This is my first OP.
This is a 5/5 game (400-700) with an effective stack against UTG+1 of ~850. I've been sat for around 3 hours, very card dead making the odd move here and there with mixed success. In the session I have played very few hands for me. Recently a couple of amateur stations joined the table and I was optimistic that the table would improve. I was in for $1250.
UTG+1 is a fairly ok winning player, who often likes to play a little bit of a LAG style pre flop and is capable of raising and 3 betting light in position. I noticed in this session he had been less active than normal and we hadn't tangled in an significant pots. I have a fair bit of history with him and he respects my game and in the previous session asked my opinion on the way he played a hand and what range I was putting his opponent on.
UTG folds UTG+1 opens to 25
This raise was pretty standard for the table and a standard open for this player.
I would assign a range 77+ all suited Broadway's, AKo, AQo and maybe KQo & AJo sometimes depending on table dynamics.
The 2 new stationary players call , one from MP and the other from the Button.
The pot is (5+5+25+25+25) 85 and I look down at KsKd and 3 bet.
The effective stacks with UTG+1 is ~850 who has me covered and the other two have around 550-600 each.
I raise to ...........( from the SB) (starting stack 850)
Your sizing, your reasoning and you post flop plan and I'll then post what I did and why.
