Round 10, Switzerland against Bosnia and Herzegovina, a match the team needed to steady after 1 to 3 against Serbia the day before. Colin Federer sat with Black on board four against FM Ismet Mesic, close in rating, and one of the two match points the day was pointed at. Bänziger had already won on board three, Bogner and Peng on boards one and two were still in play. A half point on board four holds the board and keeps the match mathematically alive.
The opening turned into the Exchange Variation of the Queen’s Gambit Declined, the Reshevsky Variation: a structure in which White plays the minority attack on the queenside and Black holds the centre. What followed was a game without disaster and without breakthrough, four spots where the objectively best move was not on the board, and one spot where White himself let the tension go. At the end a knight ending and a repetition on move forty-five. After three rounds in which the clock had backed Federer into a corner, it stayed outside this one: twenty-four minutes still on the clock at move forty.
The pawn move no piece needed: 17...g6
White had just pulled the knight back from e2 to c1, a manoeuvre that keeps Nb3 to c5 or Nd3 open and threatens nothing at the moment. Black had every piece developed, the rooks stood on a8 and e8, and the question was simply where the queen and the bishop on c8 should go. keeps the queen flexible in the centre and covers the pawn on d5, develops the bishop and connects the rooks. Both are simple, good moves, and objectively of equal strength.
The move played was , a quiet pawn move with no concrete purpose. Objectively it is a small inaccuracy, about a third of a pawn: an equal position becomes one with a small edge for White. Practically it is a cautious move that gives the king air and later opens g7 for the knight on h5. It just does not carry with it anything that needed this pawn to move right now.
The rule behind it is not a difficult one, it only gets forgotten a lot: in a quiet position with no concrete threat, the move belongs to a piece that is still looking for a square, not to a pawn that locks in a structure. Pawn moves are decisions that cannot be taken back later; piece moves usually can.

The queen trade declined: 19...Qe6
White had put the queen on c5 and attacked the black queen directly. Objectively best was , an endgame Black has to hold with active knights against a white pawn on c5. Level, but work for both sides.
Colin Federer sat almost fifteen minutes over the position and chose , the retreat that keeps the queens on the board. Objectively it is a small inaccuracy, about a third of a pawn, and yet a move a coach hesitates to fault on a team match board. The opponent had no plan at this point beyond trading queens, and someone who has no other plan rarely gains anything from a queen trade.
Two moves later White tried it a second time with , and again the queen went to e6. After that White pulled back to c2 and switched plans: the rooks came to the a-file. Objectively the trade was the better path. Practically the second path was the easier one. The rule behind it is one for team matches: when you are looking for the half point, you do not give up complications for an endgame in which you have to play accurately for two hours.

The simplification that took the edge: 28.Rxa8
Two moves earlier Federer had played , the knight from h5 to a passive square, instead of , the active move that forces the white bishop to trade and clears the queenside at once. It was a drift from a small half pawn to three quarters, still not a lost position, but the clearest chance to equalise Black gave up here.
that followed was the best move in the position: it forces the white bishop on d3 either to trade or to leave the h7 to b1 diagonal. A clean defensive move in a not entirely easy position, and played without spending time.
The move the position asked for is , a position where White has the passed a-pawn and stays about half a pawn ahead. What was played was , and with the rook trade the white advantage shrank to something like a fifth of a pawn. It was not a draw yet at that moment, but it was the transition into a position where Black no longer had anything concrete to defend. FM Ismet Mesic had a small edge and chose the move that heads fastest into an endgame, not the one that carries the edge forward. That is how a game without a mistake tips into a draw: not through a blunder, but through a simplification that takes the better side’s chances off the board with it.

Two knights hold the ending
After all the exchanges of the last fifteen moves the endgame was on the board: White with knight and bishop, Black with two knights, equal pawns, no isolated pawn, both kings on the way to the centre. The black knight on b8 covers a6 and d7, the knight on b6 covers a4, c4 and d5, and none of the combinations of Nb7, Nc5 and Kd3 gets past either. The white bishop on f5 is the strongest piece in the endgame, but it has no weakness in Black’s camp to lean against.
On move forty-one the repetition began: . The white knight looks for a combination between b7 and c5, finds no move from either square that wins material or overloads a square, and the black king comes back each time to a square where nothing attacks it. After the third repetition the game is called drawn.
The rule for this is one of the elementary ones of the endgame: with equal material and a symmetric structure it is enough that one side has the defending pieces on the right squares. Two knights on b6 and b8 are enough guard against a bishop plus knight plus king; and when the opponent has no weakness to press on, a half point is no longer a question of time but a question of composure.

Verdict
Half a point on board four with Black against an opponent close in rating, in a game without an obvious mistake but with four spots where the objectively best move was not played: instead of a piece move, the queen trade declined twice, and on move twenty-six the knight to g7 instead of to c4. None of these was a blunder, none of them was objectively the strongest, and the position still held, because on move twenty-eight White himself let the tension go with Rxa8 instead of carrying the edge forward with Nf4. From there it went cleanly: the queen trade on b7, the knight manoeuvres, the king walks, and the repetition on move forty-five.
After three previous rounds in which Colin Federer had drifted into time trouble, the clock stayed outside this one: no moment below roughly twenty-four minutes, four and a half hours long. For the team the half point on board four is the minimum you look for from a Black board against a near-equally rated opponent, and in a match where boards one and two were still unresolved, it was the stable side of a day whose result was still open.
