Schaakproblemen om virusproblemen te overwinnen!

Beste schakers,

Om in deze ‘eenzame’ periode toch nog regelmatig iets aan schaken te doen, plaatsen we de komende tijd wat puzzels, zodat je je niet meer hoeft te vervelen. Het is de bedoeling om elke 3 dagen een nieuw probleem op de site te zetten. Bij het probleem staat de opdracht. De oplossing zie je bij het volgende probleem. Deze problemen zijn wellicht wat pittiger dan die op de donderdagavond kunnen worden opgelost, maar hier kun je dan wat langer over nadenken. Je kunt er helaas geen pak koekjes of een fles wijn mee winnen; het is maar voor de aardigheid. De problemen die ik uitzoek, zijn vooral gebaseerd op schoonheid (volgens mijn smaak) en hoeven dus niet per se ingewikkeld te zijn. Tip om de problemen aan te pakken: probeer je in te leven in wat de componist wil laten zien (thema). Bij een remisestudie is bijvoorbeeld vrij vaak het idee om een patstelling op te zoeken. Bij een tweezetter kun je vaak ook kijken naar wat er zou gebeuren als zwart de eerste zet mag doen. Daar kan dan de oplossing liggen in ‘zugzwang’.
Hopelijk hebben jullie veel puzzelplezier de komende tijd.

Succes ermee!

Wouter.

Een puzzel van Sam Lloyd. Dit is het bekende ‘Steinitz Gambit’. Speciaal voor vandaag een mat in 3 waarbij de koning (het is vandaag Koningsdag, niet waar!) een hoofdrol speelt. Net als in het vorige probleem lijkt het de minst waarschijnlijke zet die tot winst leidt.
Wit speelt en geeft mat in 3.
