Mini-TCEC Season 2: Analysis

Post by bastiball »

Here is the thread where I'll post some games analysis. :D

Here's a game 1 from QL. Uralochka loves maneuvering the knight where it make its pieces active and such that Ura converted it to a win.

A game 2 from QL with Ura plays black

Both engines play flawlessly in Nadorf which resulted in an interesting draw where everything could go in the middle game and endgame.

Game 3 from QL Rebel played white and Nawito played Black

After black move in Qc7, he's on the verge of losing. Rebel took it a chance and took control all over the dark squares.

Last Analysis for tonight. Game 4 from QL where Rebel played black.

At the move 15, Black gained advantage, where it started to collapse the queen side of White which Black has more pressure by pushing with the b pawn.
