analysis

atulab: I'll try to present my way of thinking about problems which I call "wishful playing" (you'll understand why in a moment) Here, just crawling on the edge doesn't work, so we have to find a tesuji (this is obvious: we're working on a problem after all)

So, we can find 2 weak points in black position: -his escape route to the center is very weak: a stone at a threatens this directly -b looks very interesting because if black connects at c, white can cut at a: too bad connecting at d isn't obviously wrong

so now, on with my attempt:

attempt n°1, part 1

atulab: and look like the obvious (naive ?) way of connecting : white attacks the weak point in order to give black a clumsy shape. (I'm not sure this is appropriate: I feel like this exchange destroys ko threats) after , black must make a decision: should he connect to resist ? of play the ko ?

case A: black connects
continued

atulab: black can't get away ! hurray !

case B: ko

atulab: black has to chose between 3 moves: -the a points don't work: the cutting stones will get captured when white plays b -this leaves : white now has 2 local ko threats Can we call this result satisfactory for white ? I'm not sure ...

local ko threats

atulab: and are the ko threats I mentionned
