|Jan-13-15|| ||zb2cr: With Black threatening mate by ...♕f1, White has to do something fast. Fortunately, the position has a ♕ sacrifice, more like a Monday than a Tuesday. 32. ♕g8+, ♔xg8; 33. ♗e6+. Notice the double check. Without that, Black could block the ♖ check by retreating his ♗. With the double check, the only move, of course, is 33. ... ♔h8, answered by 34. ♖g8#.|
|Jan-13-15|| ||ndg2: Black came never out of the defense with any counter play the whole game. Pretty rare sight for a Petrosian game.|
|Jan-13-15|| ||swordfish: Indeed it's surprising to see Petrosian, with his tactics and especially his legendary defensive skills, get mated in such a way.|
|Jan-13-15|| ||varishnakov: 33.Q-N8+ KxQ 34.B-K6++ K-R1 35.R-N8 mate
queen sac to expose king to deadly double check followed by mate
|Jan-13-15|| ||Penguincw: Aww! I missed 34...Kh8, but I definitely would've saw it OTB.|
|Jan-13-15|| ||KingsPawns: Qg8 is like poetry. Bravo!|
|Jan-13-15|| ||gawain: Stunning! Easy to see, sure. When you know it is a Tuesday puzzle, you first try the boldest move available. But exceptionally beautiful nevertheless.|
|Jan-13-15|| ||TheaN: Tuesday 13 January 2015 <33.?>|
Nei scalps Petrosian with a prosaic clearance involving a double check. <33.Qg8+!> lures the black king into the double check, <33....Kxg8 34.Be6++> clears the g-file white was looking for <34....Kh8 35.Rg8#> and the rook now doesn't need the queen to mate as the bishop replaced her.
The queen-lure is a common setup for a fatal doublecheck. I think what this game shows is that a rook-bishop battery, although not the strongest available, is not to be underestimated.
|Jan-13-15|| ||keypusher: <PhilFeeley> See "g." on this page for why chessgames classes 32.d7 as a knight sacrifice (and doesn't class 33.Qg8+ as a queen sacrifice).|

|Jan-13-15|| ||Chess Dad: Looks like a Queen Sac Tuesday.
33. Qg8+ Kxg8 (forced)
34. Be6++ Kh8 (forced)
|Jan-13-15|| ||patzer2: Petrosian was a great positional player and was well versed in opening theory.|
However, the maneuver 13...Bf6 and 13...Be7 to anchor the backward d-pawn and centralize the Bishop seems awkward and a bit slow.
Perhaps better here might have been 13...f5 when play might continue 13... f5 14. exf5 gxf5 15. Be2 Nb6 16. Ne4 Qxd2+ 17. Nxd2 Bd7 18. a5 Nc8 19. O-O Nf4 20. Bxf4 exf4 21. Nxf4 Bxb2 22. Rb3 Bd4+ .
Fritz 12 gives its first choice here as 13...Nb5 when play might continue 14. b3 Nd7 15. Ra2 Nf4 =.
|Jan-13-15|| ||CHESSTTCAMPS: White is down a piece, but has a dangerous passed pawn on the 7th. This distraction may have caused the very famous defender to overlook a tactical coup:|
33.Qg8+!! forces mate-in-3.
This puzzle is perfectly timed - I was very recently thinking about examples to teach children the power of the double check.
|Jan-13-15|| ||patzer2: Petrosian's 15...f5 break comes a bit too late, as Fritz indicates White is winning after 16. exf5 gxf5 17. f4 Ng5 18. fxe5 dxe5 19. g3 (+ 1.77 @ 20 depth).|
|Jan-13-15|| ||TheTamale: Whoa... I JUST BEAT PETROSIAN.|
|Jan-13-15|| ||patzer2: White's 32. d7!! is the only winning move there (32. ?) and worthy of a weekend puzzle solution. Fritz 12 @ 21 depth gives best play as 32.d7!! h5 33.Bh3 h4 34.Rg2 Nxd7 35.Bxd7 Rf8 36.Nf2 e4 37.Qg5 Kh7 38.Qxf6 Rxf6 39.Rg4 Rd6 40.Rxh4+ Kg7 41.Bc8 e3 42.Ne4 (+ 2.73).|
Perhaps Petrosian saw this and decided to let White end the game quickly with a pretty double discovered check and mate after 33...Bxd3? 34. Qg8+ Kxg8 35. Kh8 Rg8#.
|Jan-13-15|| ||Castleinthesky: A very straightforward "diversion" puzzle. The queen sac forces white's king into a double check and mate. The rest of the week is always much harder, so I am glad to take this one.|
|Jan-13-15|| ||Strelets: 33.Qg8+! Kxg8 34.Be6+ Kh8 35.Rg8# Effective demonstration of one of my favorite tactical devices by Spassky's future tennis partner: the double-discovered check.|
|Jan-13-15|| ||Longview: I did not see that one coming at all. <TheTamale> I am Petrofina.....you beat me.|
Goodness do I have a lot to learn!
|Jan-13-15|| ||BOSTER: Playing 12.Ra3,when Nc3,Be3,pawnf3 were filled the 3 rank, and then Nd3 came here, did white really see 25.Rg3 on the open "g" file?|
Maybe pieces who have <early development> have a great future.
|Jan-13-15|| ||Edeltalent: This looks like a typical case of "forgot that takeback is not automatic". I can imagine Black was already pondering over the next move after 33.Qxd3, when 33.Qg8+ was a rude awakening. Uncharacteristic for Petrosian, who was well known for an incredible sense of danger. Possibly the bishop was on g6 before (where he kept the g-file closed), so Qg8 was not a threat before.|

33. Qg8+ Kxg8
34. Be6++ Kh8
|Jan-13-15|| ||Domdaniel: "The end is Nei".
As Black is threatening mate in one, 33.Qg8+ would seem to be indicated.
|Jan-13-15|| ||tamar: Iivo Devo in action|
|Jan-13-15|| ||TheBish: I Nei vs Petrosian, 1960|
White to play (33.?) "Easy"
I remember seeing this somewhere, probably in a tactics book. Not sure if this helped me see it in under 10 seconds, or if it's just that easy! White is down a piece, and it's fair to assume that Petrosian expected recapture of the bishop on d3 to restore material equality. White's move must have struck him like a thunderbolt!
33. Qg8+! Kxg8 34. Be6+ Kh8 35. Rg8#.
The power of the double check strikes again!
