Re: Discovered drawish position
Latest K defeated H6, both contempt at zero. H6 with twice as much time.

Re: Discovered drawish position
Hi Jon!
I seems 30'+30" was too little hardware- time here, even with doubling White's part.

Funny enough at the end of this output- line White's in advantage.
With 24...Rb4 instead of ...Qxh4 (?) it's Black's eval of about -4 pawns.
Made a little Backward with asmFish of your game, there it seemed that Houdini blundered at 13th. Even if I guess, with enough time for White Black will lose anyhow, probably yet not as quickly as Houdini did.Nordlandia wrote: ↑Sun Jul 15, 2018 11:10 pm [pgn][Event "DESKTOP-N1IDKRV, Rapid 60m+60s-30m+30s"] [Site "Expert-Desktop"] [Date "2018.07.15"] [Round "1"] [White "Houdini 6.03 Pro x64-pext"] [Black "Komodo 12.1.1 64-bit"] [Result "0-1"] [Annotator "-1.13;-1.18"] [SetUp "1"] [FEN "r2rq1k1/pp5p/4b1p1/5p2/3Np3/2B1P2P/PP1Q1PP1/3R2K1 w - - 0 1"] [PlyCount "108"] [TimeControl "1800+30"] 1. b3 {-1.13/30 167 Both last book move} Rac8 {-1.18/32 136} 2.
