Black mates in 27 moves with best play (Nalimov tablebase).

Kf1 Bh2

Black has taken far too long to reach this position: only 19 moves remain before the 50 move rule kicks in, and with best play, it is 17 moves to mate.

126. Ke1 Ne4 127. Kd1 Bg3?

Now it's 5 more moves to mate, and with best play the win is gone. 127... Ke3 is simplest.

128. Kc2 Ke3 129. Kb3 Nd6 130. Kc3?

This moves the win in 11 moves with best play, and Black would mate 48 moves after the last capture. 130. Kb4! was the unique move to preserve a draw with best play.

130... Be1+ 131. Kb3 Kd3 132. Ka4 Bc3 133. Kb3 Nf5?

This loses two moves; now Black mates on the 50th move (and still wins) with best play. The best move is 133... Ne4.

134. Ka4 Nd4?

This loses one more move, and now with best play it's a draw under the 50 move rule. The only move to preserve the win is 134... Kc4.

135. Ka3 Kc4 136. Ka4 Be1 137. Ka3 Kb5 138. Ka2 Bb4 139. Kb2!

(Only move.)

139... Kc4 140. Kc1 Kd3 141. Kd1 Ke3 142. Kc1 Ke2 143. Kb1 Ba3 144. Ka2 Bc1

That's it! White could have claimed a draw here.

145. Kb1 Kd1 146. Ka2 Kc2 147. Ka1 Ne2 148. Ka2 Nc3+

1/2-1/2
