Turnarounds, missed chances
A “fast-classical” time control is in place at the Grenke Chess Classic in Karlsruhe, with 45 minutes for the game and 10-second increments per move. After four rounds of play, it is apparent that this format allows both for interesting theoretical battles and tense-filled tactical sequences (which might lead to game-losing blunders). Naturally, it also tends to deprive us of accurate endgame play or long, intricate middlegames.
Rounds 3 and 4 of the event featured three major turnarounds.
Daniel Fridman survived a clearly losing position before turning the tables and beating Maxime Vachier-Lagrave in round 3.
Vincent Keymer misplayed a winning pawn endgame and thus failed to convert his clear advantage against world champion Ding Liren in round 4.
Magnus Carlsen had an extra piece against Vachier-Lagrave, but a single misstep with his knight gave away his advantage, and the round-4 game ended in a draw.
In this course, we will learn how to identify passively placed pieces in any given situation and how to improve their health by bringing them into active squares.
The one player who has managed to avoid making big mistakes is, consequently, the sole leader: Richard Rapport. The Romanian representative scored 1½ out of 2 on each of the first two days of action and now has a 1-point lead over Carlsen, Ding and Keymer.
On Wednesday, Rapport played with the white pieces twice. First, he drew Keymer after getting a slight edge in the middlegame. Then, he took advantage of an early blunder by Fridman to get a 25-move victory.

14...Qc715.Qxd6Qxd616.Rxd6Ne417.Rd7Nxc318.bxc3Rfd8Black has sacrificed a pawn, but he has a much better pawn structure and his knight is far superior to his opponent's bishop.19.Rxd8+Nxd820.Be2Kf821.Rd1Ke722.Rd5f623.Kc2Nb724.Kb3Nc5+25.Kb4Rd826.a4Ne427.f3?!Better was27.Rxd8Kxd828.c5!Nxc529.a5White has given back his extra pawn, but freed his bishop - this is a position White should not lose.27...a5+28.Kb3Nc5+29.Ka3Rd630.Bd1Na631.Bc2Nc732.Rxd6Kxd633.Be4Na634.g4?This weakens White's position too much and gives Black the opportunity for a marvellous double pawn sacrifice.More solid was34.Kb2and there is no sign of Black wanting to make any progress.34...Nc535.h4

50...Qf5As in the variation with 44...Kg4, Black turns his pawn into a queen one move earlier. But since Black cannot enter the square b5 with his queen, the position is drawn. In the line with 44...Kg4 Black could calmly exchange queens and then collect the white pawns on the h-file. But with the king on e4 he doesn't have the time.51.Kb7Qd752.Kb8Qd653.Kb7Qd754.Kb8Qxa4Keymer makes one last attempt and enters the queen endgame. But here Black can save himself by perpetual check.55.c8QQd456.Qg4+Kd557.Qd7+Ke458.Qg4+Kd559.Qd7+Ke4A game well played by Keymer, which in the end led to a bitter draw due to a study-like save by White.½–½
