Una obertura semioberta o partida semioberta, és una obertura d'escacs en què les blanques juguen 1.e4 i les negres trenquen immediatament la simetria tot contestant amb un moviment diferent de 1...e5.


Aquest article empra la notació algebraica per descriure moviments d'escacs.

Defenses populars[modifica | modifica el codi]

La defensa més popular de les negres contra 1.e4 és la siciliana, tot i que la francesa i la Caro-Kann també es juguen molt. La Pirc i la moderna es veuen també sovint, mentre que la Alekine i l'escandinava han aparegut ocasionalment en el Campionat del món. La Nimzowitsch és jugable però rara, igualment com la defensa Owen. La Borg i la St. George són rareses, tot i que Tony Miles usà una vegada la defensa St. George per guanyar el llavors campió del món regnant Anatoli Kàrpov.

La siciliana i la francesa condueixen a posicions desequilibrades que ofereixen un joc interessant amb els dos bàndols tenint possibilitats de guanyar. La defensa Caro-Kann és més sòlida, ja que les negres empren el seu peó-c per recolzar el seu centre (1.e4 c6 2.d4 d5). L'Alekhine, la Pirc i la moderna són obertures hipermodernes, on les negres tempten les blanques a bastir un gran centre, amb l'objectiu d'atacar-lo amb peces.
