Candidate Moves & Calculating Variations

Tactical mastery is the art of destroying your opponent's position using forcing sequences like forks, pins, and skewers. However, spotting a tactic is only the first step; calculating it accurately ensures the sacrifice works. This hub connects you to essential lessons on candidate moves and calculation techniques, transforming "hope chess" into precise, disciplined execution.

๐Ÿงฎ Calculation insight: Spotting a tactic is one thing; calculating it to the end is another. Don't rely on "hope chess." Learn the disciplined process of calculation to verify your attacks work.

Initial Candidate Moves

Brainstorming is a vital technique when analyzing the initial candidate moves in a position. This involves not rejecting moves simply because they appear "bad" or "crazy" at first glance. Instead, you must look at all possible moves coldly and detachedly.

By this process, you risk finding truly creative moves that you would not normally consider!

Can you see the implications?

Prioritising Candidate Moves

As human beings, we cannot see millions of moves per second. We must prioritize. Moves which should be given priority in analysis include:

  1. Forcing Moves: Checks, captures, and threats. These limit the opponent's responses, making calculation easier.
  2. Strategic Moves: Moves clearly linked to your plans (e.g., creating a passed pawn, removing a defender). These are "logical" tactics that support your overall goals.

In standard Over-the-Board (OTB) play, brute force calculation is impossible due to time constraints. You must filter candidate moves based on practical positional understanding and your strategic game plan.

Spotting Good Candidates

What should we invest our time in? The identification of tactical motifs (pins, king safety) provides the raison d'รชtre for potentially good combinative moves.

However, we must also leave creative room to appreciate the significance of the seemingly insignificant.

If you want to be a good combinative player, you must be prepared to break the "rules." Think about giving up a Queen for a pawn! You might find it forces a mate in 5. Without this creative freedom, your calculation will always be restricted by habit.

One must develop an instinctive feel for subtle resources. A quiet pawn move might look insignificant but could open a crucial file that turns the game in your favor.

Beautiful Combinations

In calculating variations, beautiful hidden resources may be revealed. However, one should not go all out to find a combination in every position.

Warning: Only look for a combination if the position justifies it. If you try to force a combination in every game, you will find unexpected brilliance 5% of the time, but lose on time (or blunder) in 90% of games.

Why Computers Are Better Tactically

Humans filter moves based on experience and intuition. In 1 case out of 100, a seemingly random, "bad" move that we filter out might actually be the winning move.

This is where humans lose to computers.

Computers do not have prejudice. They use a brute force approach to analyze moves that a human would never consider. Our experience guides us quickly to good moves, but it also creates a "blind spot" that prevents us from seeing the exceptions to the rules.

We must accept that we are tactically weaker than machines, but we can learn from their detached, systematic approach.
