You find all sorts of beautiful and interesting positions.

Keep it up.
I'll try to keep superior's advantage within sweetspot zone, In other words not too much nor winning advantage - somewhere in between +0.50 | +1.50 range. Note +1.50 evaluation is hardly sustainable for defending engine.

Eval: ~ 1.00

Defending positions like this is reminiscent
of the job of a bomb-disposal expert: any false
move may be your last. Making the right choice
in the present situation is not simple. Over the
board, the correct decision may be suggested
by a process of elimination. The point is that if
there are several candidate moves but nearly all
the lines lead to clear defeat, while just one of
them offers some light at the end of the tunnel,
then this is the one to go for. If it doesn't help,
and we lose - well, hard luck! The decisive
mistakes must have been made at an earlier
stage. In exactly the same way, of course, a process
of elimination may be applied to positions
where we are looking for a path to victory.
