An opening which has been fascinating me for a while is the Schliemann defense played in the Ruy Lopez or Spanish opening. Playing directly for the initiative with this aggressive opening by opening the f-file and attacking the kingside. It can also be used as a surprise weapon against your unknowing opponent! The opening goes as following:
After this, white has a numerous options like 4.exf5, 4.d3 or maybe 4.d4!? but developing with 4.Nc3 is considered best, as it develops a piece and supports the e4 pawn.
Below a wonderful game played by Pillsbury against Tarrasch:
I would like to conclude this article with my own game where I was playing with the black pieces:
I'd just like to point out that in the Tarrasch game, there was threefold repetition starting on move 49.
That game featured a clever recipe by Livi (13.a4 Bb4!?), but this is not enough. Instead of Nekhaev's 14.c3?! and the great piece sac 14...Nc5! white could (and should) trade Queens with 14.Qc4! Qc5 (forced) 15.Qxc5 Nxc5 16.Ke2, or 16.Nc3, when it is very hard to show compensation for a two-pawn deficit.
Yes, that's the engine's first choice. But 13...Bb4! wasn't some casual punt in a blitz game. This was high-level correspondence, where both players obviously considered 14 Qc4 for White. In fact Nisipeanu had prepared the whole thing to play against Carlsen. After 14...Qc5 15 Qxc5 Bxc5 and then, for instance, 16 Ke2 c6 17 Nc3 Ne6 18 Nxe4 Rhe8, Black actually has compensation for three pawns, as Junior Tay shows in his recent book. Apparently, Nisipeanu was more worried about 14 0-0 Qc5+ 15 Rf2 Qxc2 16 d4, though that's defensible as well (my one draw came in this line).
