Kings are among the least powerful pieces, but, at the same time most valuable. If, you loose your most powerful piece your Queen, you can still play on. Loose your king and the game ends.

Rooks are next in value to the Queen. They are each worth five points.

Knights are equal with Bishops - three point each. If, you take a bishop with knight and loose him in the next move, it is afair exchange.

Bishops are worth less thanQueens and Rooks but more than pawns - they are worth three points. One Bishop isworth three pawns.

Queens are strongest pieces on the board. They are worth nine points each. With every move you make watch carefully to see that you do not leave your Queen open to capture

Pawns are worth one point each, but, should not be undervalued. Do not sacrifice them without seeing some gain ahead.
