there you could be right...  I was speaking "in the context of the
match" which means you have to commit to a plan, and you have to do
it with a fixed 10 second/move limit, plus however much of your 10
minute "cushion" you are willing to invest *right now* as opposed to
*later*...

Of course, at 40/2, both sides would have played differently, which
means that trying to second-guess either side (given a longer time
control)
would be hopeless...
