To be fair I think the program has improved. It very nearly had you in
this game (and if it had been properly tactically aware at move 30 it
should have won). That is a big change from slowly but inexorably
losing (which was most often the case in earlier incarnations).

Here is another game between Help Bot and Normal Level.

I do not understand why in 18th move Normal Level do not take the Rook
with Bishop instead it took a Pawn?

Why Normal Level took Knight giving its Rook in 24th move?

It looks like Normal Level is doing a lot of calculation mistakes.
What do you think?
