Actually, I wanted to demonstrate a CT800 loss, against an opponent I consider as superior. However, the CT800 refused to just do me the favour and lose.
This game begins as a Slav Defence until suddenly the Vancouver starts thinking that the Queen’s Gambit is a real gambit.
The conventional wisdom is that Black may take the pawn and would like to keep it, but is not able to do so. Trying to hold on will usually bring down all kinds of nasty things upon Black if White plays correctly, and this game is no exception.
Besides, a major point of the Slav Defence is that Black wants White to take on d5, which enables Black to take back with the pawn on c6. The Vancouver keeps the awkward c6 pawn, takes the non-gambit, and hell breaks loose.
The Vancouver just loses its touch and makes some suboptimal moves here and there, but the overall problem is the total lack of perspective.
The CT800 uses its development advantage, drives the black king around and scores the game without committing an error. The Vancouver rather resigns than facing a hopeless endgame.
