One of the largest leaks in my game is when I open with a decent pair (1010 or better) and the flop comes 3 under cards with 2 being suited. Its common today for folks to call opening raises with lower suited connectors and gappers. These flops allow for all kinds of opportunity with straights and flush draws plus they also can hit 2 pair or the dreaded set. So I make the cbet 2/3 pot trying to get value for the over pair and defend vs the drawing hands. Often at this time the villain will re-raise the looking to get both streets of the draw for cheap. Once I know their image and feel fairly good the pair is ahead I 4 bet to make them pay. Maybe this is the error but anyway often the chips get all in and they hit the draw. I go busto. So any suggestions how to defend the overpair to a flop of undercards containing 2 of a suit?
General Statement
It's important to lay off the gas pedal when boards become wet. All the money put in preflop and on the flop is wasted when a third suit comes on the turn or the board pairs.
On the flip side, you must keep pressure on the opponents and force them to pay for the draw.
It takes practice to keep the pot small while still getting appropriate value for the hand. Keep in mind all of this is relative and this type of situation could have a unique set of circumstances that could change the decision in question.
"Remember the Nuts"
Don't forget to keep your relative hand strength in mind in these situations on later streets. I've seen players call on rivers with four of a suit on board just because they fell in love with the hand preflop. Know when to release a hand, if it's not worth it. Just another reason to keep the pot small on earlier streets, it makes the bad river "position" easier to fold.
"Raise Sizing"
Analyze the preflop raise sizing in your game. You may find that increasing the preflop raise slightly can have a big impact on the flow of the game for you and help reduce the amount of callers in general. Don't go overboard, but reducing the players in the hand is usually a good thing. (3.5x-4x)
"10 10 or Better"
There's a big difference between a pair of tens and pocket aces. Obviously each situation is unique but don't undervalue the larger pocket pairs as one of the very best situations to be in is "set over set" situations with larger pairs.
"Find Your Groove"
A good piece of advice is to constantly try to find the best version of your game by making small improvements and analyzing the results. Don't be afraid to try new things. I have found out interesting things simply by attempting new styles of play in different situations. Don't get stuck in a rut, find your groove.
