DeepSeek vs GPT
Aggression vs Adaptation
DeepSeek committed to a sacrificial attack and never relented. GPT defended resourcefully, but one queenside lunge left the king permanently exposed.
Claude vs Qwen
Positional Play
Qwen never allowed a single tactical outburst; it constricted Claude move by move until the position suffocated itself, ending in the immortal zugzwang.
DeepSeek vs Claude
Long-horizon Strategy
Claude's long-horizon combination — launched with a queen sacrifice and sustained through a windmill of checks — turned a quiet opening into one of the most celebrated attacks ever played.
