Key positions

3 positions from the day. Use the buttons under each board: test yourself first, then see what happened and the better move, or open the whole game up to that point. The red arrow is the move that was played.

The rook on a8 was left to the queen

Hanging pieces and moved defenders 21...Nc5?? Black, game lost Opponent rated 906

Clock: this move took 4.1 s, and 1:47 were left after it.

At move 21 Black was clearly ahead (+6.8), but White's queen had just recaptured on d5 and now attacked the rook on a8, which had no defender. 21...Nc5 did not deal with it, and 22.Qxa8+ won the rook (−5.8).

Black resigned after 22.Qxa8+. 21...Re8 moves the rook and keeps the lead (+6.8). The knight move took 4.1 seconds, with 107.4 seconds left.

After every capture by the opponent, ask what the capturing piece attacks now.

Taking the rook let the bishop escape with a capture

Missed tactics 22.gxh6?? White, game drawn Opponent rated 874

Clock: this move took 1.9 s, and 1:39 were left after it.

At move 22 the black bishop had just taken on f1, and the pawn on g5 attacked the black rook on h6. 22.Rxf1 takes the bishop back while the pawn still attacks the rook, and White stays clearly ahead (+5.8). 22.gxh6 took the rook first, and the bishop on f1 escaped with 22...Bxd3, taking the undefended white bishop (−5.7).

The capture took 1.9 seconds, with 99.1 seconds left. The game was later drawn.

When two captures are available, ask which enemy piece can escape with a capture of its own, and take that one first.

A free pawn in the rook endgame

Missed tactics 43.Ke6?? White, game drawn Opponent rated 874

Clock: this move took 4.0 s, and 37.8 s were left after it.

At move 43 the black pawn on e7 was attacked by the rook on a7 and had no defender. 43.Rxe7 takes it, and even though Black then wins the pawn on a6, White stays clearly ahead (+4.9). 43.Ke6 went for the same pawn with the king (44.Kxe7 followed), but Black first answered 43...Rxh2, and the endgame became level (+0.2).

The game was drawn by insufficient material. White had 37.8 seconds left after 43.Ke6, against 7.5 for Black before the reply. This was the second winning position in the same game, after 22.gxh6.

In a rook endgame, take a free pawn with the rook at once. A king walk to the pawn gives the opponent a free move.
