whiteshark: "Leko, the tournament leader entering round 8 ran into some problems today against Jakovenko's Berlin wall.
White tried the new move <14. Rfe1>, but without any revolutionary ideas in the often seen ensuing position.
By the 20th move, the position was about even, and at this point, black began playing actively, grabbed the initiative, and secured some advantage. Soon, this pressure transformed into a pawn advantage, but the position was probably closer to a draw than a win.
How strange that the 50 move rule, which may be relevant in one out of a thousand games, has reared its head in consecutive games here in Jermuk. Had black been able to play <89...Rh2>, he would have won the a-pawn, and a win may have been likely, but with this move, he would have played the 50th move without a pawn push or a piece take, and thus was forced instead to play a5, and white maintained drawing chances.
Regardless, black attempted to win, but white held on to split the point."
