True, but if you play over the rest of the game it is the start of a faulty
plan. The game continued Kf5 Kb5, Ke4? ... so I should have included that
position also. Here's my guess as to what happened. Genius initially
had Kxe5 as the initial choice but sees that it leads to a draw. Thinking
it could win it chooses an alternative move, Kf5, but lacked the time
to fully appreciate that this is no better. Someone explained something like
this once, when a program takes a big drop in its eval it is left to
scramble for another choice with little time on the clock to adequately
come up with a decent move. Kf5 is just silly.
