White is led by Seawall, black by Kimbo.

Kimbo, is also a relatively young chess engine that is being vigorously developed, with new versions published frequently.

On the chessboard, a position that seemingly can be judged more favorable to black. The white Knight is tied up and seems to stand at a loss.

White's move.


A brave decision! At the cost of Rook, Seawall opens the position and turns on his figures to directly attack the black King's position.

Kimbo did not disdain Rook and "free" took it for himself.

White's response is strong: 20.Bxh6.

The black King's fortification is melting away.


Seawall opens the diagonals for white Bishops. Will black manage to save this game ?

The desperate attempt to shield the black monarch does not carry the expected result. White opens more lines and includes more figures in the direct assault of the black King.



Almost all of the white forces are concentrated on the King's wing - where the Kimbo King is desperately watching events unfold.

Is it time to give up?


Yes, Blacks can no longer turn the game in their favor.



Seawall concentrated his attack so hard that the game ended in a matte!
