I'm not necessarily thinking about changing my "style" or whatever. I kind of did 3.5 years ago on the advice of my first chess coach (YKW). Although he didn't really say I had to do anything but mentioned my games from 10+ years ago had me playing very static, dry, and safe positions. That for me to get better and possibly enjoy chess more I could try playing more dynamic positions and even, *gasp*, intentionally go into unclear positions.
My repertoire is a bit odd as it can lead to many dry and boring positions but then also very dynamic ones - which I think works very well.
One thing my current coach mentioned later today was that part of it could be that I don't give my opponents a chance to blunder. I assume what is essentially meant is rather than finding ways to keep pressure (or perhaps the "squeeze") and build up tension, I tend to be on the lookout to either force concrete lines or make moves to find concrete lines. I do think there is some of this going on. Especially when I have an advantage I do not think I'm very good or comfortable yet with simply letting the advantage "sit" for many, many, moves - which is a much safer way for me to potentially play if I can do it well and I imagine lead to these elusive blunders from my opponents.
Or just go into very crazy positions. But while I have won some nice attacking games, I don't tend to go for material sacrifice unless I can clearly see a way to get it back or am very sure it will be winning. For instance, in the game last night I spent a ton of time trying to figure out if a particular sacrifice would work - but my opponent didn't have to even allow it, he had other responses to the move I was thinking about playing. All that wasted energy could have just been used to win a pawn, make a few normal moves, and then having more time later in case things got complex (which they always do again).
But, okay, I agree that this kind of focus/thinking is a bit silly. The Gelfand books I have may help in this regard - or at least his first book. I may want to read it a few times as it's kind of an ode to Rubenstein and squeezing one's opponent - there are some very, very complex lines in some of the games, it's not that they aren't dynamic, but Gelfand finds ways to parry counterplay and just slowly squeeze his opponent, never seeming to worry too much about exactly how he will win or if he will win until his position becomes clearly winning to himself.
