MATING AGAINST 0-0
Together with Fritz you can practice mating attacks against the castled enemy king. In the first part you get to know the typical mating motifs and combinations by means of training tasks. In the second part you can then apply your freshly acquired knowledge by winning test positions against Fritz. But careful - against such a tough defender any inaccuracy will be mercilessly.
