Blunder completely transformed my chess game. I was stuck at 1200 ELO for years, and within 3 months of using the platform, I broke 1350. The personalized feedback on my games is what made all the difference.

As someone who's been playing chess casually for years, I was amazed at how quickly Blunder identified my weaknesses. The opening explorer and endgame training have been game changers for me.

The tactical pattern recognition feature helped me spot combinations I would have missed before. I've gained over 200 ELO points in just 4 months. Worth every penny of the premium subscription.
