Yeah, those are probably the hardest to play. For me too at least. Especially when all the pieces look good, but there's seemingly nothing to do with them. Not sure I can help much.
There are all types of equal positions though. Some are a lot more dynamic than that, and maybe there are plans but you're having trouble weighing the pros vs the cons? I don't know. An example position would help.
I'm good with increasing an advantage and finishing a game off.
At a disadvantage the moves aren't usually hard to find. Play your forced moves and keep an eye out for opportunities.
But I think I'm at my worst in equal positions. I drift, get impatient and make a mistake, don't find a plan, and generally just have a really hard time.
Advice would be appreciated.
