Good night all,
the Chinese bomber L6 v2 teaches the CT800 what chess is all about
60 moves are enough to crush it
twice!!
In the first game playing White, the L6-v2 shows how to dominate the center, gain space, open lines and coordinate attacking pieces, all aimed at the ennemy King's corner. A real show of force! I knew it plays very strong chess, but up to spank the CT800 in such a way, I didn't guess it. Much impressive!
The second game starts balanced for the CT800 now playing as White, on par for roughly 20 to 25 moves. Then the L6 plays a Pawn move that looks rather minor but actually enables a thundering threat onto the poor CT800 King, unsufficiently sheltered. The CT800 fails to immediately provide additional support, and collapses.
A couple of facts to be reminded, about the L6-v2:
- it is a dedicated chess computer, not to be confused with some boards requiring a remote engine on a powerful smartphone or PC;
- each and every move is played
