Albert Yen's next commentary here is from his 6th round win against New Zealand's Xie Kai Kun.  Albert gives us another peek at how games can develop from his favorite pincer opening.  For the game moves, Albert also includes LeelaZero's (AI) winrates.

Note:  LeelaZero's winrate percentage above is the winning estimation for the player who just moved.  The parenthesized percentage is how much the winning estimation increased (or decreased) as a result of the given move.  The playout count (in this case 1000) indicates the number of Monte Carlo runs in the game tree search - very roughly speaking, the more playouts the better the estimation.

Be warned that the winrates in this game may not be completely accurate, because WAGC uses Japanese rules, which has a 6.5 point komi rather than LeelaZero's 7.5 point komi.  In a normal game this would barely make a difference, but because the margin of lead in this game is very small throughout one point can make a big impact.  In other words, Black's position is always better than what the winrate indicates.];

In this position Xie chooses a different move than my previous opponents.  I think the push here is premature.  If Black wants to play the pincer at A there is no need to make these exchanges now.  I was very happy that Black pushed here this early.];

The push naturally strengthens White's position in the corner and White is happy to make territory on the fourth line (marked areas).]

Since Black already made the exchange at A, it is actually better for Black to commit and push twice more here.  The move in the game allows White the large turn at B in the future.]

Leela doesn't like this reinforcement to seal the corner, but for humans this is an obvious big point.  The AI instead suggests playing at A.

I really don't like White's shape after Black invades at R17 so I chose to defend here, aware that the AI would probably not like this move.];

Cutting at B does not work here for Black, because Black's marked stones only have 3 liberties.]

I played this kakari thinking that Black will likely respond at A, which leaves a large point for me at B.  However, the proper move would be to defend at C to address the aji that the O17 stone has.

This move allows Black to attack first at D or E (though Black didn't take advantage of my mistake in the game).];

Quick count of territory:

Black has 17 on the right side, 14 on the top, 12 on the bottom left, 2 on the left side, plus 8 points on the top left and 3 points for prisoners (Black has a net sum of 3 more prisoners than White).  Black's total is 47 points.

White is easily 30 points ahead on the board.

White 1 with Black 2 is largely neutral.  However, White gains a lot with the exchange of 3 and 4 because White gets an extra stone on the outside.  Black 4 is essentially a useless piece inside his own territory. 

The only difference between this variation and the game is that White made a throw-in, so Black has an extra stone at A, but that makes no difference (both in terms of points and thickness).]

We can do a quick positional judgement here.  White has roughly 16 points on the bottom right plus 9 points on the left side and at least 10 points in the center, assuming White makes a move around A (Total: 35 points).

Black has about 17 points on the right side plus 6 points on the top right, 5 points on the top, and 7 points on the top left (Total: 35 points).  Black has some potential in the bottom left corner but that is far inferior to White's potential in the bottom and left sides (Let alone the terrible aji at B).]
