Recently I found out the gambit introduced in last week’s blog actually has a name. It’s known as the Kunin Double Gambit. It comes from the opening moves; 1.d4 d5 2.e4 e6 3.Nc3 Bb4 4.Bd2 dxe4 5.Qg4, daring Black to take the second pawn with 5…Qxd4.
Because the name is a mouthful, and I’m not entirely sure to pronounce it, we’ll just call it KDD.
Last week we covered the very active line 5.Qg4 Qxd4 6.Nf3, leading to all types of chaos and confusion.
I promised we would look over the more popular 6.O-O-O. So, here we go …
The move 6.O-O-O leads to some pluses in White’s game. His king is safer from check, his rook has a nice d-file to attack the enemy queen and his bishop is ready to move to e3, g5, or even take on c3 should Black play …Bxc3. Meanwhile White’s queen is hitting the kingside pawns and keeping an eye on the center.
Black can certainly castle, but that is a passive plan. Black’s kingside pawns are normally used to harass the white queen move away from the center and develop his queenside pieces. For the moment at least Black’s king is going to stay on e8.
That doesn’t mean he is entirely safe on e8.
White usually stands better in the KDD if Black fails to push his kingside pawns.

If Black protects his rook with 10…Ng6, then 11.Nf6+ Ke7 12.Nd5+ again wins the queen. Finally, If the knight is taken, then White has 11.Qxh8+ Ng8 12.Qxg8+, which is good enough for a win.) 1-0

Black can try 6…f5. And White can try 7.Bh5!?.
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.Bd2 dxe4 5.Qg4 Qxd4 6.O-O-O f5 7.Bg5!?
7…Qe5? [Not 7…Qxd1+, hoping for 8.Nxd1? fxg4, but 8.Qxd1! wins. But after 7…Qxf2 (forced), Black is doing OK.] 8.Rd8+ Kf7 9.Nf3
9…Qa5?! (Not 9…fxg4? 10.Nxe5!#. But 9…exf3 10.Qxb4 is probably OK for Black.) 10.Bb5! (White is now threatening 11.Be8+ Kf8 12.Bg6#.) 10…Nc6?? (Necessary is 10…g6.) 11.Ne5+ Nxe5 12.Be8+ Kf8 13.Bg6mate 1-0
Instead, White has 7.Qg3!, increasing pressure on Black’s kingside pawns and protecting his own kingside pawns.

(An obvious and interesting move.) 14.Qxe3 Nxe3 15.fxe6 Nxd1 16.e7!] 13…Nf2 14.Rg1 fxe4 15.Nxe4 Nd3+ 16.Rxd3 Rxf4 17.Nxc5 Nc6 18.Re3 Nb4 19.a3 Nd5 20.Re4 Rxe4 21.Nxe4 b6 22.Bc4 Bb7 23.Neg5 b5 24.Bxb5 Nf4 25.Nxe6 +- 1-0 (25…Nxe6, then 26.Bc4 Bc8 27.Re1 Kf7 28.Ng5+)
Finally, Black can play 6…h5. This pawn push is protected by the rook and Black, at least for the moment, doesn’t have an additional weakness on the kingside.
Here, Black has a decent chance.
