The Modernized Catalan - Volume 1

'Writing an opening book is always a challenging endeavor—especially in 2025. How long will the suggested lines remain relevant? Computers may soon refute certain analyses. Tournament practice might uncover more effective continuations. And some lines may simply fall out of fashion. This has been the fate of virtually every chess opening book ever written. 'Yet despite these uncertainties, opening books remain both useful and necessary. Why? Because the author plays a crucial role: selecting lines from a vast sea of millions of games, deeply analyzing them, highlighting key moves and variations, explaining underlying ideas, and finally, offering objective evaluations. 'In this work by Hungarian International Master Balázs Csonka, all of these tasks—so far as I could assess—have been executed at an impressively high level. 'This excellent and sophisticated work not only helps us grasp the fundamental ideas, plans, and tactical motifs of the Catalan but also dives into fresh, cutting-edge computer analysis. It is a valuable contribution to both modern opening theory and the legacy of the Hungarian chess school.' —József Horváth, Grandmaster and FIDE Senior Trainer, Budapest, April 2025
