To calculate effectively, we need a structured mental model. This process moves from general assessment to concrete calculation, ensuring we don't miss hidden resources or fall into traps.
Positional Assessment (Static)
Before looking for tactics, assess the static features of the position. This determines your priorities.
- Is the position open or closed?
- Does your playing style favor a slow squeeze or a sharp attack?
Tactical Assessment (Dynamic)
Identify the specific Combinational Motifs (as defined by Romanovsky) that exist in the position. Their presence increases the probability of a winning combination.
- Targets: King safety, loose pieces, back-rank weakness.
- Patterns: Pins, forks, skewers, overloaded pieces.
Concrete Calculation
Once you have identified targets, begin brainstorming candidate moves—even the "crazy" ones!
Prioritize moves that are:
- Forcing in nature: Checks, captures, and threats limit the opponent's responses.
- Linked to strategic goals: Moves that implement your overall plan (e.g., creating a passed pawn).
Soundness Check
If your analysis produces a combination (especially one involving a sacrifice), you must check it for soundness.
Look for "Avoidance Moves":
In the puzzle discussed in previous lessons (where Black played Qf6), it is crucial to realize that White is not forced to accept the mate immediately. White can "avoid" the main line by playing Qg3, giving up the rook on b2 to survive.
Always ask: "Can my opponent ignore my threat and play something else?"
