Again, I don't think it's fair to look at that GM game and judge it only by the complexity of tactics or required calculation. If you're not seeing any of the positional considerations as well that underlie the moves you haven't commented on, you're almost certainly not understanding why the GM is playing like they are.
but this is the premise that i wish to test, the relative tactical complexity and it needs to be viewed in isolation, there is no point in clouding the matter with positional concepts at present for we are merely interested in the relative complexity of the variations. I have read Micheal Steans wonderful book but that is something else, here I am trying to demonstrate that there exists a disparity in complexity of the tactics of actual games in comparison to those we meet doing tactical exercises.
I do see your point.
yes its very interesting indeed, thankyou for your comment. It appears to me that tactics are used primarily as a way of subjecting an idea to falsification rather than an end in themselves (this symbiotic relationship between tactics and position alluded to earlier by out friends), we have an idea and use tactics to verify whether it will work.
