Fear of Death in Chess.
Dan Heisman teaches in his writings that there is a feedback loop when it comes to learning chess, that without it, little to no growth will occur. I'm not going to get into the nitty-gritty details of the feedback loop, just that one must add positives and subtract negatives in order to improve in chess. Positives are stuff that you are doing right, and negatives, are stuff that you are doing wrong.
Occasionally, when I play chess, I run into the problem of quitting the game simply because my opponent does a bold move that at first glance seems like an unstoppable attack. However, I am learning, that often times in the opening game and even in most instances when you have a healthy number of pieces to defend vs a healthy number of attackers ratio that either equals both sides or favors the defender, then usually, there is a way out of the bold looking often desporato type tactic that for me often causes all the time to just suddenly disappear from my clock.
Granted I generally take longer than usual to come up with chess moves in blitz, however, in situations where my opponent does a bold move that at first glance creates an unstoppable attack, in at least 3 memorable cases, where I gave up but could have continued to probably win the game, I had a way out of what in my head was thought to be an unstoppable chain of events that would spell my doom.
I later see now that he could have pushed the pawn earlier before moving the queen to take my knight that had no squares to go. So I would have been down a minor piece. You see, now that I see this, I conclude that this sac is actually good against the dragon, and will have to adjust my moves when playing this way from now on.
