Puzzle 1 / 12
The Shattered Bastion
White to move, mate in two.
I was honestly surprised by how strong this engine is. The adjustable levels make it fun for training, and the higher levels punished every mistake I made. Excellent value for the price.
The puzzle solving is incredibly fast and accurate. I uploaded several difficult positions from tournament games and received excellent moves every time. Highly recommended.
I bought the $4.95 package just for practice and ended up playing all ten games in one evening. The adjustable strength is perfect for improving without getting completely crushed.
The Level 7 package is absolutely insane. You can actually feel the engine getting stronger after each game. If you need serious preparation against someone, this is worth every dollar.
Clean interface, instant access and very strong analysis. I especially liked that I could submit my own positions instead of only playing games.
I have tried several online chess engines and this one is among the strongest I have ever used. The calculations go incredibly deep and tactical positions are solved almost instantly.
It took me a few games to understand how the different strength levels work, but once I did I really enjoyed it. Great training tool and the analysis helped me find weaknesses in my openings.
The Ultimate package feels like having a professional analyst available whenever you need one. The preparation against specific opponents is particularly impressive.
Very professional service. The engine plays creative, aggressive chess and found tactical ideas I completely missed. I will definitely come back for more games.
Excellent experience from start to finish. The email login worked flawlessly, the games started immediately, and the engine strength exceeded my expectations. One of the best chess services I have used.
