Making calls without good odds
(regardless of whether you know better or not) and overplaying TPTK, that is being terrible at poker.
To be honest, I do similar, I play about twice as many hands as I should, don't fold them easy enough post-flop and keep lowering the SPR in spots so I can make a marginal shove which is usually close to neutral EV at best and given the nature of playing in questionable spots I make enough mistakes that those questionable plays are overall -EV.
So yeah, I suck at poker too.
You cant call a pre flop raise with suited connectors then hit the flop four to the flush and fold.
You don't play SCers so that you can call an all in, you play them so that you can push all in (well, bet/raise, whether it's all in or not). There's a big difference.
