wouldnt you want to get money in the pot anyways in case you did hit the set or ended up with top pair? ......... probability of hitting a set on flop with any pocket pair is around 11%.....hitting quads on the flop =
App .25%.....prob. of hitting any pocket pair = app. 6%.............
therefore..... out of every 10,000
hands 600 will be pocket pairs, 67 or 68 will hit a set or fourofakind on the flop......
AA KK QQ JJ may win the pot without connecting with the flop .....1.8% chance of getting JJ or better preflop......thats around (180 pocket J's or better - 20 hands JJ or better that hit sets)..... 160 hands that could be played regardless of flop texture......
so......excusing the obvious discrepencies in my math.... if you only play pocket pairs you have around 220-230 hands per 10,000 that are playable..
10,000 hands per 6-max table = around 1670 big blinds/220 "winning" hands = .... you need to gain 7.6 times big blind on each "winning" hand to break even using this style of play...... and thats not including hands that you lose.
hmmmmmmm...... i cant say if that is realistic or not ....
