Eliminating Bad Candidate Moves (Filter Before You Calculate)

Most players don’t lose because they fail to calculate a brilliant line. They lose because they spend time calculating bad candidate moves — moves that were wrong from the start. This page gives you a fast, practical filtering system to remove bad candidates before you invest thinking time.

🔥 Calculation insight: If you calculate garbage, you play garbage. Waste less time analyzing bad moves by filtering them out instantly. Improve your candidate move selection to think like a master.

💡 Key idea: Calculation is expensive. First filter. Then calculate. A good candidate list is usually just 2–3 moves.

What Is a “Bad Candidate” Move?

A bad candidate is a move that looks reasonable at first glance, but fails a basic safety or logic test. It often collapses to a simple reply: a check, a capture, or a tactic you missed.

Bad candidates are usually:

unsafe (they lose material or allow a direct tactic)
slow (they ignore a threat that must be answered)
purpose-free (they don’t improve anything important)
hope-based (they rely on the opponent missing something)

The 30-Second Candidate Filter (Do This First)

Before you calculate variations, run each potential move through these filters. You can eliminate most bad candidates almost instantly.

1) Threat filter: does this move ignore an immediate threat?
2) Blunder filter: after I play it, do they have a check or winning capture?
3) Defender filter: does this move remove a critical defender?
4) Purpose filter: what problem does this move solve?
5) Time filter: is this move too slow for the position?

If a move fails any of these, it usually doesn’t deserve calculation time.

The Fastest “No” Test

If you want a single elimination question, use this:

After my move, what is my opponent’s best check or capture?

If the answer is “they win material / create a forcing threat,” your move is a bad candidate unless you can prove a concrete refutation.

Common Bad Candidate Types (High Frequency)

Watch for these classic traps in your own thinking:

“Looks active” moves that leave something loose
pawn grabs that open lines to your king or lose tempo
one-move threats that are easily ignored or refuted
automatic recaptures that fail tactically
natural developing moves that ignore a tactical problem

How Strong Players Eliminate Candidates

Strong practical players don’t “calculate everything.” They do this instead:

scan for opponent threats (safety first)
generate a small list of candidates (usually 2–3)
eliminate the unsafe/slow ones quickly
calculate only the survivors

This is why they look calm: their thinking is disciplined.

Eliminate Candidates by Position Type

When under attack: eliminate “slow” moves that don’t defend.
When you can win material: eliminate moves that miss forcing tactics.
In quiet positions: eliminate moves with no plan or no improvement.
In time trouble: eliminate everything except the simplest safe move.

A Practical Mini-Workflow (Copy This)

Use this as a repeatable routine:

1) Safety scan: what is my opponent threatening?
2) List candidates: 2–3 moves (forcing first).
3) Eliminate: remove any move that fails the “check/capture” test.
4) Calculate: only the survivors.
5) Final safety check: before you play the move.

Bottom Line

Better decision making is often just: eliminate bad moves faster. Filter your candidates first, then calculate the few moves that remain.
