Would really help to let people know what ELO/USCF rating you're currently at. People plateau-ed at different rating classes tend to have many roadblocks, but there are some telling common denominators based on where you're stuck.
If you don't have any federation rating games under your belt (you only play online or only have a computer program guesstimate your rating for you), it gets a lot more unclear. If this is the case, perhaps posting a sample game of your most recent loss would help.
I was planning to read a book on planning in chess, followed by a book explaining all the moves in chess. I might read My System or maybe Thinking like a Grandmaster after that, but I'm not sure. Then, I'll improve on my tactics by doing 100 puzzles everyday along with any other books. Does anyone have a better plan or any books they might suggest? I sort an intermediate player still so...
