Problem 1995
life and death
Dragons, Fun, Giant

White has to kill all of the large black dragon (from D7 to Q18), only getting half isn't enough. You can safely assume that, because of the large eye, black will win all capturing races. Black also has sufficient local ko threats (even at the end) to be alive in ko.

White has no need to play out the squeeze at the top starting with white N17 so it isn't included in any variations. Also no variations are included where white plays H18 and black can retake at H17 (it'll be obvious what I mean when you get to the relevant part of the problem).

Play thickly - Don't give black extra forcing moves, stay connected where possible, make eye shape.
Spoil black's eye-shape (duh!).
Keep an eye on your liberties.
