;B[qo]TR[qk]MA[qo]C[Good opening, 1 stone on star point, 1 knight's move enclosure in adjacent corner. There is an opening called the "low Chinese" which incorporates a fuseki like this minus the X marked stone, plus the triangle move. If you are interested in learning openings, look at this page on Sensei's library: https://senseis.xmp.net/?header=keywords&term=Opening.  See variation.]
(;W[pj]C[And here your opponent occupies a move close to where your stone would have been had you played the opening I just mentioned.  Splitting your corners apart with this stone on the star point is simple but effective.]
;B[jq]TR[pj]MA[qo]MA[jq]MA[pq]C[This is usually called a "wing", a stone on a middle side star point extending from a corner enclosure.  If the triangle marked stone were black, you would have what is known as a "double wing". Very strong formation.]
;W[mq]C[Again, your opponent seeks to split you apart.]
;B[mo]MA[np]MA[fq]C[This move is a bit high in my opinion, it's a 5th line move while you are still only 9 moves into the game, you might want to play lower maybe on one of the x marked points.  F3 is good because it approaches the bottom left corner and makes a loose base for your stone at K3.  In the opening, a good rule of thumb is: play the third and fouth lines.]

If the white marked group were absent, you could have a better chance at running the square stone into your group above (also marked with x's).]
