Subject: Easy v Vlad

Below are two games between GetClub's Easy level and Vlad, once of the
Chessmaster personalities who is rated approximately 1850 USCF. Each
side had White once. The result is 1.5-0.5 for Vlad.

The first game was a complete strangulating win for Vlad, giving
checkmate in only 33 moves. Vlad uses rather unorthodox openings, and
was not doing well as of the first few moves of the game. However,
Easy forgot what "tempo" means and played 6...Ng4 and 8...Nd4. After
that, it was simple for Vlad to continue the squeeze and win,
exploiting a very useful pin on Easy's d5 pawn.

Easy had a simple win in the second game, thanks to some poor moves by
Vlad, but failed to make the obvious move of 105.Kxh5. This drew the
game. I ended this game early because Vlad uses endgame tablebases and
the position was a guaranteed draw when Easy played (for some
inexplicable reason) 105.Kg6 instead. Yes, I played through 105 moves
with Easy -- never again. Easy took about 2.5 hours to make all of its
moves; Vlad took eight seconds.

So, it seems pretty clear to me that Easy does not play anywhere near
the 2350+ that Sanny claims. At best, given the fact that I've only
played two games, I would say that Easy is somewhere between 1700-1900
USCF. Easy is significantly stronger than Beginner, which I would
estimate at about 1200 USCF.

This was all very tedious, so I'm done. Sanny, please don't bother to
say that the above move (105.Kg6) was "a bug that has been removed and
now GetClub plays twice stronger".

Who is Merlin??? I think you played with some other program.

You said easy missed 2 tempo by playing 6...Ng4 and 8...Nd4? What is
Tempo? How to know if a move is loss to tempo?

I probably should clarify how Vlad works. It has a search depth of 3
(about 1/4 of what Easy searches on average, as far as I can tell from
the interface). This is why it moves so quickly.

The second game shows how an engine with such a low search depth, no
matter how strong, has little ability to make a plan or take advantage
of an opening. The game was very exhausting and discouraging to play
through, not just because of the time involved, but because Vlad
refused to go for the kill that Easy offered it on many occasions.
