.

sequence via 64.S*82 Gx82 65.Nx82+. And, since White does not have any checkmate sequence available to him, after this, Black will have a mate-in-one with +N83 (or G*83 or R*83). Thus, White must defend against the brinkmate by creating another threatmate against Black with 63...Gx88. This threatens

After White's gold is removed, the board position is very similar to the position at after the 123rd move (the first diagram shown above). The only difference is that instead of Black having a gold on the 88 square Black has a rook on 88. However, this is sufficiently similar to force Black into a

After 66...G*89 67.G*78 Gx88, there is a second repeat of the position at move 130. After 68.Gx88 G*89 69.G*78 Gx88, there is a third repetition. And, after 70.Gx88 G*89 71.G*78 Gx88, White makes the fourth repetition leading to sennichite. After this, according to professional shogi rules, a new

4099:
After these eight moves, we have a near identical position to the position after the 122nd move (62. Px66). However, there is a small difference in that now White has a rook in hand instead of the two golds and Black has a gold in hand instead of two rooks. Thus, although very similar (and

After this, White started setting up the repetition sequence starting with 62...G*89. Dropping the gold to the 89 square puts Black in his own threatmate situation as White is threatening the mate-in-one 63...Bx88+ on his next move.
1735:
Therefore, Black defends the 88 square in the only way he can by dropping a rook to the seventh file (63.R*78). He cannot remove White's gold with his own gold on 88 (63.Gx89) since that gold is

Similarly, White captures the rook on 88 with their gold creating the same threatmate as above (65...Gx88). It is here on the 130th move that the sennichite sequence technically starts.
