Oct-03-18		patzer2: US TV networks don't air week old reruns. Surely chessgames.com can do better than this.

Oct-03-18		stacase: The odd thing is I don’t remember this from last Wednesday. Well whatever, it’s way too easy for a Wednesday.

Oct-03-18		TheaN: Ok, good to see that I'm still mentally capable to remember that I posted on this last week with the failed try 35.Nd5. Typically, I DID see 35.Bxg6+ near instantly just before realizing it's a repeat.

Oct-03-18		houtenton: gangy goody jacky brash vatat dutch crunk, now I took the time once to read this poet (?) since there is nothing to do today. Sadly, time to take over.

Feb-18-25		mel gibson: The first ply was easy but it looked like the Black King might escape. Stockfish 17 says mate in 11: 35. Bxg6+ (35.

Feb-18-25		King.Arthur.Brazil: The king saw this move: 35. Qe7 gxf5 36. Qf6 (threats 37. Rh8#). Rc8 38. Qa1+ 38. Kg2 Qxc3 39. Qxf7+ Kh8 40. Rxh6# or Qa7 39. Qxh6+ Kg8 40. Nd5... with several attack choices.

Feb-18-25		saturn2: It should be 35.Bxg6+ Kxg6 (Kg7 36.Bh5) 36.Qg4+ Kf6 37. Nd5 mate

Feb-18-25		takebackok: Had a think Tuesday, easy 35. Bxg6+ now of course not Kxg6?? Qg4+ and mate. So, 35...Kg7 now 36. Qe7! threat Rxd6 &/or Qxe5+ don't see a real reply/defense.

Feb-18-25		vajeer: Interesting that SF gives it mate in 11 as per Mel's post. After 35. Bxg6 Kg7 36. Qe7 I tried 36...Qb7 and engine gives it mate in 27 (not sure what the latest version of SF will come up with). But if this is the case I may have found an improvement over SF's line ;-) although it may count for nothing as black is still losing. Here engine suggests 37.Qxe5+ f6 40.Qd5 Kxg6 41.Rxd6 enough to resign here. click for larger view

Feb-18-25		stacase: No think Tuesday. Yesterday, not so much.

Feb-18-25		TheaN: For once I'm better than my former self (from 2018 though, so not necessarily that long ago) as I took the time to analyze the defensive options after <35.Bxg6+ Kg7 (Kxg6? 36.Qg4+ Kf6 (Kh7 37.Qg8#) 37.Nd5#)>. The problem is, the White pieces coordinate decently enough but the Black knight is incredibly annoying in keeping the position intact, whilst meanwhile Rxc3, Qa1-c3 and if the knight moves Rc1-Qf1 are looming. Came up with the meh-looking <36.Bh5> to hold on to the bishop and meanwhile bolster the defenses, and frankly I don't really see a way to go for Black as it's almost zugzwang: click for larger view It keeps pressure on all points in the Black position that are an issue: f7, d6, g4 and d5, and defending the one square in the White position which is d1. This shows after the apparent best <36....Rxc3 (Qa1+ 37.Nd1 +-) 37.Qxd6 Rc1+ 38.Bd1 +->. Maybe not the most flashy, but it works.
