I searched a bunch, and found some information, but none of which was explicitly clear about live play.

Regarding the formula or raising a pot pre-flop for a limped pot, when I see recommendations for 4x+1, does that means 4 times the big blind plus one big blind per person?

For example, if 5 people limp in front of me in 1/2 and I want to raise, that would be (4 multiplied by 2) + (5 multiplied by 2) for a total of $18.

Is that correct? Is that how it is normally written in the forum?

If so, are 4x+1 or 5x+1 the standard recommendations for live 1/2 casino play?

Thanks in advance.

There's no standard amount. In general, people raise bigger pf in 1/2 live than in bigger games live or on-line.

Where I've played, a 5BB or 6BB opening raise is treated like a 3BB raise everywhere else. If you are looking to get people to fold after a limp, you need to raise 9BB at a minimum.

Its very game dependant. Ive been in games where 8 dollars is a normal raise but most 1/2 games standard raise is 12-17.

Raise exactly 4.2357 times the BB everytime. The dealer usually has quarters in his pocket so you can make change to the exact amount.

Seriously, it depends. Unlike the somewhat homogeneous blend of players online, every live table is different.

Some tables a $20 UTG preflop raise will get 5 callers. And $15 to $25 raises are "normal". In the same room, with a different group of players, a $5 raise will fold everyone around to the blinds.

You will have to observe what others at the table tend to raise and note the results. When you raise, see who has a tendency to call and who autofolds.
Experiment with your raise amounts, and observe the different raise amounts of others, and note the different results.

Why are you raising? Because you have XY suited, and you are "suppose" to raise 3x+1.25 per limper? How about you are raising to isolate, or maybe you are raising to steal blinds, or are you raising for value? This reasons will dictate different amounts.

AND IT IS A LIVE GAME. If a guy yet to act is jumping up and down in his seat and grabbing for his chips, maybe you don't want to raise at all, maybe you want to limp and re-reraise (and the reraise should be exactly 3.8879x the original raise ).

very table dependent

my standard when I first sit down is 5x+1 per caller (in bbs). However, if table is super tight, I drop it down to 4x+1. If table is super loose/if there are loose passive fish I may even announce my hand by raising 9x or 10x (or whatever I think I can get away with) with premiums, since the fish will just continue to call.

Also 3-bet for value almost exclusively (but you can widen it beyond the nitty live standard of AA,KK,AK). Don't polarize your 3-bet range. If someone raises, he's almost never folding to a 3-bet unless its massive.

yea 3-betting light live verse anyone but very competent players is no good. You will get called as long as youve played some hands.

6x+ is standard at my casino, and alot of people calling... last night I even saw some 15x raises usually with a call or two behind.
