After an epic 248 moves, the fourth, final and deciding game in the Zurahn-Rybka match has resulted in a draw. The most moves played in a tournament game was Nikolic vs Arsovic for a 269 move draw and that was only because the 50 move rule was at the time a 100 move rule. What's ridiculous is that the game was drawn after 40 moves, but because I couldn't get Rybka to go for threefold repetition (it sees itself as ahead but there's no way to advance, so the game long-term was actually drawn) I tried to reach the 50 move rule, which is that if there have been no captures or pawn moves in the previous 50 moves, a player may claim a draw. After 49 straight moves without a capture or pawn move, Rybka moves a pawn. Then after another 40+ did it again. Eventually it ended in insufficient material. My analysis of the opening was very accurate, still working out that I couldn't find a winning line. I'm very interested now in following the line of 1. e4 c5 2. Nf3 d6 3. Bc4 because of just how difficult it is to get any counterplay. The Sicilian is the most popular opening, which is initiated by black so it can't be outright losing. Java HTML/JS Rybka wins the match by a score of 2½ - 1½. I finished with an outing of +0 -1 =3.
