What is a discovered attack in chess?

A discovered attack happens when you move one piece and reveal an attack by another piece behind it. In this puzzle, a bishop moves with check and uncovers your queen's line to the black queen, turning a pin into a winning refutation. The enemy is too busy meeting the check to save the attacked piece.

How do you respond when your bishop is pinned to your queen?

Never assume a pin means retreat. Look for checks and counterplay first, since a pinned piece can often still give check or capture along the pinning line. Here the pinned bishop strikes with a sacrifice, forcing a recapture and winning the undefended queen. If your counter-blow wins more than the pinned piece is worth, the pin works against the opponent.

What is a tactical refutation in the middlegame?

A tactical refutation is a stronger reply than your opponent's threat demands — often a check that wins material while answering the attack. In middlegame positions, an undefended queen and a loose king are the two warning signs to look for. If your opponent attacks one of your pieces, look for your own blow against their king before defending.

Why is an undefended queen a serious weakness in the middlegame?

An undefended, hanging queen is a magnet for tactics because any check that distracts its defenders may leave it capturable. In this position black's queen has no protection, so once White forces a recapture with check, it falls to the queen on the open file. Always count how many pieces defend your queen before you commit it.

What should you look for when your opponent plays a cheap attack?

When an opponent's move feels aggressive but leaves pieces loose, check whether it creates a genuine threat or just a cheapo. Look for undefended pieces, open files between the queens, and checks that break pins. A cheap attack usually leaves a flaw behind — finding that flaw and striking with check is how you win a queen in the middlegame.

Can a pinned piece still give check?

Yes. A piece pinned to the king cannot legally move off the pinning line, but it can still capture or give check along that line. That is exactly what makes a pin-breaker sacrifice possible: the pinned bishop gives check, forcing a reply, and the distraction costs the opponent their queen. Practise looking for checks from pinned pieces in your own games.

French Defense Tarrasch Variation Puzzle (Rated 1056): Win a Queen — The Pin

When your opponent pins your bishop to your queen, retreat seems like the only reply. This middlegame position teaches the opposite: the pinned piece can strike back. A checking sacrifice on the king's doorstep forces a tempo-consuming recapture, and the line your bishop left behind stays open. The undefended enemy queen falls, and what began as an attack against you becomes decisive material gain. One accurate counter-blow outvalues any slow, safe move — pins are only as strong as the threats that support them.
