  C[Initiating contact is not generally Black's best strategy. With 9 stones of handicap, Black is holding a gun at a distance and White is a karate champion. You really don't want to get up close. If White gets close to you first, you have time to work out safer defenses. X is simpler.]

  C[Does White have a plan or not? When Black cuts he will be making more territory and reducing the scale of sacrifice of his side stone. And White may well have to lose sente to defend.

Probably better for White to defend the other cut. If Black then plays circle, white can drive a line toward the center and then switch to capping Black's side handicap. White should threaten to enclose as soon as possible at 9 stones.]

  LB[le:X][oc:Y]

  C[No. Better to try X to see how Black responds. Besides, Black is alive most likely. So better to take sente elsewhere and have Black waste another move living because Black won't know he is alive. The problem for White is finding a way to play where Black could be set up to die. White needs to play X to create an invadable corner and block connection.]

  TR[jq]
  C[No. Black thinks to take territory here, but it can still be invaded. Better to play X (which we already know Black isn't). Since Black is sacrificing his stones, X is good because removes Black's weak point at 1. Y is good as it helps secure profit while threatening to revive the sacrifice.  Z also threatens to recover the sacrifice, but there is no profit in it so it should not be played now. As for protecting against invasion, triangle is the choice. This prevents White from invading and moving around.]

But SHOULD WHITE? Why not pretty please try out the X invasion first before deciding it's over.  Oh, well. White kept invading the smallest places first.

Black was clever in deciding to sacrifice triangle. Y was another key move. And White helped his own loss by forcing the 1-7 exchange earlier. Without that sequence, White still had a chance. And if White had tried X, White might (or might not) have seen something useful happen. 

Better luck next time, White. Your general dominos attack was good.]
