Morra Patterns and Quiescence Errors

I have to report another loss here. But I leave the battlefield with head held high. Because I did not give up after a knight loss. Fought myself back into the game and, alas, blundered it away in time trouble. Shit happens.

Two important notes here. First I missed a really basic opening pattern. Just because I have not come across it up to now. The Knight Fork of the Squares e8 and c4. The next pattern I have looked at, but not deeply enough. Quiescence Error, that is, stopping the calculation too soon, in a non-quiet position that is treated as if being quiet. I did this twice in the game. First missing a distinctive advantage. Second, after being back in the game, missing the last drawing chance in time trouble.

And now I come to the real point. I had looked at the line that would have secured an equal position. But I did not have the time to calculate it to the end. I just stopped at a point where I said to myself, sorry, boy, not sufficient. Then I switched to candidate move 2. Time was dripping away. Stress. No time now to look at candidate 2 as thoroughly as at number 1. And here comes the irrationality into play. I just hoped that number 2 must be better than 1. I was fully aware that it was not looking better at a glance. In fact, it was looking worse. All the same, I played it and, of course, lost.

I think I can learn a lot by looking at this crazy brain mechanism. It is what mankind always has done when in danger and despair. Just hope and pray that things will be ok. Stupid.

A proper way of handling the situation would have been as follows. Well, candidate 1 looks very promising. Calculate. O shit, it will not be enough. Now candidate 2. It overcomes a drawback of 1, but at what cost? O shit, not enough time to calculate. Quiet. No panic. Just have a look. Candidate 1 looks much better than 2. I have nothing to lose. Well, I play 1 and we shall see what happens now.

Okay, enough words. Here is the game.
