Mike, Just in terms of an average, I'd say about $400 per session. But that was really variable throughout the sessions in that log. It isn't uncommon for me to buy-in on the installment plan. So I may start out with $200 and add another $200 or $300 later on. I try not to play more on a session than I had intended; but I don't always buy all I intend to play right off the bat.
I just fiond sometimes that it is easier for me to manage my money at the table if I don't start with a huge stack. And I understand that the pits like to see guys reaching in for more, and don't like seeing guys buying in for $500 and then betting nickles to start.
Sometimes, however, I may go the other way. Depending on how long I am laying, whether I know the place, the overall atmosphere, etc, I may decide to buy-in for $500 to $800 right off the bat. The biggest buy-in I ever did was $1000; but I don't think I ever did less than $100 either.
At almost all of those cruise ship sessions, the bankroll was $100 for the session; and I was, in the beginning, risking my trip bankroll in its entirety with each session. We (read: "My Wife") had decided we (read: "I") wouldn't play on this trip at all; but at the last minute before dropping us at the pier, her Father gave us each $100 to gamble on the trip. So my wife agreed that we could each gamble that, and only that. So I started with that $100, buying all of it in chips to start each session and cashing out each time I left the casino. That $100 grew to as much as $800 at one point; but I would still buy-in for $100 each time I started play. A couple of times I would re-buy though, once I got up a little.
The recent trip to Mohegan Sun was with an $800 bankroll. I bought in for $300, won a couple of hundred, cashed in my original $300 while on a restroom break, played on with the $200 in winnings, and at one point, re-bought the original $300 when I needed it to split aces with a big bet on the table. So you can say that I had a session bankroll for that win that was $300.
That is what I like to do: start with less than I am willing to play, get up early, and continue to play on the winnings. All of my wins at Sam's Town ($4500, $600, and $650) came on $300 session bankrolls that just went up from the beginning.
On the other side, I find it more difficult to lose all I have if I have to reach into the pocket multiple times than I do if it is all converted to chips in front of me. The biggest losing sessions I've had ($1000 and $600 at Sam's Town, $400 in New Orleans, and the $300 on the ship) were all cases where I basically wagered everything in front of me right down to the napkin my drink was sitting on.
I have a seperate "Casino Wallet" that I take with me on trips where I'll be gambling. It has pockets for all of my Players' Club cards, which is where they all stay between trips. I normally either keep my full trip bankroll in that wallet; and all transactions to buy-in or cash out are done with that wallet only, not my "regular" wallet. If the trip is a long one, I'll carry my daily bankroll in the casino wallet and leave the rest of the trip bankroll in my room safe. Either way, I try to keep my gambling money seperate from my "regular" money. That helps me in accounting for wins and losses each day and on the trip as a whole.
I don't normally play a lot of short sessions. I don't do a lot of table hopping. So it is fairly easy for me to keep up with each table I play, as far as wins and losses. During the game I will stack my red chips in stacks of ten ($50) and I change up my green stacking depending on how many I have. I normally stack them in tens as well ($250); but if it starts to spread out too much, I'll go to 12s. Usually by that point, I have a small stack of reds anyway, so I stack them in 12s too. THis makes it pretty easy for me to always know where I stand up to the minute. A glance down shows me if I am up $200 or down $50, etc.
I have recently started pocketing some of my chips if I get up in the game. I will especially do that if I have black or pink. More than anything else, I do it for security. S single pink chip is much easier for a sneak-thief to swipe than would be two stacks of green. So even if I'm "playing" with $1500, you may only see $500 in front of me at a given point.
I know I took the long way around to answer you. But I do change up quite a bit to suit the circumstances. I am a lot more consistant now, snce I have an established long-term bankroll that dictates trip bankrolls, daily bankrolls, and session bankrolls. When that log started, I would just fly by the seat of my pants, playing whatever I had whenever I got the chance. Now I am more comfortable saying that I like to buy-in for $300. But as an average over that log, I'd say it was about $400.
