Goldsmith Defense Picklepuss Defense Double Check in Chess

The Goldsmith Defense Picklepuss Defense Double Check is a tactical motif where the defender’s sequence creates a double check on the enemy king—typically by combining a direct checking piece with a second discovered or secondary line check. In the defining feature, the defender leverages the Picklepuss setup to open a line while simultaneously delivering check, forcing the king to respond immediately. For an intermediate player, the key idea is that the double check removes the usual “choice” of defenses and makes the tactic highly forcing.
