1.a3…. Opening is called the anderssen opening. This is a variation popularized by the player Anderssen and had played several games using this opening against Paul Morphy. These kinds of openings can be used in amateur chess on the board match as a surprise to the opponents.
Polish gambit is a variation which arises from a polish opening but with a3 as the first move. This opening favours those who want activity for a pawn sacrificed by white. The second move results in a variation for white, if black wants to prevent white’s b4 advance if he wants to place the knight on c6 then he goes ahead with the move a5 preventing b4 but white gambits a pawn with the move b4 anyway. Polish Gambit has not occurred much in top level chess.
Creepy crawly formation
Creepy crawly formation follows the move order 1.a3 e5 2.h3 d5. The majority of the results at a high level has resulted favoring black as black plays at the center with white getting a lot of weakness created. Now in this opening in order to prevent the bishop from creating the pressure along the b2 h8 diagonal black plays e5,then white moves h3 eyeing the g2-b7 diagonal for the attack. Black proceeds to play at the center with d5. Below is the game
1.h3 d5 2.a3 e5 3.g3 g6 4.Bg2 Bg7 5.d3 Ne7 6.e3 0-0 7.Ne2 Nbc6 8.Nd2 Be6 9.b3 Qd7 10.Bb2 Rad8
A standard setup where white fianchettoes both the bishops, white plays defensive waiting for black to commit a mistake. 11.Kf1 f5 12.Kg1 g5 13.Kh2 Ng6 14.Rb1 f4
A best way forward for black to capitalize on the weak square f4. 15.exf4 gxf4 16.b4 a6 17.Re1 Qf7 18.Nf3 fxg3+ 19.fxg3 e4 20.Ng5 Qe7 21.Nxe6 Qxe6 22.Bxg7 Kxg7 23.Qc1 Rf2 24.Qe3 Rdf8 25.dxe4 Qe5 26.Rbd1 Nh4
Black now wins the bishop on g2 and there is no way forward without loosing the bishop.
The move order for it is 1.a3 g6 2.g4.Here white wants to dominate in either the kingside or the queen side rather than playing the game in the centre which happens in most of the standard openings
1.a3 g6 2.g4
The initial position of the andersspike opening… Bg7 3.Bg2 d5 4.h3 c5 5.d3 Nc6 6.Nc3 e6 7.Bf4 e5 8.Bd2 Nge7 9.e4 d4 10.Nce2 f6 11.b4
Trying to break at the strong support present at the centre.
Qd6 12.Qb1 b6 13.f4 Be6 14.Nf3 0-0 15.f5 Bf7 16.b5 Na5 17.fxg6 hxg6 18.h4 f5 19.gxf5 gxf5 20.Ng5
The beginning of an attack on the black king with the knight eyeing towards the black king
f4 21.Bf3 Bf6 22.Nxf7 Kxf7 23.Qa2+ Kg7 24.Kf2 Kh8 25.Rag1 Bg7 26.Rg4 Bh6 27.Ng1 Rf6 28.Nh3 Qe6 29.Qb1 Raf8 30.Ng5 Qd7 31.a4 Nb7 32.Rgg1 Nd6 33.Bg4 Qb7 34.Nf3 Nf7 35.Rg2 Rg8 36.Qa2 Qc7 37.Rhg1 Nd8 38.Kf1 Rg7 39.Be1 Rf8 40.h5 Qd6
The passer present on the h5 square has a lot of role in helping white attack the black king via the g6 square. 41.Bh4 Rfg8 42.Qc4 Rf8 43.Bxe7 Qxe7 44.Qd5 Re8 45.Bf5 Rg3 46.Rxg3 fxg3 47.Rxg3 Bf4 48.Rg4 Qf7 49.Nh4 Qxd5
This move enables white to proceed on the offense and gain a piece in the next few moves
50.Ng6+ Kg7 51.Nxf4+ Kh6 52.Nxd5 Rf8 53.Rg6+ Kxh5 54.Nf6+ Kh4 55.Rg4+ Kh3 56.Rg8+
Now white wins a whole rook and then the game
The polish gambit is a game that has not occurred much at the top level chess but if used might sometimes be a shocker for your opponent which might sometimes be a psychological advantage for the player ready to create such an attack.
The creepy crawly formation defense by white might be the better defense against an inexperienced chess player whose activity is always at the center and does not depend on the pawn storm for creating an attack on the king but this defense if played is one such which should be watched out for.
In the Anderspike opening, the king usually is not castled on the kingside and may also remain at the center having more stable center for white. It is a rather comfortable attack which can be undertaken for a no-castling chess variant rather than a standard chess as the downsides stated has to be carefully considered for the player.
