I've gotten a handful of GMs now, the most recent of which clocked in at 12:31:45 & felt like a pretty even game for me. I have some amount of room to improve on locking time (I could probably just barely get to sub-12 without changing my stacking on a similar run that just went frenetic), but mostly I need to improve my stacking. At a certain level, I've just gotten good enough at recovering my mistakes & fast enough at inputting to compensate for my stacking technique. Now there are actual misdrops here & there, but for the most part I put myself in sticky situations that cause minor-to-moderate mistakes. The most common of these is creating a castle-like stack, with a bunch of 1-deep holes across most or all of my stack. Does anyone have any good tricks for getting out of these situations or any advice on what to avoid when planning piece placements? I'm pretty mindful of trying to leave at least 2-wide gaps whenever I have some choice in the matter. (And of course it's possible I'll just have to learn to feel this one out better.) In terms of recovery from the castle effect, I'd say I'm overly hesitant about stacking over a single hole in the middle, and now that I'm actually thinking it out, I guess I'm answering my own question. Any good examples or tips about that though? Do you usually try to cover up the middle of the stack, or do you start from the sides if it's the first half of the game?
