chessgid=370482&move=1.5&moves=e3The Van 't Kruijs Opening (also Van 't Kruys) is achess opening defined by the move:1. It is named after theAmsterdam playerMaarten van 't Kruijs (1813 –1885 ) who won the sixth Dutch championship in1878 . As this opening move is rarely played, it is considered an irregular opening, and thus it is classified under the A00 code in theEncyclopaedia of Chess Openings (ECO).The opening 1. e3 is not popular according to
ChessBase ; it ranks eleventh in popularity out of the twenty possible first moves. It releases the king's bishop, and makes a modest claim of the centre, but the move is somewhat passive. The queen's bishop's development is somewhat hindered by the pawn on e3, and White usually wants to take more than a modest stake of the centre.Although not very aggressive for a first move, play may transpose to lines of the
English Opening (c2-c4),Queen's Pawn Game (d2-d4), or reversedFrench Defence (delayed d2-d4) or reversedDutch Defence (f2-f4) positions.The Van 't Kruijs Opening is not a common choice for Grandmasters, but its ability to transpose into many different openings explains its attraction for some people such as the Czech Grandmaster
