What this reveals though, is that Viswanathan Anand is now at the point where his win chance stems as much from forcing a tie-break as from winning outright. Both models give the players an even chance of winning a tie-break, which is one reason he has such a good chance from that. Both models find it most likely that Carlsen will win the match in Game 11.
