Check First in Chess: give check before the logical move

Checking first is one of those tactics that, once you understand it, you start seeing everywhere. And the best part: your opponent doesn’t expect it. The idea is simple but powerful: before making the “logical” or “natural” move, you give check. And that check changes everything.

The concept: a tempo that changes everything

What exactly is it? Let’s see. Imagine you’re in the middle of a piece exchange. Your opponent just captured something and you “should” recapture. That’s what anyone would do. But instead of recapturing, you give check with another piece. Your opponent has to respond to the check no matter what — move the king, block, or capture the checking piece. And while they respond, you take the chance to improve your position, save a threatened piece, or create a second threat.

That extra time you gain is a tempo. And a tempo at the right moment can turn a lost position into a winning one.

The zwischenschach: the in-between check

In German it’s called Zwischenschach — literally, “in-between check.” It’s the purest case of checking first and a specific variant of the in-between move. The typical sequence is this:

1. Your opponent captures one of your pieces.
2. Instead of recapturing immediately, you give check.
3. Your opponent is forced to deal with the check.
4. After they resolve the check, you recapture… but now with a better-placed piece, or having won extra material along the way.

Why does it work? Because your opponent calculated the sequence assuming you were going to recapture. They didn’t account for the in-between check. Their calculation breaks and the outcome of the exchange shifts in your favor.

When to look for checking first

There are three classic situations where checking first appears frequently:

1. In the middle of piece exchanges

Every time you capture or get captured, pause for a second before automatically recapturing. Look at the board and ask yourself: can any of my pieces give check? If that check lets you move a piece to a better square before completing the exchange, do it.

2. When your opponent’s king is exposed

A king that hasn’t castled or has few defenders is a perfect target for checking first. With the king exposed, the chances of giving check with queen, rook, bishop, or knight multiply. The more exposed the king, the more likely a devastating first check exists.

3. To save a threatened piece

Your opponent threatens to capture your queen. Instead of retreating it, you give check with another piece. While your opponent deals with the check, you move the queen to a safe square. Result: you saved the queen and gained a tempo with the check. Your opponent lost a turn responding to the check instead of executing their threat.

The autopilot trap

Do you know what the biggest enemy of checking first is? Autopilot. That mental mode where you recapture without thinking because “it’s the logical thing.” Strong players never recapture automatically. They always ask themselves: is there something better than recapturing?

And the answer, more often than you’d think, is yes. A first check, a checkmate threat, an in-between fork. Autopilot makes you miss these opportunities.

How to train yourself to see checks first

The key is building a habit. Every time your opponent captures a piece and you’re about to recapture, stop. Spend five seconds scanning the board for possible checks. Just five seconds. If there’s nothing, recapture. If there’s an interesting check, calculate the full sequence.

Over time, that scan becomes automatic. And once you master it, you’ll discover that many games are won (or saved) with a simple check at the right moment.

Checking first isn’t a spectacular tactic. It doesn’t show up in brilliancy books. But it’s one of the most practical tools you can have in your tactical arsenal. Use it.
