Biggest mistake is to force things when you already have big advantage.
You should play it easy. For example, instead 26. ... d4 you even could play 26. ... Qxf4. This should be situation where White struggles, not Black.
It's good that you put heart in attack, but somehow you have loose yourself to "only attack".
It depends what type of advantage you have. If you have an advantage in space than you should take your time. If you have an advantage in development is it not going to last, the other side will catch up, so you have to force the issue.
Thanks hamworld05, that's some great feedback.
I'm sending you a personal message transpo, that was an amazingly enlightening post having a length and depth I hardly expected in one of these comments.
