how to castle without any problem


also look at this trap for bishop no play to win now for black
Why you use worse board. This is worst board ever

To the OP: the evaluation shows a lead for black when black plays solid: 7. Bxd7 Nxb7 8. 0-0 Be7 (you have no lead in developement (one aktive piece and castling against two developed pieces) and black has a strong center already acitvated while you lost a center pawn against a bishops pawn.... I would prefere being black here.
