Dsachs asked:

I had a question about a tactic in the lines of Pirc where white plays Bc4. For example, 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bc4 Bg7.

In this setup Black has the chance to play ...Nxe4 when Nxe4 ...d5 forks e4 and c4 and regains the piece. I know White is able to win the pawn back with Bxf7+, but I’ve also noticed my opponents very rarely find this line. So I’d like you the phrase your response in a parallel dimension of chess where this isn’t possible, if you’re willing to do so.

Basically, I’m not sure how important being able to win this pawn should be to Black’s goals. Lately I’ve been ignoring …Nxe4 in favor of castling and improving Black’s position for a few moves. My reason for doing so is to avoid wasting opening tempi just for a pawn. Is this crazy? 

Dear Mr. Dsachs:

I have no way of knowing if you (or I, for that matter) are or are not crazy, demented, schizophrenic, bi-polar, or simply whacked out of your mind. However, I’d bet that even in a parallel dimension not taking a free pawn when it’s given to you is karmic folly since you are purposely spitting on a gift from the gods for reasons that defy understanding. Have no doubt that these elder gods WILL get back at you for this affront – do you really want to make an enemy of Kali?

But, let’s leave your parallel dimension and return to the asylum planet that we actually reside on. Though madness is the norm here, even the most cracked individual will snort up a pawn if it’s freely offered (I prefer to smash it into powder first, but the pawn will fit if you breathe in very, very hard). Thus after 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bc4, 4…Nxe4 would be the only intelligent move IF it actually won a pawn. But … it doesn’t. First off, 4...Nxe4 5.Nxe4 d5 6.Bd3 regains the pawn, while 4…Nxe4 5.Bxf7+ Kxf7 6.Nxe4 also creates material parity. In fact, it’s the latter line that has chased most players away from 4…Nxe4 since, though Black has two Bishops and more center pawns, his iffy King position and the potential weakness of e7 and e6 appears to be in white’s favor.

So, allow me to implore you to take free pawns if they are really free (or only cost a few cents). I should add that you not winning the e4-pawn just because your opponents can’t find the two “I’m easily getting my pawn back” variations is disturbing. You shouldn’t make decisions based on the hope that people won’t see the obvious, but rather make your decisions on the truth of the situation.

Now let’s jig our way to the value of 4.Bc4. This system, with the addition of 4…Bg7 5.Qe2, used to be very popular and very dangerous, but now it’s not thought to be that big a deal. Here’s a quick taste of its theory: 

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bc4 Bg7 5.Qe2 Nc6!

The discovery of this move stopped the bleeding that often occurred from other lines:

5…c6 6.e5 Nd5 7.Bd2 0-0 8.0-0-0 Be6 9.Nf3 Nxc3 10.Bxc3 Bxc4 11.Qxc4 b5 12.Qe2 Qb6 13.Kb1 b4 14.Bd2 c5 15.dxc5 dxc5 16.h4 Nc6 17.h5 Rad8 18.hxg6 hxg6 19.Rde1 Nd4 20.Nxd4 Rxd4 21.Bh6 Bxh6 22.Rxh6 Kg7 23.Reh1 Rg8 24.Qf3 f5 25.exf6+ exf6 26.Rh7+ Kf8 27.Rb7 Qe6 28.Rxa7 Re4 29.Rd1 Qf5 30.Rd8+ Re8 31.Rxe8+, 1-0, Silman - M.Sullivan, San Francisco 1977.

6.e5

Sharp, scary, but perhaps not best. James Vigus makes a case for 6.Nf3 Bg4 7.Bb5 in his excellent book, The Pirc in Black and White (Everyman Chess, 2007).

6…Nxd4 7.exf6 Nxe2 8.fxg7 Rg8 9.Ngxe2 was thought to be just good for White since three minor pieces can often run rings around a Queen. However, there’s been some argument about this assessment over the years, though I personally would rather play with the three minor pieces.

7.Bb5!

7.e6 was given several trials in its day, but was found wanting after 7…Nxd4 8.Qxg4 Nxc2+.

Ripping open the position for black’s Bishops.

Though Kveinys won this game, it’s not clear if White really achieved a significant advantage in the opening.
