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

Vignir Vatnar Stefánsson (2484) og Aleksandr Domalchuk-Jonasson (2407) gerðu báðir jafntefli í sjöundu umferðinni á Heimsmeistaramóti 20 ára og yngri í Mexíkó.

Vignir hafði hvítt gegn Norðmanninum efnilega Elham Amar (2541). Norðmaðurinn var stigahæstur á EM ungmenna á dögunum en hafði ekki sigur þar þrátt fyrir að vera í toppbaráttunni.

Vignir fékk ágætis stöðu úr byrjuninni en náði ekki að fylgja því eftir og miðtaflið varð að algjörlega jöfnu tafli í lokaðri stöðu. Vignir fór líklega í röng uppskipti á hvítreitabiskupum og staða Norðmannsins fór að verða betra með pressu á e-línunni og veikur e4 reitur hjá hvítum.

Vörnin hjá Vigni varð erfiðari og erfiðari og á einhverjum tímapunkti stóð Normaðurinn líklega til vinnings. Vignir varðist þó af krafti, gaf peð og fann virki (e.fortress)

Hér leikur hvítur 54.Hc6 og fær nægjanlegt mótspil. Svartur á enga reiti til að komast í gegn með kónginn ef hvítur heldur hróknum á c-línunni. Varnir hvíts héldu, sem betur fer!

Vignir heldur sér því í seilingarfjarlægð við toppinn. Hann fær svart á indverska alþjóðlega meistarannn Harshavardhan (2397) í áttundu umferð.

Aleksandr fékk hvítt á aljþóðlega meistarann Cameron McGowan (2161) frá Ástralíu. Upp kom kóngsindverji og var Gligoric afbrigðið teflt. Svartur virtist hafa sitt vel á hreinu og Aleksandr fékk í raun lítil tækifæri til að tefla til vinnings. Endataflið sem kom upp var frekar þurrt og lítið hægt að reyna.
