I feel like I'm going to lose this week with a triple 20

4b5 seemed blocky so I gave it a quick try and this appeared.

other:

(L) B2 L

2 bad on green but the DR ends up green, funny

I think this is my first time getting a good solution from the 'stacked on both sides' 2c4 shape lol

I didn't have any other DR so I was forced into solving this.
