This is David vs Martin in the first league. I was just curious why David chose i18 instead of j21. I guess they both make a connection to the bottom, but it's just that personally I find j21 more straight forward. I was wondering if there is some reason I'm not seeing?

It looks like h20 is already connected to e17, so no need to strengthen that area…

i18 makes sure that h20 is connected with e17, j21 doesn't.

Beware enemy pegs adjacent to your gaps! 29.J21* 30.H19* cuts my H20-E17 connection.

This is why Martin played 28.G21* instead of G23**. He was trying to make a double threat.

For example 29.G18** 30.L21 would have slowed me down a bit.

29.i18* covers both threats more directly.

Oops I overlooked that black H19* cuts both H20-G18 and H20-F19 on the way to E17.

Twixt is a pretty interesting game!
