FIDE Candidates - Finals Round 4

One decisive game today with Rublevsky defeating Krischuk with the Scotch to tie their match.  Bareev failed to make a dent in Leko's comfortable lead and now must win both remaining games to take their match to tie-breaks.  Kamsky succeeded in blocking the position to keep Gelfand at bay.  But Kamsky's last White of the match is tomorrow and he needs to win to level the score.  Shirov obtained excellent winning chances against Aronian, but despite being 2 pawns to the good, he frustratingly let the game slip away to a draw.

Games below.
