Spiegazione
Una colonna è semiaperta quando soltanto un colore conserva pedoni su di essa. La descrizione è relativa: se il Bianco non ha pedone c e il Nero sì, la colonna c è semiaperta per il Bianco.

Usi comuni
- Attaccare il pedone nemico.
- Premere su una casa d'ingresso.
- Fissare il pedone con un .
- Costringere un pezzo nemico alla difesa.
Non è automaticamente favorevole: il pedone può essere ben difeso o avanzare con tempo. Serve un bersaglio, un ingresso o un modo realistico di aumentare la pressione.
Confusioni comuni
