Re: Stockfish Shines Against DR4
Stockfish has indeed become quite strong and R4 has IMHO 2 weaknesses I can readily identify which cause the vast majority of losses. Number one of course is improper bishop evaluation in some instances where the bishop is blocked or rendered useless, and the other is that King safety (although highly improved from R3) is still an issue where a smother attack by loading pieces against its King is only realized as dangerous when it is too late. While very fast hardware or LTC might eliminate problem #2, problem #1 simply needs an improved evaluation with regards to "bad" bishops.
By the way is there a way to collect those games as one pgn file to take a look at the games? Thanks in advance.
