mp2 is massive whale 67/7 small sample
button is passive fish 10/5 over 200 nothing relevent noted

turn is too small, no idea what thats about. clue for the river?

I don't hate the flop but betting TPNK into 4 players is not the best. Turn fine, though maybe bet at bit more, Say 0.45-0.50.

River I like betting about $1

i forgot to mention flop. I was hoping to get the whale to myself cos he calls down with nuffin. I thought bet/fold or chk/fold over chk/call.
also what calls river that I beat?

raggy Ax hearts, KQ, QT, Maybe KJ. No point bluff catching vs passive fish

I'm curious, you guys b/f river or b/c?

For sure you can bet turn more, I don't mind betting flop if we're folding to raise, as played I like b/f river $0.95 against this guy, against aggro fish I b/c river.

bigger on the turn. 70c on the river

i'm betting at least $0.5 on the turn with the mega whale in the pot. as played on the river i go $0.75 or $0.8

I'd just mash the pot button on turn and river.

b/f 1.1
