VVS_Mexiko — Vignir að tafli á HM U20 árið 2023 Mynd. David Llada

Vignir Vatnar Stefánsson (2484) vann sína skák í sjöttu umferðinni en Aleksandr Domalchuk-Jonasson (2407) laut í dúk í fyrsta skipti á mótinu.

Vignir mætti alþjóðlega meistaranum Savva Vetokhin (2400) sem er Rússi en teflir undir fána FIDE. Vignir hafði svart og upp kom drottingarbragð. Vignir náði að jafna taflið og segja má að eitthvað „juð“ hafi verið í gangi þegar Rússinn einfaldaði taflið kjánalega strax eftir að tímamörkunum var náð. Vignir var þá kominn með aðeins betra tafl.

41.Df5? var slakur þar sem svartur drepur og kóngurinn kemur strax og nær peðinu. Vignir fékk vænlegt hróksendatafl sem hann kláraði vel.

Á sama tíma tapaði Aleksandr gegn búlgarska stórmeistaraum Momchil Petkov (2499) með svörtu. Aleksandr tefldi hraustlega í mótteknu drottningarbragði. Svartur fór í aðgerðir á kóngsvæng en endaði á að fá það í bakið og hvítur hafði betur í miðtaflinu.
