This has been a spot iv'e been running into a lot recently that I'm not sure how to handle.

I've been calling a lot wider from the BB with marginal hands because leakbust said it would be more profitable, and I have a general question about that. since I only have to pay 2BB to win 5BB (assumming I'm calling a standard pfr) how much equity does my range of hands have to have against a pfr in order to make the call profitable. if we were both considered all in pre then it would only have to be > 40% but since position comes into play and of course the potential to win big pots with suited connectors and suited aces should i only play hands that are >= 50% vs his range? 60%?

A lot of the time I will flop tpgk, tpbk on a flop like this. my standard play is to check raise if they have a cbet > 66% or bet into them if the don't cbet very often to protect my hand. Is that okay? I remember on one of my other hand posting someone said never to check/raise because theres no meta game at 4NL.

snap call the shove against this random half stack.

against this type of stack it doesn't matter how you really play it as long as you're shoveling your money in asap. leading is fine if you expect him to check a lot.

I like donking here, yay, when we raise we face a much narrower range than we face when we get a call, + easier forppl to spaz or raise us when we donk, look more fish, yay donk here is good i suspect

if you gona x/raise i think folding is bad.

i agree with donkbet, dem daimonds dont hurt too much either
