Moves 190 to 190  

B2 is a pretty simple defence. White can't W3 because after B4 there's nowhere to go. The cut at a needs 4 liberties to work and the aji in the centre is not strong enough to help. So W3 must contend with B4 instead, so B4 can cover at W3. In the game I clumsily defended at b which gave White ample room to intrude or capture.

Failure to find a working sequence
