NK jeugd met Tobias
Tobias deed vorige week mee aan het Nederlands kampioenschap voor A-jeugd (tot en met 18 jaar) in Almelo. Hij had zich een paar maanden geleden geplaatst voor de finale via de online voorrondes. Het was van te voren al duidelijk dat het voor Tobias een zwaar toernooi zou worden. Tobias heeft een rating van 1443. Dat is wel een beetje laag ingeschat, maar toch: aan het toernooi deden negen schakers mee met een rating boven de 2000, met een uitschieter van 2292.
En het werd ook geen gemakkelijk toernooi. Uiteindelijk moest Tobias met een score van 1,5 uit 7 genoegen nemen met een plaats in de achterhoede. Toch: alleen al het feit dat je je plaatst voor het Nederlands kampioenschap na zware selectietoernooien is al een prestatie om trots op te zijn. En volgend jaar nieuwe ronde nieuwe kansen: met de opgedane ervaring kan het alleen maar beter worden.
Tobias was zo vriendelijk om drie van zijn partijen van commentaar te voorzien voor de website. In de eerste partij laat Tobias met zwart zien hoe je gebruikmaakt van het loperpaar in een open stelling. De tweede partij is een moeilijke positionele strijd, waarin Tobias lange tijd goed meekomt. Uiteindelijk laat zijn tegenstander zien waarom hij een veel hogere rating heeft. En de derde partij is vooral grappig omdat er vanuit een verloren stelling toch remisekansen ontstaan. In een eindspel met toren tegen twee paarden en een pion is het enige wat je hoeft te doen de pion slaan: met twee paarden is mat zetten niet meer mogelijk. Helaas kon Tobias de juiste weg naar remise in tijdnood niet vinden.
