Posição após o 6º movimentoRoque artificial ou Roque na mão, no enxadrismo, é uma manobra utilizada para proteger o rei utilizada quando o rei não tem mais direito ao roque normal. Por exemplo na Abertura Giuoco Piano, após os movimentos usuais:
1.e4 e5
2.Cf3 Cc6
3.Bc4 Bc5
As brancas surpreendem com o duvidoso:
4. Bxf7?!
O rei das Pretas perderá o direito ao roque porque, ou se moverá para e7 ou capturará o bispo com 4...Rxf7.
A partir de então as Pretas efetuarão uma série de movimentos para proteger rei, como por exemplo: 5...Tf1 6...Rg1
Com isso, as Brancas terão muito tempo para preparar um ataque na ala do rei, recuperar o bispo sacrificado ou até mesmo vencer o jogo.
Oh, caro!
It seems that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) spreads confusion wherever it appears.
Take the simple entry in Wikipedia, above for "artificial castling" (http://pt.wikipedia.org/wiki/Roque_artificial) – translated "a maneuver to protect the King when the King does not have the right to castle normally."
The opening used to illustrate the concept is, of course, the Jerome Gambit.
Note the conclusion of the article, "With this, White will have enough time to prepare an attack on the King, to recover the sacrificed bishop, or even to win the game."
Of course, in the diagram given in Wikipedia (reproduced accurately above) Black's King Knight has mysteriously disappeared from f6, so White is no longer a piece down.
Readers who are able to arrive at such a position "after six moves" are requested to share that information with the rest of us.



This is Blackburne's offer of a Rook (see "
Yes!
Yes, again!
9...Qxe4+
White escaped a horrible position (self-inflicted) and went on to win in perrypawnpusher - bakker, FICS rated blitz game, US, 2007: 9...Bb4+ 10.c3 Qxe4+ 11.Kf1 Qd3+ 12.Ke1 Bg4 13.Qxh7+ Kf8 14.f3 Re8+ 15.Kf2 Qe2+ 16.Kg3 Bf5 17.Bh6+ Nxh6 18.Qxh6+ Ke7 19.cxb4 Qxb2 20.Qg5+ Kd7 21.Nd2 Qxd4 22.Rhe1 Rh8 23.Qe7+ Kc6 24.Rec1+ Kb5 25.a4+ Kxb4 26.Ne4 Rh3+ 27.gxh3 Qh8 28.Nf2 g5 29.Qe1+ Kb3 30.Qe3+ Kb4 31.Qd2+ Kb3 32.Qd5+ Kb4 33.Qb5 checkmate
Not as strong as the messy 10...Qxg2 11.Qxh7+ Kf8 12.Rf1 Bb6 13.Nc3 Bf5 when White will be able to 0-0-0 his King to safety and be up the exchange and a pawn.
The position has become quite complicated, and it is hard for either White or Black to know whether to use the Queen for plunder or defense. White would have had more of an edge, according to Rybka, after 11.Qxd4 Qxg2 12.Rf1 Bh3 13.Nd2 Qg4 14.Ne4 Re8 15.f3.
Instead, 12...Bxb2 would have won the exchange; but the game is still quite complicated.
White has emerged from the battle a Rook up, and things have settled enough that he can find the win. 

Black has returned a pawn to get rid of the Bishop at b2, and now shows that he can be active, as well. The second player has the advantage, still; but White must doggedly persist.
