I’ve been doing a lot of hand analysis, but today I was thinking about analysis of an entire session.
Today, to gather some sample data, I played a 4-seat table for 100 hands, and plugged the pot sizes into a spreadsheet and ran some basic stats on them, and came up with these numbers:
|Hands with losses*||50|
|*includes preflop BB and SB folds|
|Total Chips won||58855||147.14|
|Total Chips Lost||-36000||-90.00|
|Total Chips Net||22855||57.14|
|Average Pot Size||2850||7.13|
I probably won’t attempt to run this sort of analysis very often, unless I’m very interested in the session, due to the time it takes, but I thought it was interesting and potentially worthwhile to see what I can do with the numbers I can obtain from the site without a huge effort.
During the session, I felt like the table was fairly weak/passive, players over-folded or else were all running very cold, it was hard to build much of a pot, and I hit top pair a lot, pretty much any time I had an Ace or King in my hand, I flopped top pair with it. I also hit my draws a good proportion of the time.
I felt like I was the only player at the table who felt comfortable opening, but due to the weakness at the table, I wasn’t able to open very large, and when other players opened it was very occasionally and never for more than 2BB, while my average opening size was generally 2.5-3BB.
Consequently the average pot size was quite small, but I won most of the large pots, and I lost very few hands at showdown where I was betting, I think only 2 or 3 out of the whole session. I did not try to bluff in any spots.
Looking at these numbers, it seems I could have perhaps done better with bigger openings, and sacrificed some early hands as blind steals until the table decided that they needed to call larger openings if they were going to see any flops. This would have driven up the bet sizing at each street and resulted in bigger pots won, and possibly I could have also won a few more hands through blind steals that I opened but ended up not winning.
What other numbers would be useful to know? What lessons might I infer from such analysis?
Note: Looking at the sum of count of hands won and hands lost, at first it looks like I’m playing a very loose 80% of hands. This is misleading, because hands where I folded the SB or BB preflop, or was allowed to limp the BB and folded it postflop without voluntarily committing more chips to the pot also count for “losses” due to the way I wrote the function used to label wins and losses. So this could stand to be improved, but in order to clean up the data more, I’d need to put more time into the data entry, and it’s too time consuming to be worth the effort to do that. In actuality, I probably opened about 40% of hands, and played a further 20-25 hands from the BB when I was allowed to check to see a flop, and limped the remaining hands.
