|Jun-23-18|| ||patzer2: Since it was a Saturday, where the puzzles are typically difficult, it wasn't hard to figure the combination involved the exchange sacrifice and pinning combination 14. Rxe6! fxe6 15. Re1 Rd8 16. Bxe6 +- (+3.12 @ 23 ply, Stockfish 9 analysis of move 14...?) to expose and attack the weak King position.|
What I did find difficult was (1) initially recognizing the Rook sacrifice 14. Rxe6! was clearly winning and (2) finding the strongest follow-up moves.
Movsesian no doubt recognized 14. Rxe6! was clearly winning. For me, 14. Rxe6! was an unclear but promising exchange sacrifice. In the follow-up, I managed to find White's 17. Qe5 +- (+3.33 @ 32 ply, Stockfish 8). However, in analyzing the game, I found the follow-up easier after the equally strong computer choice 17. Qd3 Kf8 18. Qg6 +- (+3.63 @ 32 ply, Stockfish 8).
P.S.: For a Black improvement, I'd start early in the opening. IMO 4...d5 is premature and slightly weakening. Apparently most masters agree as our Opening Explorer indicates 4...d5 is rarely played at master level. My preference is the popular move 4...b5 as in Black's recent win with it in Y Zherebukh vs Caruana, 2018, 2018.
Black's decisive mistake came only 9 moves later in the opening with the natural looking move 13...Be7?, allowing today's Saturday puzzle solution 14. Rxe6! +-. Necessary instead was 13...Rc8 14. Qe5 ⩲ (+0.55 @ 34 ply, Stockfish 8).
|Jun-23-18|| ||patzer2: It appears the follow-up moves 17. Qe5 +- and 17. Qd3 +- are indeed equally strong. Stockfish 8 @ 40 ply indicates they transpose after 17. Qe5 Kf8 18. Qf5 +- (+3.41 @ 40 ply) or 17. Qd3 Kf8 18. Qf5 +- (+3.29 @ 40 ply).|
|Jun-23-18|| ||agb2002: Black threatens Bxh3.
White can take control of the light squares and force the black king to stay in the center with 14.Rxe6 fxe6 15.Re1.
White will capture the e-pawn (15... e5 16.Bxd7+) and combine the attack against the d-pawn with threats against the king.
For example, 15... Rd8 16.Bxe6 Qc6 17.Qd3 Kf8 18.Qg6 Qe8 19.Qf5 Qc6 20.Be5 d4 21.Bxf6 Bxf6 (21... dxc3 22.Bxg7+ and 23.Qf7#) 22.Nd5 Rxd5 (due to Nxf6) 23.Bxd5 Qc7 24.Qe6 wins.

|Jun-23-18|| ||landshark: White had to have seen the exchange sac when he played 10 Bh3 - I would not likely play such a move in a real game - but situations like this is how you learn. Once it was put in front of me as a puzzle, after long thought I finally realized the opportunity provided by the exchange sac 14.Rxe6. In a real game, no matter the opponent, had I seen it I'd have played it because it leaves you in the driver's seat with excellent pressure for the material. As for calculating the rest of it - past move 17 forget it. Just not there yet as a player - maybe never will be...|
|Jun-23-18|| ||saturn2: Found the first two moves prevent black from casteling to neither side.|
|Jun-23-18|| ||CountryGirl: Nice exchange sac by the alleged 'chess tourist' :)|

|Aug-14-18|| ||dragonfish1803: Does anybody know what is going on with these daily puzzles ? No way can this one be described as easy. Easy is zap zap mate. The first three moves of this are fairly obvious for a reasonably strong player but not at all for a weaker player at whom the very easy and easy positions used to be aimed.
It also appears that previous positions are reappearing under a different category; I have a feeling this one has appeared before as a Friday or Saturday puzzle.
Anybody out there have any thoughts about this ?|
|Aug-14-18|| ||Huddsblue: Come on Chessgames, this is another a Saturday or Sunday puzzle in the early week. What's going on?|
|Aug-14-18|| ||erimiro1: Is that easy? 3 first moves were easy to see, almost intuitive, but needed a concrete prove, that was not easy at all to find.|
|Aug-14-18|| ||HaydenB: Agreed with the previous 3 comments. Goes to show how difficult it is to select these daily puzzles and have them be what readers expect. Bad enough that we lost Alberto Artidiello 3 and a half years ago, now with Daniel Freeman gone as well it seems their labor of love Chessgames may not be far behind. RIP both of you and thank you.|

On July/24/2018 the last living Co-Founder of www.chessgames.com passed away at age 51. The other founder Alberto A. Artidiello passed away in March of 2015 at age 56. May both rest in peace and may chessgames.com long outlive us all.
|Aug-14-18|| ||dragonfish1803: Personally it doesn't bother me if there are no more very easy to medium easy positions as they don't present any challenge to even an average club player. But in that case why not just abolish the categories and stop setting reasonably challenging positions like today's under the heading of easy ?|
|Aug-14-18|| ||groog: I hadn't a clue.
Looking through the comments I see it was originally a Saturday puzzle, no wonder it was difficult.
|Aug-14-18|| ||hdcc: The first thirty seven moves played themselves; perhaps by the time we get to "insane" this week there'll be something a tad more challenging.|
|Aug-14-18|| ||Jimfromprovidence: Here's a puzzle more suited to a Monday or Tuesday. BLACK to play and win, move 36.|

|Aug-14-18|| ||lzromeu: After tuesday and monday puzzles, I m afraid friday's puzzle.|
|Aug-14-18|| ||Bobby Spassky: It obviously is going to take a while for chessgames to get back on its feet. The person who took over this website has a tough job. The plan for a successor was not well done.|
|Aug-14-18|| ||PhilFeeley: Exactly which part of that was "easy"?|
|Aug-14-18|| ||morfishine: <PhilFeeley> Now thats funny! lol|
|Aug-14-18|| ||gabriel25: Perhaps a compilation of different ideas over the qualities each day of the week puzzle should have would help whoever takes the job.
I seems everybody likes Monday very basic and short and Sunday as complex as we can take.
I don't have any more ideas because I am late arrival to GC.|
|Aug-15-18|| ||Mayankk: Nice one JFP. I think you will be a worthy administrator for this website as your choice of puzzles is quite excellent.|
