The correspondence between surface structural trends and anisotropy in the upper mantle, found in many regions of the world, strongly suggest that orogenic processes involve not only the shallow crust but the entire lithosphere. The delay times between fast and slow waves reflect the relative strength and penetration at depth of the deformation field. In general it is found that the fast polarization direction is parallel to the absolute plate motion in cratonic areas, to the spreading direction near rifts or extensional zones, and to the main structural features in transpressive regimes. In this paper we describe the different possible origins of anisotropic behavior of the seismic waves and the seismological techniques used to define anisotropic bodies. All the games used in the videos are as fresh as they can be.Anisotropy is a common property of the Earth's crust and the upper mantle it is related to the strain field of the medium and therefore to geodynamics. This video course will give you an idea about the most important strategical ideas of the opening, for both White and Black, from a modern perspective. And became once again popular on a top-level. The Italian kept the complexity of the battle. For there is the danger of the Berlin desert. Both sides will get their chance.Īnd it became interesting again. After all, all the chess troops will be on board. Behind the solid pawn construction, he would patiently manoeuvre with his pieces, waiting for the right moment to come. The first player decided not to initiate pawn clashes. The came Giuoco Pianissimo, the Slow Game. Capablanca, the great Cuban proclaimed the end of the game. Logic slowly led to dry positions with mutual chances. What can be more logical than that?īut still, logic is not enough in chess. Take for example this former main line where both sides play as logically as they can:ġ.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Bd2 Bxd2+ 8.Nbxd2 d5 9.exd5 Nxd5Įvery move brings a piece into the game, and/or fights the centre. The Italian attacks got slower, more careful. Then came the first world champion who explained the importance of the fundament when attacking. The bishop on c4 was viciously eyeballing the vulnerable pawn on f7, the only pawn which lacked a piece defence from the beginning, whereas the kingside knight was ready to support it, quickly getting closer via the g5 square.īlack was not ready to defend patiently at the time and even more ambitious openings like the Traxler Counter-Gambit emerged. The aggressive development of the white pieces suited their ambitions well. People played "noble" chess, trying to sacrifice as many pieces as they can. Not, this was not the idea - the perfection was to mate it in a brilliant way, with sacrifices.
