May-16-14  Pedro Fernandez: CG put this puzzle as difficult, really? I see the total variation in less than two minutes. On the contrary, in the anterior puzzle I didn't see 29...Qc8!! Indeed our mind is really complex!

  Jimfromprovidence: <Morf> <But thats the problem I've been running into for White since after either 27.Qh5 or 27.Qf6, Black has 27...Be6 and with <f7> protected and the back rank clear, Black has avoided immediate disaster>.

After 27...Be6 white can still play 28 Rh3.

Now he has two ways to force mate and black can only protect one of them.

May-16-14  Pedro Fernandez: 24.Bg6 is extraordinarily simple and logic. After this move the tree of variations are relatively simple too.
May-16-14  Rookiepawn: <Jimfromprovidence> from your position

29. ... Kxg7
30. Qxh7+ Kf8

Didn't the BK find a hole to escape?

May-16-14  Rookiepawn: Sorry, move numbers are wrong, take one back:

28. ... Kxg7
29. Qxh7+ etc.

I think is a rat chase but don't see a definitive line... Sorry, though if I surely miss something.

May-16-14  Rookiepawn: 28. ... Kxg7
29. Qg5+ Kf8
30. Rxh7 e5!?


May-16-14  Rookiepawn: 28. ... Kxg7
29. Qh6+ Kg8
30. Rg3+ followed by mate in g7

Forget about my brilliant lines please. Sorry.

May-16-14  Sally Simpson: Hi perfidious, Chess Dad and Once.

The convoy can only go as fast as it's slowest ship.

You must write(post) for your weakest reader. There are a lot of lads here that cannot hold a position in their mind.

A diagram assists a great deal and makes it 100% clearer what you are showing and saying.

(a picture is worth a thousand words...or so they say.)

A well placed diagram can save a couple of dozens of words.

If you click on the sqare 'b8' you will get the fen from any part of the actual game.

Grabbing the position after move 10...

click for larger view

...took 12 seconds.

OK you have to tamper with it a wee bit if you want to show an unplayed variation. Some of you obviously put in a lot work showing cute line and variations. Adding a diagram will aid the post and in some cases trigger questions about another line because everyone can plainly see what you are showing.

To me it does seem a waste of time posting something that others cannot follow. At least give it a try....Please.

  Once: A convoy? Well, maybe. That's one way of looking at it. I prefer the Indian proverb:

"Chess is a sea in which a gnat may drink or an elephant may bathe."

Or mosquitoes bathing and elephants drowning. And a few other combinations of insectoid grooming and elephant aquatic antics.

My guess is that a grandmaster would look at the comments and probably gravitate towards the ones with lots of variations. That's an elephant bathing. A beginner would probably like lots and lots of diagrams. Insects drinking, because if they drink enough one day they might pack their trunks and turn into Dumbo.

And there is a sliding scale between those two extremes - elephants and insects. I've always been partial to otters myself. Cute ears. If I ever get reincarnated as an animal I'd like to be an otter.

For my money, I am enormously grateful to everyone who posts here whether they include diagrams or not. I would not want anyone to be turned away because there was an expectation of diagrams. Not everyone wants to include them ... or has the capability to include them on something like a mobile phone or tablet.

Might I humbly suggest that if diagramless posts don't interest you then you always have the option of not reading them. But in a spirit of friendship and tolerance, I'd rather we didn't start laying down expectations of what people have to include in their posts.

May-17-14  Shams: <Once> Do Indian gnats drink salt water?
Premium Chessgames Member
  LIFE Master AJ: I agree with <Once.> Any posting - that sticks to the games alone - and gives thoughts, variations, etc, ... must be good. (The more, the better!)

People used to say the same thing to me, that I posted too many variations and should use diagrams. To be honestly embarrassed, it took a really long time before I finally figured out how to do a diagram ... (but I had help from a fellow poster).

Occasionally I use diagrams, and sometimes I do not ... it all depends on how I feel.

May-17-14  Rookiepawn: Hey, I didn't know the "click on b8" trick. I was wondering how kibitzers here took the time to make the fen diagrams manually.

Thx <Sally Simpson>, now I can show faulty lines crystal clear!

Feb-13-15  FairyPromotion: GOTD: Sicilian Mahia
Apr-28-15  greenfield67: How did "Sicilian Mahia" not get a run as the pun?
Premium Chessgames Member
  al wazir: 22...Qxd3 would have saved black.
Premium Chessgames Member
  offramp: <al wazir: 22...Qxd3 would have saved black.> I wouldn't have played it. It looks awful. I might not even have thought of it.

I really liked this comment:
<stingray0104: wow- at one point or another Mahia offers each one of his pieces up as a sacrifice (though some sacrifices are "deeper" than others) except his queen. But then again, he offers "a" queen on move 27 so that's close enough. Played like a madman, well done.>

Apr-28-15  Pballa: <22...Qxd3 would have saved black.> No it wouldn't. Black is toast.
Apr-28-15  5hrsolver: How about 23...Bf2
Premium Chessgames Member
  kevin86: The steamroller mate will follow by the rook.
Apr-28-15  Gambitor: 17...Bc5 seems to stop white's attack. It's a very logical move, the bishop will defend the KS.

Analysis by Stockfish 6 64:

17...Bc5 18.Kh1 Bxd4 19.Qf4 f5 20.Ne4 Bxg7 21.Rg3 Rf8

(-2.48) Depth: 35/49

Premium Chessgames Member
  Domdaniel: Ahhh. That 24.Bg6! really is a beautiful move. Would I have seen it? I hope so. Would I have seen it *in advance*? Who knows?

As so often, the point is not to find a striking move when it arises, but rather to base one's earlier play on that possibility.

As <Caissas Clown> said, quoting Spielmann: < "I'd win from those positions , too - the issue is actually =getting= to those positions".>

Premium Chessgames Member
  maxi: Evidently Mahia was on an On day.
Apr-28-15  FairyPromotion: I'm extremely glad that this game finally made it as GotD. A true pearl.

Let me also link to another poisoned pawn brilliancy that starts with the bishop sac on f6 (and there it is accepted, but the LSB is on c4,) and soon turns into a sacrificial orgy:

R Byrne vs Larry Evans, 1965

Apr-28-15  dfcx: Black might still save the game as late as 23...Bf2 24.Rf3 Qxf3 25.Bxf3 Bd4 26.Be4 Bxg7 27.Bxh7+ Kf8
