Now that was one absolutely beautiful combination..! Capa ROCKS!

yea he sacrifices and plays like a pro

 *****the idea of 7.Re1 is more than just winning a pawn, it is the beginning of a well known trap that all players should take into account when playing the Ruy Lopez Steinitz Defence

  This move forces black to play 7...e:d4, opening the center. Otherwise if 7...0-0 then after white plays the combination 8.B:c6 B:c6 9.d:e5 d:e5 10.Q:d8 Ra:d8 11.N:e5 B:e4 recapturing the pawn 12.N:e4 N:e4 13.Nd3! f5 most logical resource for saving the Night 14.f3 Bc5+ 15.N:c5 N:c5 16.Bg5! then if the Rook on d8 move anywhere for example ...Rd7 then white has the double threat on the Rook on f8 and the Night on c5 after 17.Be7.  At best black is left with a Rook+Night versus Rook+Rook endgame wich should leave white with very promising results.

   An alternative variation to this trap that should be taken into account happens after 10...Rf:d8.  If this should ocurr then white should play along similar lines 11.N:e5 B:e4 12.N:e4 N:e4 13.Nd3! f5 14.f3 Bc5+ but now 15.N:c5 fails to gain any advantage because the Rook has been moved from f8 so white has look for other resources than the double threat after 17.Be7.   White should play 15.Kf1! threatening both the Night on e4 and the Bishop on c5.  Blacks best resource to fend off the threat is the interesting move 15...Rf8. Now white must play 16.Ke2, though blocking the Rooks file with your king may look akward it secures the double threat on the Night on e4 and the Bishop on c5.  If white instead follows through with 16.f:e4? black has the powerful discovered check f:e4+ allowing black to eventually recover from being a whole piece down.  If white play accurately at best black can escape a piece down in this variation.
