When playing bullet, you always need to keep an eye on tactics and patterns,
much of it is intuitive, for example in this game I didn't work out all the
lines as it would be prohibitively costly.

So you look at the outline and check the basic refutations as fast as possible
which isn't easy, as you grow older...so many of my combos are lost on time or
inaccuracies, or the failure to follow through correctly.
