The Bxa6 sacrifice

Did you like my game? And did you spot the similarity between queenside and kingside?

Please share your thoughts,since im just a 1000 rated player.

WHy would you play 17. exd6? and not 17. e6 crushing?

Open file for rooks... Was i wrong?

well e6 is a passed pawn and a attack

i'm surprised he played 12...Bg6 instead of taking en passant - that keeps his Bishop on the attack and gets rid of a doubled pawn.

yeah i played g4, then saw en passant then became happy because he overlooked it

4.d5 is a good move but than after playing that good move you followed up with bad moves.

After you played d5 you must understand the center is locked(Center Pawns can not move) which means play will begin on the wings either left wing or right wing. In this line white usually plays on the Left wing becuase his d5 pawn is so far advance. An black plays on the right wing. becuase of his e5 pawn so far advanced.

You play on the side your pawns point. So his are pointing king side yours is pointing queen side.

5.Bc4 is a bad move.

6.Nc3 is a bad move as well.

The reason why 5.Bc4 and 6.Nc3 are bad moves is becuase of what I mentioned above. Play begins on the wing. So you need pawns to pawn storm on that wing.

Your bishop and knight are blocking your C pawn from moving. An your bishop and knight are not doing anything (They are not active in those spots).

Your bishop on c4 is hitting his own d5 pawn. Its not active its useless there.

Your knight on c3 is doing defense which is good. However, you need your pawn in front of the knight.

5.c4 would of been a fantastic move to play as white in this position. You gain space you than develop the pieces behind the pawns. Your pawns act like the battering rams to tear stuff down.

Your Light Square Bishop would of been better on e2 or g2.

In this line specifically it usual gets developed to e2. It breaks any pins black might do. Also it has got a nice active spot. Bishops are long distance pieces so on e2 it can attack all the way to a6 and if you move the knight on f3 it can attack some light squares on f3, g4, h5  etc.

After the move 5.c4 for you I would than play 6.Nc3 or 6.Be2  etc.

The move order can change. It just depends on what black does after you play 5.c4.  If black plays 5...Nf6 he will be hitting your e4 pawn so than you would have to play 6.Nc3 defending the e4 pawn.

However, the difference is your C pawn would be on c4 and your knight would be behind your pawn on c3.

If black played another move lets say 5...a6 or something stupid like that. You have several options.

6.Be2, 6.b4, or 6.Nc3 again.  These are likes the spots you want to go to naturally for your pieces.

You have to think of piece activity. Where is the most active spot for you pieces.

Your light square bishop would like e2 attacking both left side of board and right side of the board.

Your dark square bishop would like e3 attacking both sides as you can see very active.

You want your knight on c3 behind your c4 pawn.

You will want to castle

You will want to play b4 etc. just doing a huge pawn storm on the queen side.

These are general idea's and themes in this position which are very great. Simple and easy to understand.

4.d5 might be a good move, but is it the best? dxe5 is likely to force a Queen exchange and kill your opponent's chances to castle, and leave white with "simple development" towards what is likely to be a quick, straightforward win.

Also, those locked centres are rather tedious .

... or, if you like the Ruy Lopez, what about 4.Bb5?

P.S. Note that by move 4. this Philidor has actually transposed into the second most common variation of the "Scotch opening".

16 exf5 wins

4.dxe5 and d5 are both equally considered good in this position. I rememeber checking this line with an engine a while back. Both lines were considered like top choices.

I think some engines prefer d5 slighty more though gaining space.

This position can turn into a few different positions. If the move d5 is played. The position usually will turn into like a KID type of position.

Almost like the Classical Mainline KID.

17.Bxa6 bxa6 18.Qxa6+ Kb8 19.Nb5 c6 20.dxc6 winning

Incorrect! why would you help black out? e5 was !!! 

But exd6 was bad.

exf5 wins a bishop in move 15

exf5 is a very simple win. How did you miss it?
