I am in middle position in a $1.00 $2.00 no limit game and the average player has $200.00, It went fold fold fold, my turn to act, bet pot, $7.00, call the $2.00 or bet more than pot?????
Raise to $7-8 to weed out the weaker hands.
The problem with not raising with any large PP in MP is you let too many weak hands in, including the blinds.
eg: Say you limp in and there are 2 more limpers behind you and BB checks, flop comes 462 rainbow, SB and BB check, action is to you and you will obv put a bet in and 2 folds and BB just calls, turn card is a 10(another good cards for you), this time BB bets, you're not scared of the 10 so you come over the top of BB and he calls again, now depending on the size of your reraise, you may be able to put him on something like an overpair to the board or even A-10 at this point, the river comes J, now you have a hand which beats any overpair villian may have or any trips he may have , so BB again checks, you put in a nice pot sized bet at this point and villian comes over the top of your bet by pushing his remaining stack in and you call thinking you have him beat.
Villian turns over 35os and now you're kicking yourself for not raising preflop which would have chased the BB out of the pot.
If you constantly limp in with PPs you suffer from FPS(fancy play syndrome) and that will kill your BR more often than not.
