|Jul-10-08|| ||johnlspouge: Thursday (Medium): Black to play and win.
Material: 2Bs for B+N. There are no passed Ps on the board, but Bh5 and Bf2 have created a barrier on the e-file the White Kd3 cannot cross. The White Pg2 is vulnerable to the active Black Kg5, so Black has the initiative, dark-square control, and more active pieces. Black must respond to the threat 51.Nxh5, which would leave a drawn ending with Bs of opposite color.
Candidates (50…): Bf3
50…Bf3 threatening 51…Bxg2 then eventually h1=Q
I do not see any defense.
I confess to a certain disappointment: on a Thursday puzzle, I looked hard for greater depth. I thought there must be a swindle, but tucking the Black King out of harm's way with 51.Ne6+ Kf6 was the natural move. I would be curious if anyone could demonstrate a White win after 51...Kg4.
|Jul-10-08|| ||eaglewing: Regarding my example line 61. Ne2 seems to be not enough to draw. A winning idea is Qf1+/Qh3+/Qf3/Qe3 and then there is time for the Kingwalk e5/f6/g5/g4/f3.|
A better defense may be 61. Nd3+ Kd4 Nf4 and fleeing Kf3/g4/g5. Still analyzing.
|Jul-10-08|| ||Jesspatrick: Promoting the h-pawn is one thing. Winning the win afterwards is something else. It's possible for the Q vs N+B+P to slip into a draw without accurate play.|
|Jul-10-08|| ||openingspecialist: Rather simple puzzle but in a game it's slightly different, especially with a player wanting to hold the bishop pair. I(white) recently had a winning endgame I drew due to not finding the right move. can you spot what i failed to spot?

At this position i was thinking drawn.
My clock read 8.32 and it was + 10

h5? seems easy enough. If black takes the pawn, white maintains opposition, if not, he gets connected pawns

Oops, h5 deserves ?? instead of ? as it draws...stupid me. I ran through an engine to check as I was too impatient to wait and Kh6 is the winning move :)
|Jul-10-08|| ||openingspecialist: I played h5 realising it was a draw. We agreed on a draw.|
|Jul-10-08|| ||openingspecialist: Analysing my game afterwards was one GM Ian Rogers who we have had several puzzles from. He was not impressed to say the least and skiped the opening and middle game straight to the last position and told me to play black.|
|Jul-10-08|| ||Marmot PFL: Bf3, capturing or diverting the white g pawn and clearing the way for the h pawn to queen. A little easier than the average Thursday - there were not many alternatives.|
|Jul-10-08|| ||YouRang: A quick scan of the position left me with the impression that this was going to be about promotion tactics, and with that in mind, 50...Bf3 became an obvious try. |
Either the g-pawn takes our bishop, giving our h-pawn a free pass, or our bishop takes the g-pawn, with the same effect.
Other than a knight check, I didn't see any way for white to stop it. Rather easy for a Thursday, IMO.
|Jul-10-08|| ||MiCrooks: This was a pretty obvious one if you have any experience with endgames at all. The key is getting your pawn through to Queen, so Bf3 jumps off the screen at you.|
And this IS an easy endgame. The only fear from Black's side is that you screw around too long and run into 50 move problems. While White's pieces are all defended, a fortress only occurs if those pieces also somehow keep Black's King from approaching (like Kb1, pb2, Rc3 where White can move the rook back and forth between a3 and c3). Even these positions are tricky as if you move them up the board where the Queen can get in behind the fortress crumbles.
In this case, with all the space behind the White pieces, and with no way of advancing a pawn Black wins with a mating attack.
|Jul-10-08|| ||kevin86: This is almost as simple as a Monday puzzle:50...♗f3 looks as elegant as it is obvious;Other than the pawn at g2,no other white piece has ANY control over the lower right quadrant of the board. White's pawn is diverted or lost,and the h-pawn comes in to queen.|
|Jul-10-08|| ||kevin86: In the final position,white is in zugzwang and must move the knight to a position where it will be subject to forks-or white must abandon one of the pawns.|
|Jul-10-08|| ||YouRang: <openingspecialist> Very nice little puzzle there -- Thanks! :-)|
|Jul-10-08|| ||Rama: 30. or 31. b4 ..., jumped off the screen at me. White needs to shut the B's out of his position if he can. Right?|
|Jul-10-08|| ||hamham: Yes, I solved this one entirely in less than 20 seconds, just like I did yesterday. Are the puzzles get easier or am I just getting better?|

It would be nice to shut out the bishops, but 30.b4 (or 31.b4) unfortunately doesn't do the job, since black just goes with ...Bb6, which is arguably an even better square for the bishop. From there, he can find an excellent post at d4.
Also, advancing the b-pawn allows black's one b5 pawn to effectively hold back white's a & b pawns, and those pawns may eventually be juicy targets for black's DSB.
|Jul-10-08|| ||messachess: Very very easy|
|Jul-10-08|| ||dzechiel: <hamham: Yes, I solved this one entirely in less than 20 seconds, just like I did yesterday. Are the puzzles get easier or am I just getting better?>|
Well, we have no idea how good you were when you started, but, if you solved this position entirely in 20 seconds, you must be pretty good now. It took me at least that long just to consider the first move.
|Jul-10-08|| ||234: Wednesday puzzle Jul-09-08 <58. ?> Salov vs J Horvath, 1983|
|Jul-10-08|| ||patzer2: For today's puzzle solution, Black begins a winning passed pawn combination with 50...Bf3!|
|Jul-10-08|| ||TheaN: For those you care, I kinda thought this was Wednesday so instead of 3/3 I obviously have 4/4 XD.|
|Jul-10-08|| ||DarthStapler: Solved it, easier than yesterday if you ask me|
|Jul-10-08|| ||jacklovecaissa: <hamham: Yes, I solved this one entirely in less than 20 seconds, just like I did yesterday. Are the puzzles get easier or am I just getting better?>|
thank you for the good jokes :)
|Jul-10-08|| ||al wazir: <MAJ, Eaglewing>: Yes, I meant 50...Bf3 (and that's clearly what MAJ analyzed). |
I can't refute the claim that wussy spoilsport, Hiarcs, is making, but when I played it out I found that black always promoted a ♙ -- though not always the h-♙.
That doesn't sound very rigorous, does it? Well, maybe I only get half a point.
