  Pulo y Gata: A fine win by Yuffa. How young is he?

White's black squares control was just too much, Bologan is barely recognizable here.

Dec-22-15  siggemannen: Apparently not that young, he's 18.

  Phony Benoni: Kind of hard to go wrong on whose move it is today!
Feb-16-18  Walter Glattke: 30.-Qxd6 31.Rxg7+ Kxg7 32.Bxh6+ Kg8 33.Qg6+ Kh8 34.Qg7# or 32.-Kh8 33.Bxf8+ Kg8 34.Bxd6 so 30.-Qd4.
Feb-16-18  Cibator: Bologan was always likely to lose one way or D Yuffa.
Feb-16-18  goodevans: <Walter¬†Glattke> Against 30...Qxd6 white has simply 31.Qxh6+ Kg8 32.Qxg7#.
Feb-16-18  yadasampati: <<Phony Benoni> Kind of hard to go wrong on whose move it is today!> Hahaha, indeed. In that sense we had a very easy one today :-)

  Richard Taylor: My solution was as played but I played:

30. f4 Qd4 31. Qxh6+ Kg8 32. Qxe6+ Kh8 then

33. h5 which is winning by nearly 10 points versus

33. Qe5, which gets only 5 points more or less.

However White is clearly winning and the move played was probably a better move in the sense that it removes the potentially dangerous Black Q.

  Richard Taylor: <Phony Benoni: Kind of hard to go wrong on whose move it is today!>

I looked at it for a while not noticing White was in check. Once I found it well, it is reasonbaly easy to find f4 when i thought maybe Qxb2 and Bf1 to follow but White can overcome that idea...

Feb-16-18  patzer2: In tackling today's Friday (30. ?) puzzle, I figured 30. f4 was the only logical way to get out of check.

My follow-up after 30...Qd4 was 31. Bxh6 +- (+7.01 @ 36 ply, Stockfish 8). It's not as strong as the game continuation 31. Qxh6+! (+63.31 @ 36 ply, Stockfish 8), but I'm content with it for a quick solution to a moderately difficult problem.

P.S.: Black's decisive mistake was 27...Rxc7?, allowing 28. Rxc7 +- (+10.58 @ 30 ply, Stockfish 8). Necessary instead was 27...Bd7 28. Rxb7 Qxb7 +- (+0.85 @ 32 ply, Stockfish 8).

Early in the game, our Opening Explorer indicates Black has scored better with the popular 6...ba6 = (0.00 @ 32 ply, Stockfish 8) than with the rarely played 6...Nf6 7. e5 ⩲ (0.47 @ 31 ply, Stockfish 8)

Feb-16-18  Pchief: After 30.f4, what's better is 30...Qd4 than 30...Qxb2? At least the latter creates some counter play concerning b-pawn's promotion
Feb-16-18  Lambda: What an odd puzzle. White is in check, so you get out of check in the most obviously sensible way. No further calculations necessary to justify the move, it leaves the king best protected, and it hits the queen.

  agb2002: White is two pawns down.

The black queen is giving check.

The natural move is 30.f4:

A) 30... Qxd6 31.Qxh6 Kg8 32.Q(R)xg7#.

B) 30... Qxb2 (White must take into account Bf1 and b2) 31.Qxh6+ Kg8 32.Qxe6+

B.1) 32... Kh8 33.Bh6

B.1.a) 33... gxh6 34.Qxh6+ Kg8 35.Qh7#.

B.1.b) 33... Bf1 34.Bxg7+ (34.Qxd5 Qxg2+ -34... Qf2 35.Bxg7+ and mate in two- 35.Qxg2 Bxg2 36.Kxg2 Rb8 37.d7 b2 38.d8=Q+ Rxd8 39.Rb7 also seems to win) 34... Qxg7 35.Rxg7 Kxg7 36.h5

B.1.b.i) 36... b2 37.Qg6+ Kh8 38.h6 Rg8 39.Qf6+ Kh7 40.d7 b1=Q (40... Rg6 41.Qxb2 Rxh6+ 42.Kg1 with the double threat d8=Q and Kxf1) 41.d8=Q wins (41... Rxd8 42.Qg7#).

B.1.b.ii) 36... Rf6 37.Qe7+ Rf7 38.h6+ Kg6 (38... Kg8 39.Qe8+ Rf8 40.Qg6+ Kh8 41.Qg7#) 39.Qg5+ Kh7 40.d7 Rxd7 41.Qxf5+ Kxh6 42.Qxd7 b2 43.Qb7 wins.

B.1.c) 33... Rg8 34.d7

B.1.c.i) 34... Bf1 35.Bxg7+ wins (35... Rxg7 36.Qh6+ and mate in two; 35... Qxg7 36.Rxg7 Kxg7 37.Qxg8+ Kxg8 38.d8=Q+, etc.).

B.1.c.ii) 34... Bxd7 35.Rxd7 with the threat Qg6-Bxg7+ looks winning.

B.2) 32... Kh7 33.Qh6+ Kg8 34.Qg6 with many threats (h5-h6, Be7, d7) seems to win.

C) 30... Qd4 31.Qxh6+ as above.

Feb-16-18  saturn2: <Malt Gone for
30.f4 Be8 31.Q:h6>

I think in your line 31 QxBe8 just wins a piece
Feb-16-18  malt: <Saturn2> Yes, Well spotted that man 31.Q:e8 Q:d6 32.Qe7
Feb-16-18  trnbg: way too easy for Friday.
Feb-16-18  njchess: A bit easy for a Friday, but I will take it. 35. f4 ♕d4 (Black's queen is pinned to that diagonal, or else mate follows) 36. ♕xh6+ ♔g8 ▢ 37. ♕e6+ ♔h8 38. ♕e5 Δ mate in one ♕xe5 39. fxe5 +-

  Breunor: Strange puzzle; Friday puzzles are usually out of my league, I may get one in 5 or 10; but here the first few moves are all forced.

30 f4 is obvious to even beginners; Qd4 or Qxb2 are the only moves that don't give white either a won queen (with mate imminent) or mate in two.

Then again 31 Qxh6ch or Bxh6 both are winning; I went for 31 Qxh6ch Kg8 32 Qxe6ch Kh8, again this is pretty easy to spot.

I then went for 33 d7; according to Stockfish this is something like +13; but here pretty much every move wins.

I do think the text 33 Qe5 is very good, even though it has a lower Stockfish score than other moves here, the idea of eliminating queens in a won position is a great lesson for beginners and powerful GM's alike.

Feb-16-18  gofer: Hmmm, we are in check, so there are very few first moves to look at. But there is only one defence that is really forcing for white (as it attacks the checking piece). So I will ignore the rest, but the issue I have is that the main line I have found just wins pawns, so its not a "slam dunk" - which makes me think I have missed something!

<30 f4 ...>

White threatens Qxh6+ and then Qxg7#, so the white queen must be attacked OR the black queen must stay on the a1-h8 diagonal.

30 ... Be8 (Be2 is worse)
31 Qxh6+ Kg8
32 fxe5 Bxh5
33 Be7 +-

Black must give up a piece to stop the pawn.

30 ... Qxb2
31 Qxh6+ Kg8
32 Qxe6+ Kh8/Kh7
33 Qxd5 +-

Black's position is in tatters and white's d6 pawn is going to win a piece before black b3 pawn can threaten promotion!

~~~

Okay, pretty simple really...

Feb-16-18  BOSTER: Maybe 33.Bh6 is the best.

  Breunor: Move 33, according to Stockfish:

d7, 13.86
Qe5, 5.37
Bh6, 9.28
Qe7, 7.37

Everything wins.
