Diwa King: Why Capturing One Attacker Does Not Stop Double Check

Follow a complete six-piece chess position: two checks arrive together, two tempting replies fail, and Durga Maa is asked for courage to see the whole danger.

Your rook seems able to take the checking bishop. You reach for it, then notice the second attack: a white rook is looking straight down the file at your king.

This Diwa King chess exercise begins with six pieces on an otherwise empty board. Use the usual coordinates, with a1 at White's bottom-left corner. White has the king on g1, rook on e1 and bishop on e2. Black has the king on e8, rook on b8 and bishop on f8. White moves next.

One bishop move, two checks

Move White's bishop from e2 to b5, along d3 and c4. Two lines now reach the black king:

The bishop attacks e8 along b5–c6–d7–e8.
The rook attacks e8 up the open e-file from e1.

The bishop's departure uncovered the rook. Both pieces are checking the king at the same time: double check.

Before deciding what Black should do, trace both lines with a finger. Do not remove either attacker yet. The danger that is easier to see is not the only danger that must disappear.

Try the tempting rook capture: move Black's rook down from b8 to b5 and take the white bishop. The diagonal attack has gone, but the white rook on e1 still attacks the king on e8. Black's king remains in check, so that reply is illegal.

Now restore the position after the bishop move to b5, written Bb5 in chess notation. Try moving Black's bishop from f8 to e7. It blocks the e-file, but the white bishop still attacks along b5–c6–d7–e8. That reply is illegal too.

The FIDE Laws of Chess, Articles 1.4.1 and 3.9.2, require a move to leave the moving side's king out of attack. Removing just one of these checks does not meet that condition.

At Durga Maa's offering area on Ishta Mel, offer the displayed group of red flowers, fruits, coconut, bhog and a deepak. When two attacks make the position feel overwhelming, seek Maa's protection and the courage to look at both before reaching for a piece.

Maa Durga, protect me from confusion when danger comes from more than one side. Bless me with courage to face what is there, and the wisdom to choose a path that is truly open.

The king has somewhere to go

Double check calls for a king move. In this position, e8–d8 is legal: neither the white rook nor bishop attacks d8, and the distant white king does not attack it. Moving e8–f7 is also legal.

Other neighbouring squares are unsuitable. The rook attacks e7. The bishop attacks d7. Black's own bishop occupies f8. Naming the safe square matters; “move the king” alone does not complete the answer.

This is therefore double check, not checkmate. Check describes an attack on the king. Mate requires that no legal reply remains. Here two king moves remain available.

Rebuild the starting position once. After Bb5, explain why the rook capture on b5 (Rxb5) fails without moving any other piece. Then explain why the bishop block on e7 (Be7) fails. Finally move the king to d8 and retrace both white attacks: neither ends on its new square.

When you next see two checking pieces, start by looking for the king's legal destinations. A capture that would work against one check can leave the other untouched.
