Aleks Peshkov, a Russian software developer and computer chess programmer. Aleks contributed to various methods of generating sliding piece attacks in bitboards, most notably he pioneered in the Hyperbola Quintessence approach regarding the union of positive and negative ray-attacks, further utilizing disjoint ray-attacks in conjunction with own inverse and mirroring or flipping distributive xor instruction, also suggesting SSSE3 Hyperbola Quintessence using the Pshufb instruction for the vertical flip. Aleks also supported the Stockfish development in making test resources available.
