This blog was going to feature the Dragon. But one of my correspondence games ended today (12-11-2019), and it inspired the following article.
Enjoy!
~~~~~~~~~~~~~~~~~~~~~~~
Most players know a piece is equal to three pawns. Materially, this is even. The advantage, however, is to the side that is attacking.
In a line of the Najdorf Sozin, White sacrifices a piece for those three pawns. Despite some technical problems to solve, he usually does well.
The sacrifice begins with the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 7.Bb3 b5 8.O-O Be7 9.Qf3 Bb7?! 10.Bxe6! fxe6 11.Nxe6.
This is White doing well.

1-0 (White’s threat is aimed at h6. If 22…Rh8, then 23.Qg3+ does the trick.)

Now Black does not have to take the offered bishop. He can simply decline the material. But he is still a pawn down and White has a budding attack.
This is White doing very well.
