I think this is a definite raise on the flop. I wouldn't assume any cbet into 3 players is weak. I also rarely assume someone is going to barrel/bluff a lot at the micros which makes calling worse. There are also a bunch of action killing turns so I'd just raise now. UTG has 94.5 bbs which isn't that short.
As played I'd make a smallish value bet.
misread HH - ambtndplyr is right, flop raise is def best. the earlier we inflate the pot the better.
OP: to illustrate this, if you think about the different betsizes and diff lines we could take;
a) raise flop:
flop: (pot .82) + .41 + 1.40 (raise)
turn: (pot 2.63) + 2.1 (our bet) + 2.1 (his call)
riv: (pot 6.83) which his a really good price to call with Qx /overpairs
b) flat flop
flop: (pot .82) + .41 + .41
turn: (pot 1.64) + 1.1 (our bet) + 1.1 (his call)
riv: (pot 3.84) which allows us to only bet like $3ish
Just remember, the main leak of micro stakes players is that they are going to call too much - best way to exploit this is valuebet as much as possible. That means valuebet big and valuebet thin (hence river bet, not that its really that thin). Dont fall into the trap of betting small with monsters cause ur afraid they'll fold. Just vbet wherever possible.
Yeah raise flop for sure. This is 4nl where I would expect people to not be in the habit of folding a lot of good made hands or strong draws. The only reason to flat would be if you expect him to either barrel very often or make some tight folds. Neither of these is probably true.
Openraiser's cbet is weak here, so I don't think he has Jx or an overpair. His range is going to be very air heavy so raising I think is going to be less +EV than calling....unless we have a note/read of course on UTG's betting pattern.
It doesn't matter if his range is very air heavy here (which I don't think it is) unless we expect him to be barreling his air a decent amount (which I wouldn't expect from a 39/7).
