Þeir félagar Vignir Vatnar Stefánsson (2484) og Aleksandr Domalchuk-Jonasson (2407)hafa báðir 3,5 vinning af 5 mögulegum og eru taplausir á Heimsmeistaramóti U20 í Mexíkó. Frídagur er í dag.

Vignir hafði svart gegn Portúgala, Jose Guilherme Santos Barria (2392) en hann er FIDE meistari. Vignir jafnaði taflið auðveldlega með svörtu en það var ekki nægjanlegt líf í stöðunni til að tefla til vinnings og hvítur virtist sáttur við jafnteflið.

Aleksandr Domalchuk-Jonasson (2407) fékk hvítt á Frakkann Joseph Girel (2494) en sá er alþjóðlegur meistari. Skák þeirra varð öllu líflegri. Svartur náði frumkvæðinu í miðtaflinu/endataflinu með betri peðastöðu og betri biskup og Aleksandr var í hálfgerðri nauðvörn lengst af.

Frakkinn var kominn langleiðina með að brjótast í gegnum varnir Sasha þegar honum verða á mistök í 63. leik

Hér lék Frakkinn 63…Hg2? og hér hefði Sasha getað snúið vörn í sókn með 64.Hxd5! og hvítur stendur til vinnings útaf frípeðunum sem myndast. Sasha lék þess í stað 64.a5 en var samt kominn inn í taflið. Svarti kóngurinn stendur illa í báðum varíöntum.

Sasha var líklega kominn með aðeins vænlegra endtafl og hér er 69.c5 örugglega betra á hvítt. Okkar maður var hinsvegar í basli á klukkunni og eftir langa vörn 69.Bd2 Hh3 og 70.Ha6+ skiljanlega meira freistandi framhald í stöðunni. Hvítur þráskákar á a- og b-línunni og jafntefli niðurstaðan.

3,5 vinningur hjá þeim báðum eftir umferðirnar 5 eins og áður sagði. Enn liggur pörun ekki fyrir en samkvæmt rannsóknarvinnu Skak.is ætti Aleksandr að fá svart á stórmeistarann Momchil Petkov (2499) frá Búlgaríu en Vignir svart á Savva Vetokhin (2400) sem er Rússi en teflir undir fána FIDE.

Um mótið:

Ísland á tvo fulltrúa á Heimsmeistaramóti 20 ára og yngri í Mexíkó. Stórmeistarinn Vignir Vatnar Stefánsson (2484) er númer 19 í styrkleikaröðinni og Aleksandr Domalchuk-Jonasson (2407) er númer 36 í styrkleikaröð. Stigahæstur keppenda er hinn umdeildi Hans Moke Niemann (2667) sem hefur verið mikið milli tannanna á fólki undanfarið. Skráðir keppendur eru 149.

Tefldar verða 11 umferðir og er dagskráin eftirfarandi (tímar íslenskir)
