>>493317865You have to learn simple chess before you can start playing complicated plans. I know you think you already do this but I can almost guarantee that at 1000 you don't.
Look at what your opponent is threatening and then defend it. If there is a way to defend it while developing a piece or putting pawns in the centre do it. If there are no concrete threats just develop. Do not start attacking before you've fully developed. GMs and engines sometimes pull this off but you are not a GM or an engine, you're 1000. Develop your pieces to squares where they're defended by pawns. This is extremely important. Even if you blunder you're at worst losing a pawn and not an entire piece.
Do not make random bishop attacks or knight jumps that look kinda scary but can easily be defended. Seriously, just don't do it. Don't threaten that juicy fork on f2 or f7 unless you have an actual concrete and theoretically sound justification. In fact, even if you do have that it's still better not to do it at your level, just play normally. Don't put your bishop on c4 or c5 if it can easily be kicked by your opponent playing d4 or d5.
Yes, it's a nice diagonal that pins the f pawn after castling but that's no reason to let your opponent put a pawn in the centre with tempo.
Play rapid instead of blitz or bullet. At the start of every move go through every single piece on the board(both yours and your opponents) and ask yourself "can this be captured". If you have the time you can look for more complicated tactics but even just doing a simple count(number of attackers vs number of defenders) is more than enough. This should take at most 20 seconds per move, way less as pieces get traded or as tension is resolved. This is a way better use of your time than coming up with some 7 move attacking sequence that gets refuted because a move you thought was forcing actually isn't.
Just not hanging pieces in 1 move and developing safely should get you to 1500.
