OK, after several sessions wielding my mouse against the solutions offered by the tactics trainer, I've learned that my "gut" is good for an assessed rating of between 2150 - 2250, with a peak rating in the low 2300s.
Of course, I have no idea what that means relative to other players, since those ratings don't seem to be posted anywhere. SO, in a nod to Maslow's hierarchy in which I claim to operate primarily under the raison d'etre of self-fulfillment (or some such psycho babble), I've decided that my gut needs some surgery (sorry for the mangled metaphors, but then again, who cares).
So, I'm going to start trying an approach other than narrowing my choice down to 2 or 3 moves and then flipping a mental coin (if the choice is 3 different moves, then I allow the mental coin to land on edge...and stick the landing...if I have more than four choices I use a die--or dice). What's my approach to "improving"? Start figuring out on which puzzles I'm most likely to guess wrong...hmm, wonder if I can look at the puzzles I've already tried...anyway, I'll look at the tags and see if there is a common tactical theme(s) that I screw up.
Sure would be nice if all the puzzles were tagged!
