I proposed T3, but this doesn't work because of white-T2, which takes away the eye at T1 . I thought black could get eyes at S3 and T2 but white prevents this with T5. This threatens T4, but black can't play T4 because white could then capture with S3. Not having learned my lesson, I now believe in black-T2. This makes an eye at T1 and defends the stone at S4 through the sequence, white S3, bT4, wT3, bS2 (takes). This leaves eyes at T1 and (T3 or S3). If white plays T4 black answers with S3, forming shared eyes at T1 and S2. Lew Mammel, Jr. ihnp4!ihuxr!lew
