;W[ei]C[This is a bad move for white no matter the board size. ]
;B[kf]MA[cc]MA[dc]MA[cd]MA[dd]MA[cj]MA[dj]MA[jj]MA[kj]MA[ck]MA[dk]MA[jk]MA[kk]C[This, in theory is a good move, but right now, its far far too small. Look at the rest of the board... there are still technically 3 other corners that have no stones in them at all. Because of wites play on E5, that corner is totally wide open.

The marked positions are other and better places you could have played.  ]
;W[ff]
;B[hc]C[Same problem... Though white has two stones that are doing nothing... they are still doing more than the three moves you have played thus far. You have focused on just one corner so far, and you need to spread your stones out so that they are doing more on the board. ]

;B[cd]MA[dj]MA[ck]MA[cl]C[great move... but... there are more urgent things on the board. UIrgent in the Game of Go is a move that needs to be played, it could be to guarentee life, or it could be that if you dont play there, then white will, making it also a valuable move. 

In this case, your stones on the bottom left of the board, the ones marked, are in danger of being killed. ]

;B[dh]C[This move does nothing at all. Not only can white still get the two eyes, but he is connected to all of his other stones, so basically all you did here was give white a point, and give him sente, which means that you game him the chance to take control of the game. ]
;W[ee]
;B[ec]
;W[fc]MA[eb]MA[dc]C[count your liberties. This stone f yours only has two liberties, and isnt connected to those four other black stones. 

If it only has 2 liberties left, then that means it can be put in to atari at the next given oppertunity. ]
;B[bd]
;W[dc]MA[bd]C[White puts your stone in to Atari, meaning that it only has one liberty left, and means that it can be killed if you dont do anything about it. 

But, the issue here is more complex, he is also invading and reducing the size of your corner that you rightfully stole. That marked move of yours has done nothing but let white in the door to steal what you already stole from him. ]
