1 - How is it posible 4 Bishops with all Black Pawns in their original squares?

2 - How did Black King go to a1 with the wall of White Pawns?

I was wondering how the black king got out from behind the wall of black pawns.

1-white's bishops on the dark squares cannot go from c1, so both are promoted
2-white has four bishops, of which at least three are promoted. White still has all eight pawns. White's pawns have never been able to travel through the seventh rank, which is still intact with all black pawns.
3-at least five black pieces have been captured by white's knights on the eighth rank
4-black's last move was Kb1-a1 or Kb1xa1. In both cases this is not the best move: there is no mate in two after Kb1-c1

And bishops they hoped over to

Good , just keep that in mind

I’m confused, is this chess or checkers?
