My Advice for "Beating" the Tactics Trainer
For tactics, most of them are either mating attacks or some kind of double attacks. So I'd quickly look to see how the other King is protected, and then check (no pun intended) out all your checks; no matter how ridiculous they look. If the checks don't seem to work out then it's time to look at undefended pieces or pieces that are attacked the same amount of times as defended; I call this critical squares.
