I need help with an enigma. It perplexes and vexes me.
The puzzle is as follows:

Set up the board as it was 2 moves ago.
Board: Black king A8, white king c8, white bishop g1, white pawn h2

Hints: Black must have captured a piece last move
White must of used a discovered check
Can anyone help? I am at my knees!

You have not started any games on RHP, but nonetheless, if this is an active game of yours, there should be no comment.

Still a non-starter so it must be a puzzle.

White bishop on g1, not black. Like this:



And I presume the OP means two plys, i.e. two half-moves, or one move for each player; otherwise the puzzle is unsolvable.

Black captured a piece last move, so the move before the last one it must have been white's move...

but that's a rediculous move black would have made before white took the queen with the horse...why would black leave the queen in corner like that?? Seems dumb.

perhaps the white queen was there, threatening to take the black queen next move, or perhaps this is just a puzzle

This is a retrograde analysis problem, not a chess game with white competing against black. Retros aren't concerned with whether moves are good or bad, but only their legality.
