If you are very good at tactics but can't seem to spot and exploit them in your games, then it's probable that one of two factors is holding you back.
Either:
1) Poor situational awareness. Perhaps the tactical opportunities do come up in your games, but you miss them because you fail to spot them and just play some boring move "on auto-pilot" instead. This can happen because there is one major difference between tactics puzzles and a real game: with the puzzle, you already KNOW from the start that a winning tactic exists; you just need to find it. In a real game position, you have no such assurance.
2) Poor strategy, poor positional play. Tactical opportunities don't just float down out of the sky like snowflakes. They appear in positions where you already hold the advantage. This is just common sense... you won't find a winning move unless you have a winning position. That's what MAKES it a winning position: tactics flow from a superior position. So perhaps it's your strategy that's at fault... you don't see any tactical opportunities because you never reach the positional superiority that would generate tactical solutions.
i usually dont study openings and lines and i am a positional player... Whenever i try a not so obvious tactic, my opponent always spots it
I would laugh at them and stalk their games for hours and compile a list of games where they get completely molested by their opponent, heavily annotate it with snark remarks and post it in a public forum
Hahahahaha. I hate to think what you'd do to someone who actually wronged you...
Mental note: don't piss off B1ZMARK. He wouldn't have to search through many of my games lol...
Well id probably do nothing
