Conditions for double bishop sacrifice

Is it possible, as it is with the so called 'Greek gift', sacrifice on h7 or h2, (the knight in range of g5 square, the queen must reach of h5 square or diagonal b1-h7, lack of knight on f6, etc ) to recognise the elements which constitute a successful double bishop sacrifice?

Thanks in advance Robbie.

As far as I am concerned the only condition required for a double bishop sacrifice is to have two bishops! After my game had finished in our final club league match last night I watched the final ten minutes of the board one clash. The following interesting position was on the board with white to play.



Shredding the nerves of the watching players our man, thought impossibly long before playing...

Hi Raggers.

I'd say Robbie was right (it happens once a year) 🙂
A double Bishop sacrifice conjurs up thoughts of Bishop sacs on h7 and g7
to expose the Black King.

If it needs to be catergorised then it most likely fits under a
'pawn promotion combination.' (Albeit a faulty one.)

But yes, this is right place for it and what a glorious post.
I've been squealing for the past 40 years that league chess hides
some fantastic games and moments but they are on the whole ignored
or relegated to the small print in Chess Magazines.

Instead we get stuffed with games from players and places we cannot
prounounce and all to often it's 15-20 moves of theory and an excuse for losing.

The net to a certain extent has helped to share these moments (thank you Raggers.)

Here:


Can White play 1.Qb1 and after 1....Qxb1 2.Qxe7+


It has a perpetualish look about it. Or Maybe not.
Black will have to do some cute wriggling to get out.

Of course I doubt if that was the intention after saccing the two Bishdogs
to sac a Queen for a perpetual. 🙂 (if indeed there is one.)

A good moment shared.

Hi Robbie,

You pretty much have it.

The two bishops aimed at unprotected g7 and h7 pawns
Queen gives check on the h file
Queen drives the king to the h file
And a rook lift that can successfully slide over to the h file with check

Here's an example from Rasmusson - Pulkkinen 1933

From this position, white sets up the double bishop sac

Hi Robbie,

I thought the most famous double bishop sac was Lasker v Bauer Amsterdam 1889 which is so well known it even has a wikipedia article on it. All the elements kneecaps has itemised are present. Sorry I don't have a pgn version to hand that I can post this evening.

Hi GP,

Hi Raggers.

Yup, that's a simple win. I was clutching at straws.
A few sleepless nights for the Black player till the next game.
Did the match hinge on that result.?

Hi Robbie.

The seeds appear to be, two Bishops aiming at a naked castled King.
(Naked as in no Knight on f6/f3) The Queen must be able to reach the
h-file with a check and a Rook(s) lift in the position.

Here is one from the Black side.

Kirilov - Furman, Russian Ch. 1949

Wow, thanks Raggers and CP and GP, these are amazing, really amazing.
