Title: Previous Two Moves?
Post by THUDandBLUNDER on Sep 8^th, 2003, 6:47am

1) What was White's previous move?

2) What was Black's previous move?

White has just played [hide]Nb4-a2+[/hide], because otherwise [hide]Black would have moved into check, which is not a legal move[/hide].

Before that, Black [hide]can't have moved his King, so there was another piece on the board, which was captured by White's last move. It must have moved to a2, so it can't have been a Pawn or a Knight. A Rook or Queen would have come from the first rank - impossible (White in check). This leaves Bb1-a2 as Black's last move, which changes White's answer to Nb4xa2+[/hide].

Excellent answer.

Irresistible nitpick: [hide]Black bishop could have also captured a White piece on a2. [/hide] :P
