Johansen Loses a Drawn Position

Just got to Parramatta in time for the postmortem of Johansen - Sales. Pinoy chess fans will be glad to know that FM Jesse Sales has just defeated Australian grandmaster Daryl Johansen. In an error filled duel, Johansen actually had opportunities to draw, if not to win, the game.

And just before I left the venue a small argument broke out between Johny Bolens, who is playing in the major section, and the arbiter Charles Zworestine. Bolens seems to believe that the just published round 11 pairings for the major is completely wrong. He also made some rather controversial claims that we're not able to print at this moment.

Fritz gives 46...a5 as 2.19 advantage to black while g6 is considered equal at best.
