Recently I faced a problem I've been facing a huge issue with my play in chess - My weak psychology. What happens is lets suppose out of 30 moves I play 29 good moves (not always objectively good but good considering my current rating level and time, these including inaccuracies, mistake and blunders impossible for my rating level to everything spot or at least avoid), but for rest of the move, my weak psychology makes me make a critical blunder losing the game immediately. And you might consider my thought process, calculation method or thinking system, saying for blunder checks, etc but my overall though process avoids many blunders, also checks for opponent's best responses I can find. The overall reason I can understand is it being combination or nerves and crumbling, under time pressure.
In all the games I play, I mostly choose 30 mins because I wanted even more like 60 mins for 60mins you wait for minutes but still no pairing so I play 30 min. Initial moves are fine and good too, many of the games I had completely winning positions but then the clock falls and both players below 12 or 10 mins, I have two choices: keep playing accurate or play fast. You have definitely consider that in all of the games I always remain slightly behind in time, enough though time gap is not Both have led to me losing. My initial approach of playing accurate was followed still 1200 but opponents began to flag me. Then I started the approach of playing fast. But there is a huge problem, when playing fast I have to rely on my intuition, thus I don't even have to time to calculate everything. But this is not the end, in fact what I said was just slight beginning. The main thing begins before even the less time comes, the nervousness having to play 20-30 more moves or even more in low time. Slowly even I try to focus and avoid the nerves but still the past experiences of both trying to play accurate and getting flagged to past blunders due to playing fast both begins to haunt me. I can't just control everything, also I cannot try to calm myself down on the board because I always slight remain behind in time and not much time left so I have to make moves too. These all dramatic emotional roller coaster just creates such mental blur that I can neither rely on intuition nor think consciously properly due to this.
This game clearly demonstrates this.
