Black plays bg7, so instead of playing nf7, I played bf7+ to remove castle opportunity and then took bishop back out to mid. I know I would be up more material if I wouldve forked the bishop and queen, but I was still in position to do so the next turn. Why is this an inaccuracy?
Because in the engine logic 5,3 is much better than 3,8. But that is rubbish. A winning position is a winning position. And if you found it more easy to win with Bxf7+ then it was the best move for you - and in no way it was an inaccuracy.
