Interesting game.  The components are nice and the game play exciting for an abstract.  I’m a big chess fan, so I have a high tilt towards this type of board game.  I’ve played several games of Blokus and have not been able to discern any beat all moves.  The diagonal strategy towards the middle of the board is reminiscent of chess, and the corner remind one of Othello.  And, yes, of course it looks like Tetris.

 Update:  I just found Blokus Online Play.  I lost, but it was fun.  Found the original post for this here.
