On a regular chessboard, there are 64 squares in total. To calculate the number of possible board combinations, we need to determine how many different ways we can place the pieces on the board.

There are six types of pieces in chess: king, queen, rook, bishop, knight, and pawn. Each player has 16 pieces at the start of the game: one king, one queen, two rooks, two knights, two bishops, and eight pawns.

To calculate the number of possible board combinations:

1. We can place any one of the 16 pawns on any one of the 64 squares. There are therefore 64 possible positions for each pawn. This gives us a total of 64^8 (or 281474976710656) possible positions for all eight pawns.

2. We can place any one of the remaining 15 pieces (excluding pawns) on any one of the remaining 63 squares. This gives us a total of 63^15 (or approximately 9.7748 x 10^26) possible positions for all remaining pieces.

3. To get the total number of possible board combinations, we need to multiply these two numbers together:

64^8 x 63^15 = approximately 2.7513 x 10^41

Therefore, there are approximately  2.7513 x 10^41 possible board combinations on a regular chessboard.

It's important to note that this calculation assumes that all pieces are on the board at once and that no rules or restrictions apply (such as not being able to put your own king in check). In reality, many positions would be illegal or unlikely to occur in an actual game due to these rules and restrictions.
