Na5. Hi Stuart, I think the main reason Na5 is bad involves search ... it is not that Black gives up a center pawn, since without a deep search programs will think Black can get the White e4 center pawn in return with 1... Na5 2.Nxe5 Nxb3 3.axb3 Nxe4. The reason 3...Nxe4 does not work is because Black's king is uncastled, on the now opening e-file. So if you want to fix this without search, add a bigger penalty for poor development when the king is uncastled. Black is using an extra tempo to exchange knight for bishop, and that is the most relevant reason why (without search) it should be avoided. Robin
