Hey everyone. Hopefully the title is clear enough.

I am looking for a tactics trainer, like chesstempo.com , where I can play with a 3D board, to help with over-the-board visualization. Is there such a free server? Or atleast a paid one? Thanks.

Tactics Trainer has a 3D board. It is free for up to 5 problems a day, if you can visualize that.

That looks OK, but it's very small. Is there a way to enlarge it?
