Question to consider, Sport. Are you getting frustrated at some short-term results? Seems to me you were cruising right along, then seemed to hit a brick wall. But keep in mind that that's part of the natural course of poker. You need to keep one eye at all times at your overall, long-term results. And the long term is ... well, long.
As I've mentioned here a couple of times, I've been on a nasty streak just like yours, where almost nothing I do has a good result. And I was finished, done with SnGs. I was convinced I had completely forgotten how to play them.
But guess what ... after a couple of weeks of only playing sporadically and not thinking about it much, I played one a couple of days ago and nailed a third place. Then I played another one and nailed another third. Then I waited another couple of days, played another one and won it. Won a second one.
And all of a sudden, I'm feeling good about my SnG play now. And I really don't think I'm doing anything different ... except not making a tilted, forced play at a critical point out of frustration.
I dunno, just a suggestion. But does that sound familiar to your situation, by chance?
