[[ 5.Be7 ]] and [[ 5.Bc5 ]] are both played Bc5 carries more superficial attacking potential along the g1 a7 diagonal but Black s natural plan of playing .d6 will cut this bishop off from the defence of the kingside plus it means White s natural plan of c3 followed by d4 will come with gain of tempo. Be7 is the most common move for these reasons. The bishop is not necessarily a bad piece on e7 where it supports the knight against any coming Bg5 ideas and in the long term if Black is forced into playing .g6 to evict a White knight from f5 it s useful to have the bishop available to redeploy to g7 via f8. [[ 5.b5 ]] plans to develop the c8 bishop on b7 and the f8 bishop on c5 where they both aim at the kingside along adjacent diagonals. The difference between this move and the immediate .Bc5 is that on .Bc5 White can play c3 and get the bishop back to c2 in one move here she must lose a tempo going via b3. Hence .b5 is more common than .Bc5. [[ 5.Nxe4 ]] gives the a game a different flavour. Black tries to distract White from her development by snatching a pawn leading to a more open position. As usual when a player grabs a pawn in the Ruy Lopez trying to hold on to it turns out to be a bad idea. =Common Moves= Col begin uto loatright Col 3 Chess diagram rd bd qd kd rd pd pd pd bd pd pd pd pd nd nd pd bl pl nl pl pl pl pl pl pl pl rl nl bl ql rl kl 5.Be7 (Closed variation) Col 3 Chess diagram rd bd qd kd bd rd pd pd pd pd pd pd nd nd pd pd bl pl nl pl pl pl pl pl pl pl rl nl bl ql rl kl 5.b5 (Columbus variation) Col 3 Chess diagram rd bd qd kd bd rd pd pd pd pd pd pd pd nd pd bl nd nl pl pl pl pl pl pl pl rl ...
