This seems to happen with some regularity at the 180s. Opp is a major winning regular, according to Sharkscope he has played 84k tournaments, most at this level and the $15s. I'm guessing this isn't AA or KK, so do you call here?

2 folds, Hero raises to 60, 2 folds, CO raises to 1,490 and is all-in, Hero ???

just fold. seems like a strange move by a winning reg.

call randoms, fold regs

Yeah just give it up and make a note.

I have notes on some regs doing this with kk+, so wouldn't rule it out completely. Though more likely to be qq,jj,ak in my experience.
