A hypothetical... best way to proceed.

[Zophar]

A big debate has been going on about how this hand was played, or could've been played better, by the SB. I've posted the 1st part of the hand. Really the primary debate was whether a call or raise by the SB would have been the best play. Further info regarding playing styles, tendencies, etc. weren't available yet.(I realize that it is very low stakes, however there is a learning process for everyone. I had nothing to do with the hand except for follow up discussion).
