i'm on some kind of a streak now.
on november 12, i was 1546 blitz and since then, i've been mostly winning. after my last win just a few minutes ago, i'm at 1704.
i largely suspect this is artificial improvement - i've not been doing any tactics or studying. i've just been playing lots of blitz (casual and rated), with a smattering of classical games here and there.
it's so much fun to simply play.
