for what it's worth (i suck at NL), i think this is a bad call.

you got ATs. at best, you're against 2 unders, in which case you're 2:1 to win. under pair, you're coin flip. overpair, you're like 1:7 or something brutal like that. dominated, you're like 1:5.

best case scenario is 2:1, and you're willing to gamble your entire stack? shouldn't even matter who the player is!
