Tesuji and Reading

After stupid mistakes in my games, In-seong tells me to solve easy tesuji problems. I work through these books:

一眼の手筋, Cho Chikun 2003
強くなる手筋, Nihon-Kiin 2002
強くなる手筋 (Go Super Book #16), Fujisawa Hosai 1971

Exemplary Reading Mistake

The following is an example of a reading mistake that might be exemplary.

Black to play and capture the two stones separating black’s three groups.

Taken from 強くなる手筋 Super Book #16), p. 85.

Black 1 is the first move I consider.

I dismiss this move, because after 1 and 3 white is able to connect to the stones on the left side.

I switch to 1 and read the sequence to 5, which captures white in a net. I read on and am satisfied that the net holds.

However, I completely miss the fact that both the white stones and the marked black stones have three liberties and that white is going to win the capturing race.

What I missed in the first step, was the move at 1.

Ways to learn from this:

Read this problem again, including mistake and solution.
Consider the liberties of the stones involved.
Look up problems with similar suji.
