Caissa poster's note: I suppose that there's a chess analogy here; Ie. The {article} mentioned 'avoid predictability' as the combat 'moral.' Which 'imho' as far as chess is concerned; Mainly involves those Not often seen circumstances, where one is playing a prolonged, multi-game 'match,' with a known opponent.
.. Anotherwords; If one considers themself, objectively 'good' at playing chess online or elsewhere, in a 'certain manner' {as it were}; By all means; Continue to, "Dance, with what brung you," to that point of past successes! --

The Men I Lost /By Bernard E. Trainor
 
 
By 1952 both sides had been dug in for months along the 38th Parallel. As peace talks began in Panmunjom, a village along what became the border between North and South Korea, they jockeyed for the smallest terrain advantage in anticipation of a cease-fire. The result was an endless series of seesaw battles for outposts in front of mainline positions, similar to the trench warfare of World War I.
 
I was a Marine infantry platoon leader on the front line, not far from Panmunjom. One warm spring night a patrol from my unit was heading out when the Chinese ambushed them right in front of our platoon’s trench line.
 
Apparently the enemy had been watching how our patrols left the trenches: we had a camouflaged opening in the barbed wire and a narrow foot path that skirted the mines dotting the hillside. The Chinese ambushers had silently made their way to the base of the hill, unseen and unheard by the Marines in the trench just above. The Chinese caught my men as they passed single-file through the wire. Our guys never had a chance.
 
The burst of burp-gun fire took me by surprise. Standing outside the trench, I went into a defensive crouch. My heart raced as the adrenaline kicked in. They can’t be this close, I thought.
 
We fired blindly into the darkness and called for mortar illumination. But it was too late; the fight was over in a few minutes. The Chinese had come and gone and left four of my Marines dead.
 
We pulled their bodies back through the wire and into the trench line. I had violated a prime law of combat — avoid predictability — and these men had paid for my stupidity.
 
One of them was my platoon sergeant, Harold Wagner, a West Virginian who was leading the patrol. He had taken three rounds to the belly. We had become very close and I had let him down. The memory of his death still haunts me. Before his body was hauled to the rear, I at least had the privilege of closing the lids over his sightless eyes.

In other words, not Anotherwords

Basic principles which have been proven over hundreds of years still apply, your bullshit notwithstanding. Sun TzU is still the greatest primer on war (or chess) ever written. Your premise seems to be that the shock of unpredictability will overcome the problems you create for yourself by violating proven principles. Bullshit. It is against the arrogant, creative patzer that good solid basic principles prevail.

When enemy advances retreat.
When enemy retreats, attack.
When enemy pauses, harass. - SunTzu
 
You seem to think that your "brilliant" inventiveness means you can just throw the book away. You will win a few games and then someone will play you who develops early, controls the center, manages the clock, creates outposts, connects his rooks, avoids hanging pawns, places his bishops on the diagonals, keeps his queen near the center and grinds you to dust. He will pile up the small advantages which accrue to the solid positional player and counter-punch you to death. And when your hair-up-the-ass attack falls apart you will evaporate... Even you Korean officer read and respected the manual of infantry tactics.
