I agree – the guidelines are completely different for heads-up. When that's the case, I typically play "all-in or fold" as long as my cards add up to 17 or so. I've only been playing for a year or so, though, so I'm not sure if this is the best strategy or not. I'm sure stack size should play a factor.

I signed up for the Steem Poker League... haven't actually played in any games yet but hopefully that changes soon.
