Personally, I think that NL cash games should be a set blind say 50/100 and that 100 is still a minimum bet on 4th and 5th street (why someone would make such a play I don't know, but anyway) - I have a couple of guys who run home games like that too. The minimum bet is 100 on all streetsI've seen this done both ways. the minimum bet does not change from preflop/postflop to the turn/river. The small blind is 50 and the large blind 100. so even in a 50/100 NL game the minimum bet would be 50 pre and post flop and 100 after the turn and river.For NL the 50/100NL are the blinds.
the stakes just mean the mimimum bet for a betting round.
