Sac Or No Sac?

“A sacrifice is best refuted by accepting it”
Wilhelm Steinitz

Tactics decide the game. If you want a simple comparison, tactics are like putting the ball in the net. You need to know what to do when the opportunity is staring you in the face. Do you know what to do? Have you practice enough to firstly recognize it and secondly to take advantage of it? Let’s see how good you are in the following position. The question is: should white sac on h7 or not?

Analyse the position and firstly go with your gut instinct. Gut instinct is most of the times right and it relies heavily on personal experience. Personal experience is based both on the aspects of the game you learned and on direct feedback you got while playing your games. Have you ever looked at this sacrifice from a theoretical point of view? How about playing it or having it played on you? If you did, most certainly your gut instinct gave you the right signal and you got it right. If you did not, it is very likely you got this wrong.

It could be helful to look at position 4 under “Tactics” in my previous article HERE and added below for convenience:

It shows a successful sacrifice on h7. Now what you should do next is compare the two, identifying what aspects in position 4 made the sacrifice successful. Do you also find them in the proposed position 4.1 above? Let’s have a look at them together:

  • The pawns defending the castle have not moved
  • Kg8 is the only defender of the h7-pawn
  • Black does not control nor attack the g5-square and allowing 2. Nf3-g5
  • Qd1 could join the attack via the d1-h5 diagonal


  • White has the e5-pawn (position 4), while the pawn is missing in position 4.1
  • Bd2 controls the c1-h6 diagonal (position 4), while it is blocked for the moment by Nd2 in position 4.1
  • Re1 could come in and help the attack using the 3rd rank (Re1-e3-h3), while Rf1 would require an extra move to do that in position 4.1
  • Bb7 is trapped for the moment by Nc6, while Bc8 has an open c8-h3 diagonal

Now it is time to weigh the above points and formulate a conclusion. Lesson 15 (level 5) of our chess app covers this nicely and if you have gone through it, you will notice rather quickly which one of the 6 needed conditions for the sacrifice to work is not met. That is condition #2:
“#2. The h2/ h7-pawn is defended only by the King and cannot be defended by any other piece in a move”
Kg8 being the only defender of the h7-pawn is met but black can simply defend the h7-square in a move. The sacrifice does not work:

Well, knowing these details makes the difference between winning a game in spectacular fashion and looking like a fool. It is obvious in what category we all want to be, so study these tactics and practice them; your efforts will be rewarded. Hope you liked it and will consider studying tactics closely, possibly using our app.

About Valer Eugen Demian

The player - my first serious chess tournament was back in 1974, a little bit late for today's standards. Over the years I have had the opportunity to play all forms of chess from OTB to postal, email and server chess. The journey as a player brought me a lot of experience and a few titles along the way: FIDE CM (2012), ICCF IM (2001) and one ICCF SIM norm (2004). The instructor - my career as a chess teacher and coach started in 1994 and continues strong. I have been awarded the FIDE Instructor title (2007) for my work and have been blessed with great students reaching the highest levels (CYCC, NAYCCC, Pan-Am, WYCC). I am very proud of them! See my website for more information. I have developed my own chess curriculum on 6 levels based on my overall chess knowledge and hands-on experience. A glimpse of it can be seen in my first chess app: I can help you learn chess the proper way if this is what you seek!
