I have always wanted to deal with this topic ... well, obviously I have ... although this was not the main thrust of the pages that I have created in the past. On this page, I discuss the "Greco Trap" (greek gift); but it is NOT the main topic, so I have always felt that the lesson of the page had gotten diluted by all the other topics and areas of discussion that has crept onto that page over the years. (Some of this was necessary ... as that page is aimed at a nearly raw beginner. So - in order to really give good instruction, many bases had to be covered.) However, on this page, I get a chance to discuss the "Greek Gift" solely ... with no other areas (of chess) or problems/lessons being dealt with. In other words, this page is as close as being a chess scientist as I can be. In other words, we are ONLY going to examine this type of sacrifice (The "Greek Gift") on this particular web-page. We are going to arrive at a critical position as quickly as possible, not even caring, (at least - for the moment); how we arrived there. The ONLY thing that we want to discuss on this page is "The Greek Gift" sacrifice. (What it is, what are its prerequisites, how it is carried out, etc.) As far as I know, this is ALWAYS a Bishop sack on h7; although one student showed me an example of a Bishop-sack on f7 that was probably highly similar in all facets of the ensuing details. Nonetheless, the true "Greek Gift" type of sacrifice normally begins with the Bishop sack on the h7-square. Now
- before we get into the actual analysis, lets look at the sample line and
discuss the main characteristics of the "average position" ... ...
...
The above is a copy of my forum on the "Chess Games" website, it outlines the basics of what the prerequisites were for this sacrifice. To all this, I would only add that a White Knight must be present to reach the g5-square ... this is normally part of the pattern as well.
rnbq1rk1/pppn1ppp/4p3/3pP3/1b1P4/2NB1N2/PPP2PPP/R1BQK2R w KQ - 0 7
White to move here, what is the correct idea here for White? 7.Bxh7+!, Like
the Greeks ... who offered the Trojans a giant wooden horse ...
White presents Black with a gift.
rnbq1rk1/pppn1ppB/4p3/3pP3/1b1P4/2N2N2/PPP2PPP/R1BQK2R b KQ - 0 7
Only
this move is correct here, as really nothing else is as decisive as this
move is. 7...Kxh7; Black - pretty much - has to play this.
rnbq1r2/pppn1ppk/4p3/3pP3/1b1P4/2N2N2/PPP2PPP/R1BQK2R w KQ - 0 8
Otherwise, White could simply retreat and be a Pawn up. (Also - the BK is badly exposed.)

8.Ng5+, '!' (Best.) This is the only correct follow-up, now the Black King will be mated, or White win material.
rnbq1r2/pppn1ppk/4p3/3pP1N1/1b1P4/2N5/PPP2PPP/R1BQK2R b KQ - 0 8
Take a few minutes and study this position as well.
[
Some students want to play: </= 8.Qd3+!?,
but after 8...g6;
8...Kg6; (Forced!?) Black must play this ... everything else is quite hopeless.
rnbq1r2/pppn1pp1/4p1k1/3pP1N1/1b1P4/2N5/PPP2PPP/R1BQK2R w KQ - 0 9
If
you are not convinced that the play of 8...Kg6; would be forced here, then
see my analysis ... ... ...
[ We can dismiss: </= 8...Kh6?; as after: 9.h4! f5; 10.Nxe6+, Black is losing his (or her) Queen. ("+/-")
{Analysis diagram.} **********************************************************************************************************
Black also loses after: RR
8...Kg8!?; 9.Qh5 Re8; ("Box?!?") 10.Qxf7+ Kh8; 11.Qh5+ Kg8; 12.Qh7+ Kf8; 13.Qh8+ Ke7; 14.Qxg7#.
{Analysis diagram.} ( ---> Analysis checked by many engines.) ]
9.h4!, (Threat / h4-h5+, winning.) Normally, Qg4 would be played in such positions, however, in this set-up, (because White has not castled); the first party has an idea that is even stronger.
rnbq1r2/pppn1pp1/4p1k1/3pP1N1/1b1P3P/2N5/PPP2PP1/R1BQK2R b KQ h3 0 9
Now Black has to work hard not to get mated from this position.
[ Even if White plays a ... "less-than-best" move here, (like
Qg4); ... ... ...
Of course, there is one doubting Thomas in every crowd, so I provide at
least one line here:
{Analysis diagram.} White has an overwhelming material advantage here. ---> Main analysis engine - Fritz 12. ]
9...Bxc3+; Now Black takes on c3 ...

11.h5+ Kh6; 12.Nxe6+ Kh7; 13.Nxd8, "+/-" (White is winning on material.)
rnbN1r2/pppn2pk/8/3pPp1P/3P4/2P5/P1P2PP1/R1BQK2R b KQ - 0 13
Black
can resign here, the second player has lost his Queen and two pawns for
only two minor pieces.

1 - 0 There are a few other pages, where I look at a combination, beginning with a sack on h7/h2, although none of these games are strictly "a Greek Gift" type of combination. However, I do think it would help the average player to study these battles ... ... ... #1.)
Its one of the grandest games of all time ... its also an original, played
by the second World Champion, himself. And it starts with BxP/h7+! #2.)
It starts with a sack on h7 ... but it does not end there, in fact;
this is only the beginning of this combination. #3.) Black also begins with a Bishop sack on h2 ... here, I am talking about: Nimzovich - Tarrasch; St. Petersburg; RUS / 1914. Once you become familiar with this pattern, you can spot its defining characteristics fairly quickly: *********************************************************************************************** A.J.

8.Be2 Bd7; 9.0-0 Nge7; 10.a4 Na5; Why did Black play 13...P-KR3 (13...h7-h6) here? To understand this move better, let's look at the (hypothetical/analysis) position that occurs after 13...0-0, see the position just below.
Now, White wins, just as in our first example, by sacrificing the Bishop on h7.

Of course, its possible to make a mistake like this deep in the middle-game, but that would be a topic for an entirely different web page! Also - if you know of any famous games that feature this type of sacrifice, be sure to e-mail me. (Please make sure that you remove the "No-SPAM_" from the e-mail address, that is in there to fool the robots/programs that cruise the Internet looking for e-mail addresses to send junk mail to.) Another example of this type of sacrifice ...
