The villain is the same in all hands. He is an aggressive TAG. He has been CRing the flop a lot. He seems to not have a pre flop 3 bet range. I haven't play a lot with him but he seems to be solid.

Are any of these spots to check back the flop?

Hand 1) I open the button with QsTd and he calls in the BB. He checks

Hand 2) I open in the LJ with 6s6d and he calls in BB. He checks

Hand 3) I open on button with KK's and he calls in BB. He checks

AhQc3d

1) no, 2) no 3) absolutely

The type of hand that wants to check back is usually 1) a weak-marginal hand that can lose a lot of its strength on the turn or 2) borderline trash that is strong enough to want to see another card, but too weak to handle a check-raise

The type of board that we want to check back is one that mostly removes our range advantage. The most common of these board types is a middle card board with 2 to a suit.

Hand 1: This board heavily favors our range and our hand is fairly strong. It is not very vulnerable to bad turn cards. I just bet.

Hand 2: This board hurts our pre-flop range advantage a bit, but not too badly since we raised in the LJ and will be much heavier in pocket pairs than we would from the button. Plus 66 is a fairly strong hand. I also bet.

Hand 3: This is the same situation as hand #1 except that we are now more likely to get value check-raised by worse hands. This is even more of a bet for me than hand #1. I want to be check-raised by someone who is check-raising excessively.

Interesting. I could see checking back all 3 hands

I would just bet. I’d rather check back on more connected boards than those. As is, there’s a lot of value. I wonder what his turn raise strategy looks like if he is check raising flop a lot. Some people always delay raise with strong hands, so their flop check raising range is weaker and their turn check raising range is insanely strong.

In hand 1, we have 2nd pair/weak kicker on a rainbow board and our ten is blocking some villain's gut shot straight draws. I see nothing wrong with checking back and inducing our opponent to barrel off his bluffs while saving 2 small bets when we're beat and get c/r'd

Hand 2 is similar imo. Yes we have a vulnerable hand and can easily stand getting c/r'd, this flop should still hit more of bb's range than ours. Plus, we can pick off bluffs and are more likely to get in a raise when we catch perfect. We may also get a lot of free show downs on runouts that might prevent bb from barreling

Hand 3 I don't see a huge problem letting a free turn card fall and inducing bets from worse hands on turn and river. Betting gets at least called by better hands while forcing out many more hands we don't want to fold

But it's always player dependent. If villain is the type to always chase gut shots and call down ace-high. then betting flop easily could be the most profitable line to take in each of these hands

Lastly, (as I think unguarded mentioned in another post), by including "some" stronger check backs in our range on flops and turns, allows us to arrive at a more optimal bluff to value bet ratio even on blank turns and rivers

Idk how it could be good to check back with so many hands on these boards. The second board I could see checking back with some hands, just not with that holding.

I don't have check back range on board 1/3. I do on board 2 but not with 66.

Hands 1/3 he has some strong hands but he also has a ton of weak hands and a ton of absolute garbage. If he is checkraising super wide then calling down with second pair should be easy game against that range. Let him make his biggest mistake by barreling off super wide. Checking back with 2nd pair is leaving money on the table.

I open in the CO and only get called by the BB. He is very laggy but good. He is very showdown bound on non uber scary boards. He CR's a good bit on flops with any pair on a board like this and numerous draws. He's not folding Ace high unless it gets really ugly. He is stubborn with K high and Q high hands. He flats his whole range HU here pre.

I have Ad7d

9d8c3s...On one hand I can get two streets of value from his K and Q high hands. I get value those times he CR bluffs and he whiffs. I value own myself often as well against better Ace high's and will get value CR'd a good bit. I don't like that there is no turn card I will want to raise on. I would just call down a turned st or flush draw. I think I would let him continue to bluff if an Ace hits.

This example is a good check back candidate. The rainbow board makes it slightly less desirable than a 2-tone board, but otherwise it looks great. Getting check-raised on this flop with this hand by an aggressive check-raiser does indeed suck. We would be in that gross place where we have just barely enough hand to call down and want to puke on the big streets.
