Side Pawn Picker (2)

Diag.1

In Diag.1, you need to remember the sequence from ▲P-87. If the rook pulls back to 82 or 85, △R-24 would be valid in this case as there is not the attack from △N-45. The threat is the pawn drop on 23 to take the bishop.
Thus, against ▲P*87, △R*76 is a common move. After that, continuing with ▲R-84 △P*82 ▲P*23 △Gx ▲P*24 (Diag.2), gote seems to get into trouble already.

Diag.2

However, gote here has a counter attack with △N-45 (Diag.3)

Diag.3

In case of taking a gold with ▲Px23+, △Bx88+ would be a more severe move for sente, and in case of ▲B-77 or ▲K-68, the gold could run to 33. Therefore, sente has no choice but to play ▲G-77. After it proceeds with △Bx ▲Bx △G-22 （Diag.4), there are still a lot of variations, despite bishop-gold exchange.

Diag.4

I show the some variations which were actually played in pro games.

(1)▲K-68 △R-26 ▲S-38 △K-62 ▲P-46 △G*69 ▲Kx △Nx57= (Diag.5)

Diag.5
Gote is slightly better

Gote is slightly better at Diag.5 because the rook on 26 can invade in the opponent's camp.
△G*69 is a tactical move. △Rx46 instead is not good with ▲P-23+ △Gx ▲Bx11+, and △R-28+ is not also good with ▲Px45.

(2)▲K-68 △R-26 ▲B*15 △Rx29+ ▲R-23+ △K-62 ▲+Px22 △Nx57+ (Diag.6)

Diag.6
Gote is much better

▲B*15 is not really a good move, although the pawn can promote and take the gold, because at Diag.6, gote can not take the promoted knight. If taken with the king, the king-bishop fork with △N*65 will occur. If the king run to 78, gote would be much better with such as △G*76, △N*75.


(3)▲S-68 △K-62 ▲P-23+ △Gx ▲B*56 △Rx ▲Px △N-57+ ▲Sx △B*75 ▲B-66 △Bx84 ▲Bx △R*79 (Diag.7)

Diag.7
Gote is better

Although ▲B*56 is a tactical move aiming for taking the knight and at the same time, preventing the rook from turning into 26, the attack from △Rx56 is a good sequence as sente's camp has a weak point against a rook drop. At Diag.6, gote has an advantage. This is just one of the variations though.

When gote plays △N-33, the knowledge of the variations around here may be important. I think gote tends to be better against ▲P*87 relatively.
