Is one particular puzzle giving you difficulty? We’ll show it to you again a little later so you can prove that you’ve learned from your mistakes! Blindfold Tactics. Are normal Tactics Puzzles too easy? Test your skills with our Blindfold Tactics, where you have to visualise and solve the position simultaneously! Blunder Preventer. Given two possible moves, do you think you can spot the blunder? It’s not always as easy as you’d think! 360 Trainer.

With no clear material gains available even the smallest positional advantage could be the right move! Practice Visualisation. Memorize a board and then answer questions about where the pieces were, how many undefended pieces there were, or even what moves you need to make to capture certain pieces. Checkmate Flash Cards.
