Here is a game between Help Bot & Normal Level. See what mistake
Normal did that it lost the match in 60 moves. Since both are very
strong players and they both thought 1-2 min per move so it would need
very long calculations and analysis to find weakness in the game.

ROFL. Casual human inspection shows the first of several mistakes by
"Normal" level.

If you think there was any mistake by Normal Level [Strategical
Mistake] or [Tactical Mistake] then let me know it.

How many do you want listed? It started off OK, but gradually lost the
initiative by making ineffective slow tempo moves whilst Helpbot
played with a purpose. It didn't do anything really silly until 14.
Bf2

This is sufficiently far off the plot that had the program chosen a
move at entirely random from the 38 possibilities it would have a
better than evens chance of improving things over the move chosen. My
instinct is that 14. Bd3 would be very playable (although Shredder
preferred 14. Kg2). It took an overnight run and 12h at 20 ply before
it agreed with my instincts and ranked Bd3 as the strongest move (Kg2
was still pretty good but I don't like it).

14. Bf1-g2{208} Nd7-b6{120}

This is really not a great move for white. It is only 100cp down from
the best moves, but you cannot afford such inaccuracies. It isn't
even in the top half of the move rankings.

17. Qd1-d3{82} Bc8-d7{134}

Helpbot missed a trick here. 17. .... Nxd4 18. Qxd4 Bd7 is nasty for
white.

20. Nc3-d5{88} e6-d5{62}

Why in heavens name is it swapping a N for a P ? The attack here is at
best illusory, at worst non-existent.
Kg2 is probably needed at this stage.

21. Bf3-d5{162} Nc6-b8{56}

I reckon 21. ... Ne7 might be more effective.

22. Bd5-e4{164} Nc4-e5{78}

But Normal is determined to keep making its position worse. Kg2 still
needed.

37. Rh4-e4{82} Be7-g5{190}

Plenty good enough to win, but Nxd4 is faster.

41. Bf2-d4{108} Rc2-c7{206}

Bd4 is another rubbish move. Only 41. Rd8+ stands any chance at all
now.

50. Kf1-g2{138} Rf7-f4{22}
51. Rd4-f4{126} g5-f4{6}

It has definitely got a death wish!

Keeping the rooks on the board and hoping that your opponent makes a
mistake out of boredom letting you snatch a pawn is the only chance
remaining here. Once the rooks are off the two passed pawns protected
by their king are invincible.
