Hey, I've been following a brazilian winning reg (NL100) on twitch and he has a very wide cold call range on the button vs UTG and MP. I've seen him flatting A2s-A5s, 76s, 9Ts, basically lots of suited hands. Is that standard? My cold call range from the BU vs these positions looks more like all suited broadways, A9s+ and 77+. Am I being too tight?
