It is a 1/2 home game and stacks are deep (300~400 BB). It is a live straddle UTG for $5.
MP1,MP2,CO (hero), BTN, SB, BB all limp. hero holds 6♠ 3♠ and is on the cut off.
UTG who had straddled raises $16 more ($21 total) and all limpers call! (it is a loose table!). hero also called since he had position and stacks were deep.
So it is 7 way to the flop. pot is (7x21=$147)
flop:Q♠ 4♠ 3♥
everybody checks to hero, hero bets $45. everyone folds except MP1 who calls. so now it is heads up. Effective stack is $420 and hero covers villain.
pot is $237, turn is 6♥
villain checks, hero bets $125, villain tanks and calls.
pot is $487, river is T♥
now villain donk shoves all in for $295.
here are my questions, I appreciate your answers:
1- what is your flop bet sizing when it is multiway (here 7 players)? do you still bet 2/3 of the pot? does bet sizing vary when it is heads up or multiway? does it stay 2/3 of the pot regardless of the number of players?
2-on the river, should I be good 295/(487+295) of time or 295/(487+295+295) of time to justify a call? which one? I am confused, what is my river pot odd?
3- should hero fold or call? I don't think villain is bluffing in this spot ever. He has seen me betting the flop and turn but still shoves all in on the river.
Thanks in advance.
