no i agree with you hazz. its not a call against everyone. but you saying its a snap fold isnt right either. if you fold this vs regs you are the one giving up equity because regs are shoving ATC here.
OP didnt say villain was a reg, but he does have regish stats (assuming those are unfiltered), so if villain has a clue he is shoving ATC here and we can call.
of course if the SB is capable of folding even 1 hand here then we have to tighten up. but folding nash calls against players who have a clue about SB ICM not only loses you money, but loses you future equity because our opponents will fail to adjust (assuming we never call him light). yes its light, but it can be a call.
Especially if OP plays with villain a lot then SNAP call this, to gain more walks in the future.
i also understand that nash is always a little off because it assumes everyone is playing nash and that rarely happens (unless you table select very badly). but making a close call here against some villains is fine imo.
i think the 'snap fold' isnt really telling the whole story.
