How Deep Do You Look?

The depth of vision/calculation between players of different strengths, is a topic that comes up pretty regularly on RHP. Last time this week.

The thing that has become apparent (to me), is that the weaker players tend to say they look very deep (5-8 moves or even deeper), while the stronger ones look only a couple of moves deep (2-4). Obviously there are exceptions in both groups, but the tendency is quite clear. Clear enough to make me a bit suspicious when a strong player claims to look 5-7 moves deep on average.

It could be because weaker players only think they see that deep, when they actually crack 1-2 moves deep, and it's probably partly true. But the real reason, in my opinion, is that weaker players have the misconception that you need to calculate deep to be strong, which simply isn't true (excluding exceptions like forced variations & endgames). The better I've become, the less deeply I calculate (on average). Nowadays I almost never calculate deeper than 2 moves in CC, and I can remember only 1 single time when looking 5 moves deep (against a 2300) would've made a slight difference (he managed to equalize my slight advantage in the endgame).

The errors happen 1-2 move deep, and the overwhelmingly most common one is underestimating a move that you did look into. And by underestimating I mean direct consequences that are blindingly obvious once you see that move made, not consequences that lie deeper. "Oh hell, that pawn move blows my center to pieces" is what happens. -You correctly assessed that you won't lose material, fall into a tactic or a mate, but you missed the amount of trouble (which may or may not be survivable) the move caused.

Another thing which I think strengthens the misconception, is that weaker players absolutely uncritically love what engines tell them. They see engine evaluation as 'objective truth', which it's not. It's a subjective numeric approximation, which has only one strength: It's not susceptible to tactical errors. - An engine can't tell shit about a position without calculating, or at best things like: "A doubled pawn is -0.2", which may not be relevant at all. A strong human can tell enough to beat weak engines.

And because weaker players know this specific kind of 'objective truth' is reached by extremely deep calculation, they think aping that will magically give them greater understanding of the position, which it generally won't.
