yes when you go down to 2 people, the blinds go back and forth. (when down to 2 people, blinds
don't really make that much of a difference compared to ante). However with 5+ people, blinds make a big difference
assuming the people playing are not newbs.
A better way to illustrate my point above is with an example.
lets say 5 people are playing.
1 2 3 4 5
Who acts first rotates around. Lets say for this round, player 1 acts first. If player 1 knew what he was doing,
he would have to play very tight because all of the other players play behind him. Also, if he does happen to have something good
to play like kk, ak, aa, and he puts in a bet, it immediately alerts the other players to his strength due to his willingness to play even in such
an early position, thus likely minimizing his gains. In an ante only game, the first to act would almost always fold except when he holds very strong pocket cards
but when he doesn't fold, it alerts others immediately to the strength of his hand.
Thus, this illustrates the importance of position. But in a blind system, player 1 lets say pays the big blind, player 5 pays small blind.
Now, these 2 players are already partially commited or commited to the pot and the other plays have problems differentiating between whether they are
just defending the blinds or really have strong hands.
