| Dec-04-14 | | Gilmoy: <14.Ke7> smh ... I've not seen such bravery After <19.Nxe5!> gxh3?? 20.Nxd7+ Kd8 <Be5 21.Bxe5 egad> 21.Bxf6+ Kc8 22.Nxc5+ <covers b7> Qd7[] 23.Nxd7! <23.Bxd7+ leaves White with a brittle protection chain> The wreckage is ... legendary. Both Rooks, a discovered check, down two pieces, White is safe. And 3 pawns.

| Dec-05-14 | | Nerwal: Of course Black's moves are just ugly, but the position looks far from easy to handle. 12... 0-0 is met by 13. ♗g5 ♕a5+ 14. c3, and 12... ♖b8 doesn't solve anything since 13... ♖b4 is met by 14. c4. Gulko, a french specialist and an old-school player, hardly did better : Yudasin vs Gulko, 1993 |

|
| Jan-13-16 | | dumbgai: Didn't get the solution, even though I had evidently looked at the game in the past. Lenderman is a strong player but here he gets demolished like a beginner. |

Anyway, Wednesday puzzle here, the part of the week where the puzzles start getting out of my zone. Here, I thought of 2 lines: The first was 19.Nxe5, but I quickly discarded it due to 19...Qxh3, not knowing that white will crush black starting with 20.Nxd7+. King in check, discovered attack on knight, which is pinned to rook, etc. I also considered 19.Bxg4, but not sure what the point of that is. |

 | | Phony Benoni: That took a while. I kept looking for a way to pin Black's queen with a knight. With so much en prise, it is often wise to search for a counter attack. Here 19.Nxe5, with a tempting double check should Black take the queen, suggests itself. It seems like none of the double checks work out, but then I considered <19.Nxe5 gxh3 20.Nxd7+ Kd8> (20...Be5 21.Bxe5 forking everything with a possible 22.Bf6+ in reserve) <21.Bxf6+ Kc8 22.Nc5+>, and I like that. There are plenty of other variations, but this looks like the idea. |
|
| Jan-13-16 | | Ehrenfest: I got stuck with the double checks which did not pay out, and missed 20. Nd7x.
Not easy at all |
|
| Jan-13-16 | | patfoley: Instead of Qh4, Nxg4 works as well. |
|
| Jan-13-16 | | diagonalley: figured the likely first move... but the continuation/s were a bit murky... (harder than usual for a wednesday) |
|
| Jan-13-16 | | Nick46: My excuse is that I still haven't got back my real chessboard and wooden pieces. |
|
| Jan-13-16 | | cocker: I found this one very hard, in fact impossible. |
|
| Jan-13-16 | | Eduardo Leon: I got stuck trying to make 19.♘xe5 gxh3 20.♘g6+? work for about half a minute, then realized there's another way to cover f8: 20.♘xd7+!. At this point, it's pretty much game over. Not capturing the queen simply allows 20.♕h4, with the deadly threat 21.♘xg4+, and again it's pretty much game over. |
|
| Jan-13-16 | | morfishine: <19.Nxe5> |
|
| Jan-13-16 | | Ratt Boy: Does anybody think that 14...♔e7 is a good move? |
|
| Jan-13-16 | | wooden nickel: 19.Nxe5 was easy to guess since the queen and bishop aren't really hanging (at least not without compensation), the more challenging part was
after 19... BxNe5

<Nick46: My excuse is that I still haven't got back my real chessboard and wooden pieces.>
I used my real chessboard with wooden pieces! |

| Jan-13-16 | | patzer2: Today's Wednesday (19. ?) puzzle is tougher than our usual midweek selection. Three White pieces are en prise, so it would seem a desperado-like move sacrificing the Queen is necessary. The most active desperado I could find was 19. Nxe5! I looked at 19. Bxe5? as an alternative, but after 19. Bxe5 gxh3 20. Bxd7 Kxd7 21. Rad1 Rhg8 22. Bxd6 Rxg2+ 23. Kf1 Qxd6 24. Ne5+ Kc7 25. Rxd6 Kxd6 26.
Nxf7+ Kd7  (-8.07 2 21 depth, Deep Fritz 15) Black turns the tables and steals the win from White I visualized 19. Nxe5 (19. Bxe5? gxh3 20. Bxd7 Kxd7 ) 19... Bxf5 (19... gxh3 20. Nxd7+ Kd8 (20... Be5 21. Bxe5  ) 21. Bxf6+ Kc8 (diagram below) 
click for larger viewand settled on 22. Bxh8 (-5.85 @ 18 depth, Deep Fritz 15). However, what I missed in calculating that line is 22. Nxc5+! (diagram below) 
click for larger view22...Qd7 23. Bxd7+ (-15.60 @ 24 depth, Stockfish 5SE) is a much stronger continuation than 22. Bxh8 . |
|
| Jan-13-16 | | patzer2: For a possible improvement for Black, I prefer 9...Ne7 = as in C Balogh vs Ngoc Truongson Nguyen, 2014. The computers agree with <Gilmoy> that <14...Ke7?>  to (-1.68 @ 23 depth, Komodo 9.01) was much too <brave>. Instead, my computer indicates 14...c5 15. Bb2 Bc6  (+0.52 @ 22 depth, Deep Fritz 15) keeps Black in the fight. |
|
| Jan-13-16 | | scholes: This was atleast saturday level. |
|
| Jan-13-16 | | patfoley: After 19 ... Bxe5, white can win an exchange and a pawn with 20 Bxe5. Given that the straightforward Nxe5 wins without subtlety in most lines, the one trick of the puzzle is to see how well the minor pieces coordinate after B takes the Q. |
|
| Jan-13-16 | | saturn2: I got lost in too many variations. After 19 Nxe5 one has to calculate also 19...Kf8 for instance.
As far as I see white wins only two pawns which is nice but not enough for a puzzle solution.
For instance 20 Nxd7+ Nxd7 21 Qxg4 Rg8 |
|
| Jan-13-16 | | patzer2: <Saturn 2> After 19. Nxe5 Kf8 20. Nxd7+ Nxd7, the computer gives a White win with 21. Qh4! (+9.03 @ 21 depth, Deep Fritz 15). After 19. Nxe5 Kf8, White can also win with the immediate 20. Qh4! (+9.15 @ 20 depth, Deep Fritz 15). |
|
Jan-13-16
 | | Jimfromprovidence: Another interesting line to work through is after the text 19 Nxe5 Bxf5 20 Qh4. Black, anticipating 21 Nxf7+, tries 20... Rhf8.
