7/20/2015 – Three hard fought games to start the tournament in Biel. The only winner, however, was Michael Adams over David Navara in a long opposite colored bishop endgame. MVL, the defending Champion, was unable to break through Pavel Eljanov's Berlin Defense. Lastly, Wojtaszek definitely let go of a very clear advantage against the always eccentric Richard Rapport and his Chigorin!

Round 1 report by Daniel King
A hard fought first round in Biel, though we only had one decisive result. The game between Adams and Navara was the last game to finish, and it was only near the end that the Czech player let go of the draw:
Adams, Michael 1-0 Navara, David
Adams played a great game and obtained a winning endgame with opposite colored bishops and queens, but he was not very precise in a key moment:
25...Kg726.Bf1White has obtained a very nice endgame. The pawn on b5 cannot be defended, and Black is not in time to create real counterplay.Qc727.Qe8Bf628.Bxb5Qxc329.Bc6!Material is still even, but the b-pawn is passed and Black's king is weak, for now b4 is untouchable.Qf329...Qxb430.Bd5and the kingside falls, starting with f7.30.Qd7!Very accurate! 30.Bd5Bxh431.gxh4Qg4+is nothing more than a perpetual.30...g531.hxg5?Almost ruining the game.31.Bd5gxh432.Qxf7+Kh633.Qf8+Kg634.Bf7+!Kg535.gxh4+!This move is surprisingly tricky to find when analyzing quickly.Kxh435...Kf436.Be6!And this move is VERY tricky to find when analyzing quickly! It is the only winning move!36.Qh6+Kxe4 doesn't work.36...Kxe436...Qd1+37.Kh2Kxe438.Qxf6and the game is over.37.Bd5+Kxd538.Qa8+skewers the queen.36.Qh6+Kg437.Qh5+Kf438.Qf5#31...Bxg532.Qxd6This endgame is not easy to evaluate. Clearly White is pressing for a win, but making progress is not trivial. Black will have a decent blockade on the darksquares and it is unclear that trading queens is a good or bad thing for Adams.Qc333.Kg2Qb234.Qc5Qd4The computer recommendation, but is the endgame a draw?35.Qxd4exd436.f4Be737.b5Bc538.e5d339.Be4d240.Bc2Everything has been basically forced since the queen trade up to this point.f640...h6looks more logical to me. I don't think giving White a passed pawn is a good idea.41.exf6+41.e6f5simply loses the e-pawn.41...Kxf642.Kf3h543.Ke2Bd643...Bb6!44.Kxd2Bf245.Ke2Bxg346.Kf3Be147.b6Bb448.b7Bd649.f5the two passed pawns being so far apart from each other looks dangerous, but I can't imagine any way of making progress for White.44.Ke344.Kxd2h445.gxh4Bxf4+is a dead draw, as White has the wrong bishop for his h-pawn.44...Bc7?44...Bc5+45.Kxd2Bf2=45.Bd1!h445...Bb6+46.Kxd2Bf247.g4hxg448.Bxg4is winning.46.gxh4Kf547.Bc2+Kg448.Ke4very importantly, White preserves his f-pawn. Now the rest is easy.Kxh449.Bd1!Black's king is cut off! A deadly zugzwang.Bd850.Kd5Kg351.f5Kf452.Ke6Ke453.Bc2+Kd454.Kd7Bb655.f6Kc356.Bd11–0
Wojtaszek, Radoslaw ½-½ Rapport, Richard
The only predictable thing about Rapport's openings is that they are completely unpredictable. He chose the Chigorin Defense today, not a common guest in grandmaster games. Wojtaszek, not surprisingly, obtained a crushing position from the opening, but he let his opponent go:
Rapport's chess is as weird as always!

Vachier-Lagrave, Maxime ½-½ Eljanov, Pavel
An interesting Berlin, in which both players tried to restrict their opponent's pawn advances. Eljanov won a pawn, but did not gain an advantage: MVL's pieces were very well positioned and a draw seemed likely. The Ukrainian even pushed a little too much, but it was always a draw:
