|Jan-02-12|| ||backrank: The final combination (19. ... Bc4! 20. ... Bf1!!) is sheer beauty ... the point being 21. Qxf1 Nxg3+ !! 22. Rxg3 Qxf1+ (21. Rf2 Nxg3+ 22. Kg1 Qg2# or 21. Rg1 Bxg1 don't help, either)|
|Jan-02-12|| ||Shams: Both players here were at Lone Pine 1977 so clearly that is where this marvelous game was played. |
<backrank> Yes, a lovely finish from Black's LSB. To attack the Queen twice and decide the game instantly like that is sublime.
|Jan-02-12|| ||King Death: This line against the Goring isn't too testing, but the finish was beautiful.|
I went to most of the Lone Pine events to check things out, but I couldn't have seen this game that year, because there's no way I'd have forgotten it.
|Mar-29-12|| ||Tired Tim: 0505 UK time .... problem said "White to Play" ... It isn't!|
|Mar-29-12|| ||chessgames.com: 12:15am USA time, Problem is corrected now, sorry for those confused at midnight.|
|Mar-29-12|| ||al wazir: Forget about finding the "most forcing move." Find any move for white that doesn't lose material immediately.|
Too bad <CG> screwed up -- it would have been a nice problem.
|Mar-29-12|| ||WannaBe: Isn't 13. g3 better than the Kh1 move (??)|
|Mar-29-12|| ||Tired Tim: < Problem is corrected now, sorry for those confused at midnight.> Thanks ... it's those confused at 5.00 in the morning who have really suffered :-)|
|Mar-29-12|| ||lost in space: no excuses for me, I had Black to play on the sceen and I hav not found the solution. I was playing around with motives like Rd1, Nxg3, I thought also about Bc4 but never ever about Bf1.|
|Mar-29-12|| ||goldfarbdj: I found Bc4 and even toyed with the idea of Bf1, but I didn't find the followup after Qxf1. Obviously I'd looked at Nxg3+ in earlier contexts, but I didn't see that with the white queen on f1 that it worked.|
|Mar-29-12|| ||andrewjsacks: Unusual and beautiful tactic.|
|Mar-29-12|| ||TheoNov: I started at 12:03 on "White to play" and gave up at about 12:10... too bad. However, I did note that Black was threatening 19...Bc4, so I inadvertently got the first move of the real POTD!|
|Mar-29-12|| ||Marmot PFL: Rd1+ is good if we can divert the queen, and Be6 isn't doing much anyway. So 19...Bc4 20 Qxc4 Rd1+ 21 Bxd1 Rxd1+ 22 Rg1 Nxg3 mate. Or 20 Qe1 Bf1 21 Qxf1 Nxg3+ 22 Rxg3 Qxf1 mate.|
A very fast loss for white. Instead of 14 g3, Nb1-d2-f3 looks much better. The knight never moved and at the end white had almost nothing developed.
|Mar-29-12|| ||Hexis: Actually it was more fun to try to find a move for white. I figured that this was one of those drawing combinations since white's position is epically screwed up. I give myself some credit for seeing that Bc4 was in the works. Even if it were white's move, it would have been damned hard to prevent it.|
|Mar-29-12|| ||dzechiel: Black to move (19...?). Material even. "Medium."
I see that black is Peter Biyiasas. I played blitz against him at the US Junior open in 1971 in Portland, OR. He was already very, very good.
This must be tougher than it looks. The natural first move is...
The bishop cannot be blocked (20 Bd3 Bxd3), nor can it be captured (20 Qxc4 Rd1+ 21 Bxd1 Rxd1+ 22 Qf1 Rxf1+ 23 Rg1 Nxg3#). The white queen has to find a flight square.
This is the only place for her majesty to run. But now black follows up with...
With the naked threat of 21...Bxg2#. There's only one way to defend:
But this now allows
21...Nxg3+ 22 Rxg3
The only legal move. But look what's been left hanging!
22...Qxf1+ 23 Rg1 Qxg1#
Note that white's queen side pieces are already set up for the next game. Let this be a lesson for the newbies not to neglect your development.
|Mar-29-12|| ||Marmot PFL: <dzechiel> Well I guess had mate a move too soon. Nobody gonna play on down a queen anyway...|
|Mar-29-12|| ||Qweenlover: Nice puzzle. A very good finish|
|Mar-29-12|| ||Qweenlover: If 20.Q*c4 than 20....Rd1+ is deadly|
|Mar-29-12|| ||M.Hassan: "Medium" Black to play 19...?
One of the most dangerous pieces of Black is the DSB who has a clear diagonal at his disposal and allowing no movement of White King.
d1 square is where black wants to attack through and is guarded by Bishop and the queen, so Black can start his attack by diverting one of them, the Queen:
<if 20.Qxc4 Rd1+ 21.Bxd1 Rxd1+ 22.Rg1 Rxg1#>
20.Bd2 (to cut off attacks of Rooks)
I think this is it.
|Mar-29-12|| ||LoveThatJoker: Very cool! A Peter Biyiasas puzzle: A Canadian IM and a friend of Bobby Fischer.|
<19...Bc4! 20. Qe1>
[20. Qxc4 Rd1+ 21. Bxd1 Rxd1+ 22. Qf1 (22. Rg1 Rxg1# or 22...Nxg3#) 22...Rxf1+ 23. Rg1 Rxg1# or 23...Nxg3#; 20. Bd3 Rxd3! (20...Bxd3 is also powerful as it threatens the same tactical idea as in the main line, 21...Bf1) 21. Nd2/Bd2 Rxd2! ]
<20...Bf1! 21. Qxf1>
[21. Rg1 Bxg1 (Black threatens mate on g2 and h2); 21. Rf2 Nxg3+ 22. Kg1 Qg2#; 21. Re2 Bxe2 ; 22. Rd2 Rxd2 23. Nxd2/Bxd2 (23. Qxd2 Nxg3#; 23. Qxf1 Qxf1#) 23...Qg2#
<21...Nxg3+ 22. Rxg3 Qxf1+ 23. Rg1 Qxg1#>
|Mar-29-12|| ||scormus: Let this be a lesson to me, not to be in a hurry to try the POTD. Very nice finish, W is already lost after Rhd8|
|Mar-29-12|| ||LoveThatJoker: I'm glad to see that Peter Biyiasas actually became a GM: Peter Biyiasas.|
It's not like I'm "old enough to remember" or anything like that, but I had read somewhere that he was only an IM. Again, it's cool to see he became a GM.
Furthermore, I'm glad that I solved today's puzzle correctly and I'm impressed by GM Peter Biyiasas' excellent tactical vision in this game!
|Mar-29-12|| ||WinKing: The black position is so overwhelming. Just a matter of finding the right combination of moves.|
20.Qe1 <(the back rank must be protected)>
20...Bf1! <(threatens ...Qxg2# or ...Bxg2# - took me a good 20 min. to find this move)>
21.Re2 <(if 21.Qxf1 Nxg3+ 22.Rxg3 Qxf1+ 23.Rg1 Qxg1#)>
22.Nd2 <(preventing ...Bxf3# & blocking access to the back rank by black's rooks - if 22.Qxe2 Nxg3#)>
23.Bd1 <(preventing ...Bxf3#)>
I found this puzzle a bit difficult for a Thursday & it ook me way too long. I think chessgames is punishing us for complaining they were too easy. ;) Well let's see how I screwed this one up. Bound to have missed something.
|Mar-29-12|| ||WinKing: Well I forgot to include the 20.Qxc4 line the easiest one of them all. That is the first one I looked at too.
19...Bc4 20.Qxc4 Rd1+ 21.Bxd1 Rxd1+ 22.Qf1 Rxf1+ & mate next move.|
|Mar-29-12|| ||newzild: THURSDAY: 2.05 - 2.15
Equal material. Black has a dominating attack. First candidate must be the knight sac.
20. Rxg3 Bc5
Of course not 21. Qxc5 Rd1+. I've just noticed that White is also threatening White's queen with his Rg3. Let's try a different move order.
Not 20. Qxc5 Rd1+ 21. Bxd1 Rxd1+ with mate to follow.
This sneaky move looks strong, because 21. Qxf1 Nxg3+ 22. Rxg3 Qxf1+ 23. Rg1 Qxg1# and other moves appear to lose at least the exchange.
Time to check.
