If you do away with the la Masa bull you'll improve much faster. Yes do tactics, even master them, but don't neglect endgames or position play. Playing games itself isn't going to help you improve. I know guys who are stuck for years at their current rating (even 1250 or 1600 USCF) and you could tell they don't even study, or at let did years ago and somehow stopped. The 1250 always flops horribly in an endgame while the 1600 has decent endgame technique and good tactics but gets careless. I know a few 1700s who are positionaally okay but flop at obvious intervals. Some of the unsound sacs they can typically get away with but if you keep your wits you can calculate creative solutions, and sometimes you defend against unsound sacrifices you see (ghosts?) Some 1800s are tough and won't let go of an advantage or equality...usually, but if they lose it have a hard time getting it back.
If you really don't know what to do then make an educated guess and calculate moves you think will make the opponent uncomfortable. Will you sacrifice a knight, bishop, or even a rook to make their goals of completing development very hard practically, making your position easier to play despite the material deficit? Then go for it.
Otherwise just look at the imbalances, calculate potential tactics, if none are there then form a plan, come up with candidate moves, and pick the one that leaves you best off.
I managed to go up 174 points last year purely self training and playing games against other people, it's how I became an NM. I'm sure you've heard it's harder to increase rating points the higher up you go in chess. So if you have a good coach, and train as hard and consistently as I did the entire year (2-3 hours a day on average), with the right study materials, you'll probably be able to go up somewhere between 300-600 points from your current level. It's possible but very difficult, good luck.
yeah but probably you are gifted and i think i'm not, i'm doing tactics and playing games that's all, i don't know what to do, i started learn chess openings but i thought it was less important than chess vision.
can you tell me your IQ?
