J4s is a reasonable call, J4o is not (although 43o/54o/64o can be calls). Over the next orbit you need 2 shoves to assure yourself of at least a heartbeat.
This is a frustration call. Wait for SB/LP to find a better holding. Win and you get the BB back anyway. Same with BB+SB if you fold SB.
And with blind sizes, you can ~martingale into very healthy position rather quick.
Rather than general tendencies, I want to know how btn has been playing at this ft. He should be jamming pretty wide here though you are behind his range. Ideally you'd prefer to flip against sb though.
