Ach Jekatierina, czemu tego nie zobaczyłaś?

W pierwszej rundzie Mistrzostw Turcji w szachach Jekatierina Atalik zagrała czarnymi z Vahap Sanal. Mimo, że przewaga rankingowa była po stronie białych (2557 do 2450) padł remis.

Jednak w pozycji na diagramie Jekaterina mogła zagrać piękną kombinację:

Teraz czarne zamiast Gf7 mogły zagrać 18...S:c2 i po 19.S:c2 czarne grają Gg4 i ginie biała dama. Ach Jekatierina, czemu tego nie zobaczyłaś?

Potem jeszcze Atalik miała wygraną partię, ale nie wykorzystała swoich szans i partia zakończyła się remisem. Przebieg partii:
