I think V1 has 77-TT, perhaps some FD however his hand is capped here and fairly face up so I think he folds to any further action. V2 can have anything here from gutshots, FD and air. I dont have A in my hand to there is quite a lot of flush draws there. My thinking is I am ahead of those, have some equity vs 1P hands and have decent folding equity with about $500 of dead money from V1.

Was my all in reasonable or did I just spew my stack?

Preflop is fine

Flop, I am not sure between check and bet/call, but bet/shove is definitely the worst option. Opponent is getting 4:1 and doesn't sound like the player type to fold an overpair.

I prefer bet small/call. You can get away with betting like 220 here. You aren't expecting many pairs to fold on the flop, so a small bet folds out equity from hands like qj, jt, as well as leaving lots of room behind for turns and rivers that will overwhelmingly favor you. And you can easily call a raise because you beat bluffs, which it sounds like V2 can have, and there are many good turns for you (a/k obviously, 4/5 give you additional outs while also being very unlikely to help V, any diamond gives you a fd)

On the other side, suppose you are facing a $220 cbet as V2 and you hold a hand like 99. Raising isn't good because you risk your whole stack when Hero has a premium pair. But obviously folding is out of the question, you usually have the best hand. So you call and hate life on most runouts.

If you're facing a $550 cbet on the other hand, jamming is profitable. There is $1100 in the pot already, you are ahead most of the time and H is almost getting the right price to call off with two overcards. Even if you never get called by worse and always get called by better, if H's range is {AQ+ JJ+} shoving is about break even. In practice, H will make some mistakes (calling too often, folding too often, maybe his range is wider) and turn a profit for you.

$300 isn't nearly that large but I see how V2's raise ends up committing your stack. I don't know if that's necessarily good or bad. Sizing is funny and something I'm still struggling with.

I think I check give up flop with V1 flatting pre bc he just has 99-QQ always and thats not folding flop. That plus station whale guy means you have like zero fold equity otf.

It really sucks and I hate check/give up a low paired board but like every time I bluff them I get called 2 streets at least (and think to myself how come I never have aces here)

It's also not always a give up, if V1 checks and whale bets I'm always calling and likely calling down.

As played cbet smaller.

As as played, I don't think it's horrible if whale's range really is that wide and V1 can never show up with KK/AA. Id be mighty tempted to tilt rip it im here. I like your moxie.

But yea prolly spew

so you tried to bluff a fish that plays most hands after he put in half his stack??? total spew.

poker is a game of people.

Probably raising pre to about $250

yeah, it is spew, but I like it. I don't think it is long term profitable, but in this one hand, I think you played it correctly.

you are most have some decent equity against V2, as he has something like a 2, gutter, or weak flush draw. I think your read on V1 was correct. He most likely had a middle pair, which you correctly used to spew by V2 to be able to rep a big pair, and almost take down the whole pot without a showdown.
