| Jun-25-16 | | AlicesKnight: I saw the first part including ....e5 and the need to get the BK out of the corner, but missed (like <scholes> and <al wazir>) the detailed use of the Black QB to achieve this. A complex problem with every piece having an active role in all areas of the board. |
|
| Jun-25-16 | | dick50: White can prolong the fight with 36 Bg1 (instead of Qg1) The game would proceed as
36 Bg1 Rxg1 37 Kxg1 Rxg2 38 Kxg2 Kg7 39 Nxd5 c2 40 Rc4 c1(Q) 41 Rxc1 Bxc1 now white may hope for draw if he can exchange his two pawns and Knight for black pawns e and f |
|
| Jun-25-16 | | gofer: We are given a POTD, where we are 3 pawns up, two of which are passed and one of those is two away from promotion.
Even more interesting is that white's king is in a mating net and white has a weak back rank of its own. So what is so "Very Difficult" for black? Well the problem is the weak a1-h8 diagonal. White threatens all sorts
of nasty tricks if we allow Bd4+ and they get worse it that is followed up by Qg3/Qh4/Qxd4+ etc So how to strengthen the a1-h8 diagonal and keep the bank rank weak and keep our mating net?! <31 ... Qxf1+>
<32 Qxf1 ...>
It is interesting to note that the immediate Rh1 is a disaster. 32 ... Ra1
33 Bd4+ e5
34 Bxe5+ f6
35 Bxf6+ Rg7
36 Rc8+ Bc8/Be8
37 Rxc8#/Rxe8#
So we still need to strenghten the a1-h8 diagonal.
<32 ... e5>
But, the whole point of this move is not only to stop Bd4+, but also to allow Bh3, which is immune due to white's back rank weaknesses!! <Once> we have played our <GOOT>, it is white that needs to find a good move! 33 Rb7 Bh3
34 Qe1 Bg2+
35 Kg1 Bxf3+
36 Kf2 Bxh5 
33 Rg4 Bxg4
33 Rh4 Ra1
33 B anywhere Ra1
33 Qe1 Ra1
33 h4 Ra1
I think white's best try may be...
<33 Nf6 Bh3!>
34 Qe1 Ra1
After this I am going to have to check...
~~~
I didn't see <34 Rh4> which is a nasty little trap! 
click for larger view...but black found a solution to exploit white's weak back rank.
But I think that perhaps white missed the chance of a draw! 34 ... Bg2+
35 Qxg2 Ra1+
36 Bg1! Rxg1+
37 Kxg1 Rxg2+
38 Kxg2 Kg7
39 Nxd5!
click for larger view39 ... c2
40 Rc4 c1=Q
41 Rxc1 Bxc1
click for larger viewNow this isn't definitely a draw, but its a lot closer than
where we started off!
Just as <dick50> and <dfcx> have pointed out too... <I wonder what an engine would make of this, surely white has no chance
in this position and black must have a clear win - which we ALL have missed?!?!> <31 ... ?> |

| Jun-25-16 | | WorstPlayerEver: I guess it's a rarity. Rather would learn to play decent chess and not play variations 3 pawns down with White ;) |
|
| Jun-25-16 | | JohnBoy: Totally missed 33...Bh3. It sure looks to me like <gofer>'s line is the best white can hope for. Great play from black, and nice try by white w 34.Rh4. Two sluggers going at it! |

| Jun-25-16 | | catlover: I saw 31...Qxf1+, but kept looking for a way to make 32...Ra1 work. Congratulations to anyone who saw 32...e5. |
|
| Jun-25-16 | | catlover: The fact is, there were all sorts of good moves to be found for black in this combination. Fine play by Pomar Salamanca. |
|
| Jun-25-16 | | Carlos0012358: Great riddle today!
One might think that after 32.Qxf1 the obvious continuation is 32....Ra1 to pin the black Q, but that in fact would be a fatal error because
32..............Ra1
33 Bd4+ e5
34 Bxe5+ f6
35 Bxf6+ Rg7
36 Rb8+ Bc8
37 Rc8#
Therefore, 32....e5 was right! At this point white is done. 36.Bg1 may have been better than Qg1, but all the same. The end is near. |

| Jun-25-16 | | agb2002: Black has the bishop pair for a bishop, a knight and three pawns. White threatens 32.Rxb5 and 33.Bd4+.
The simple 31... Qxb4 fails to 32.Bd4+ Rg7 33.Qg1 Qxd4 (33... Rag8 34.Bxg7+ Rxg7 35.Qxg7#) 34.Qxd4 Rag8 35.Nxg7 (or 35.Rg1 c2 36.Qxb2 c1=Q 37.Rxc1 followed by Nxg7, but not 37.Qxc1 Rxg1+ 38.Qxg1 Rxg1+ with a won ending for Black) 35... Rxg7 36.Rg1 c2 37.Qxb2 and White wins. -----
Another option is 31... Qxf1+ 32.Qxf1 e5 (32... Ra1 33.Qxa1 Bxa1 34.Bd4+ Rg7 35.Rb8#): A) 33.Bf2 Bh3
A.1) 34.Qxh3 Ra8+ and mate in two.
A.2) 34.Qe1 Ra8
A.2.a) 35.Qg1 Bg2#.
A.2.b) 35.Bg3 Rxe1+ 36.Bxe1 Bg2+ 37.Kg1 Bxf3+ 38.Ng3 c2 39.Bd2 Bc3 wins. A.2.c) 35.Qxa1 Bxa1 - + [B+3P vs N] (36.Nf6 c2 37.Be3 Rc8 38.Nxd7 c1=Q+ 39.Bxc1 Rxc1#). B) 33.Rd4 Bh3 34.Qe1 Ra1 35.Rd1 Rxd1 36.Qxd1 Bg2+ 37.Kg1 Bxf3+ 38.Ng3 Qxd1 - + [R+B+4P vs N]. |

| Jun-25-16 | | YouRang: Today's (Saturday) puzzle: 31...?
click for larger view
At first glance, I see the "obvious" 31..Qxb4, but then noticed that I have a problem with 32.Bd4+, because I have a pathetic cornered king. So, after a (too long) period of time, I noticed that I have a queen-pinning tactic if I grab the other rook <31...Qxf1+! 32.Qxf1>
click for larger view
Now I threaten to regain the Q with 32...Ra1! And if I exchange queens, then it looks like I can have chances to promote my c-pawn. But I still have the problem with the bishop hitting my cornered king, so I have to stop that first. Can I do that while still preserving my chance to play <...Ra1>? Yes, because white also has a pathetic cornered king! I can prevent Bd4+ most easily with <32...e5>, and white is still helpless to avoid 33...Ra1. ~~~~
At this point, I thought I had solved it (and I did pretty well), but checking with the computer, I see that white's best continuation is <33.Nf6!>, and then I had better find <33...Bh3!>, for reasons that I would never have found back at move 31. Maybe not at move 33 either... |

| Jun-25-16 | | morfishine: <Jimfromprovidence> Not 35.Nxg8 but simply 35.Nxd7 winning a piece threatening 36.Nxe5 |

| Jun-25-16 | | YouRang: <Jimfromprovidence: I am still trying to ascertain why 33...Ra1 does not work. What follows should be 34 Qxa1 Bxa1 35 Nxg8 Kxg8.

This creates back rank problems for black, and white uses the ensuing tactics to spoil black's winning chances. Here is the engine line: <36...f6 37.Rb7 Be8 38.Rg7+ Kh8 39.Rg1 Bb2 40.Bg7+ Kg8 41.Bxf6+ Kf7 42.Bxe5 Ke6 43.Re1 Kd7 44.Re3 Bg6 45.Kg2>

| Jun-26-16 | | The Kings Domain: Initially got the puzzle right but didn't see the logic behind it, so I thought 31) ... Qxb4 was the answer. This is the first game I've played by Pomar and it's a fine introduction to his skill. |

 | | steinitzfan: This game made quite an impression on me. I've kind of had it on my mind since it was puzzle of the day a few days back. It combines an odd mixture of aggressive tactics with damage control. |
