I know this pattern..black has only a few seconds left on the clock!

@awardchess : you're right - D.Pruess and Dan Heisman were referring to 'tactical' patterns, rather than 'strategical' patterns. If you include those, the # is estimated in the tens of thousands.

edit : and you have 'endgame' patterns as well

2,000 patterns aren't enough to become a strong chess player! 

Ne4 was actually much simpler than I thought.

Best defense I could find for black:

That's for Ahmed's last example.

I'd say after Rd1 and Qe7 then Ng6 pushing Qe8 then Qxg5 Rg7. Ne7+ Qxe7. Rd1+ Qxd1. Qxd1+ and white should have an easy game.

I think this way is possible too:

@Elubas
Man I didnot mean any thing .. but I played against Fritz and

so get on it from this situation and explained my moves so

ask the engine why it played like that :))
Also , Dr Ghost played against engine and get on it by

another way also ask the engine why he lost ,,,
But what I mean that here we are having 2 ways have succeeded

into win on engines not more ,, Also I admit that it was one

of the best and the most difficult problems I have ever seen ^^
but the more you try the more solutions you can get !
Good buzzle , Nice commentators ! Thank you for your positive

comment ! (but me and my friend has the pride that we found

solutions and all of you  (nice players & strong ones as I think) just analyze them ! sorry but it is

the truth :) I like you !

Cataphract887 -- the OP's comment wasn't powerful enough to make it easy for me 

It's really lovely -- Ne4, threatening the pinned bishop, and after ...fxe4, Rf6!!. The point is to mechanically block the key diagonal for the queen, and taking on f6 with the rook doesn't change the issue after exf6. I think the tactic works because it creates a replaceable outpost on f6, and this, combined with the trapping and isolation of the pinned bishop, will mean two really strong attackers to decimate the open king. At first I was looking at lines like Ne4 fxe4 Rxf8+? for a long time, desperately trying to get it to work, but it took me a long time for me to see Rf6. It's a short line, but I would imagine it being extremely difficult to find something like this in a game -- opportunities like this are only up for a very limited time.

Ahmed -- Why so stubborn? "Two solutions," really? With that said, your suggestion of 5...Qg8 in the first variation posted by dr.ghost is a good try, but I think that white should keep his huge f6 pawn defended in response: 6 Qh6. I was trying to get 6 Qh5+ Kxf6 7 Rf1+ to lead to a quick mate but that's not so clear; it makes the most sense to keep the f6 pawn, then attack later. White's threat is very simple -- Bh7, when the queen has to leave at least one sensitive square, and black has trouble defending because his position is so cramped. Trying to escape with 6...Ke8 could be met by 7 Bg6+ followed by f7.

If we know how to participate in international tournments I think we woud be GM at 14 years old and now we could br super GM

@ Dr-Ghost
 Man I don't know why we arenot rated ? ... In this position and by the isolated pawn in E5 how could white loose ? white will win ... Ok Mr hicetnunc here we are 2 egyptians giving you 2 solutions congratulations every body ;)

Rh6 mate attack not stopable:)

@Dr-Ghost


no no no .. Why 4...Rh7 ????
I think here white loose ^^ cause 4.Qh5 e4xd3 (free piece and threaten promotion and you have not check )

@Ahmed_AboAisha it will be mate

@Dr,ghost ..
2...rf7 ;)
If check I can threaten your queen and still have advantage try it ..
why not?
also...
5...Qg8 ^__^ why not ??
------------------------------
I think it is  a good variation but waiting the solution of the toic owner ^^
don't hurry saying it is the best

it is the best choice :)

is that a pattern for mate ?? i  could  take black queen ;enough ?

Ne4. It was easy because the OP said it need an idea from a different world, good hint(that means look for an impossible move;the more illogical the better). 

Ne4 with Rf6....

Man I don't want to frustrate any of you but I come to equlization I think unrated egyptian man did it !! (I will participate in international tournment next summer ^^)

Man it hurt my brain :( 

Look to this variation and explaination of my moves :) I played against engine more than 13 times to do it but it is finished
