This is a rare treat because I feel that for once I understand something that some people posting in this forum may not get. There's a difference between the range we put people on, and the possible hands they can have in a situation.
Example 1: Lets say we sit down at a table with a solid regular we know well (assume we don't defent SB much). He is on our right and in BU and we are in the SB with an unknown in the BB. When you post a hand, players in this forum will ask you to put him on a street by street range, but sometimes this range will be very inaccurate. If the BB is a a 4/2 nit he may be opening 100% of hands. If BB is extremely aggresive, he may be opening a much tighter range.
That villain could be playing 27o or not, we don't know. Sometimes we adjust the ranges we put people on based on the idea that it isn't clear what hands someone has.
Example 2: Now lets say a guy who so far looks like a regular calls a 3bet IP against us BU v BB. We know it would be a leak for him to call our 3bet with 22-88 since we are 100 deep and he doesn't have enough implied odds, but alot of regs have this leak. In evaluating his preflop range we might weight his range by giving him 66-88, and not giving him 22-55 in his range. This statement does not mean he will call 66-88 and fold 22-55. It means he will call 3/7 of the time with 22-88. If the flop comes out 2JK, we can continue to keep his range weighted by putting 3/7 of the combos of trip 2s in his range so maybe we put 1 combo of trip 2's in his range instead of 3.
This is not exact, and it really cannot be as we just pulled the number 3/7 out of our ass. This kind of work is often done to make our math more accurate, but often you can get away with just plugging all of the combos of a hand in cause meh, its close enough. However this is not always the case. Consider this next example.
Example 3: A fishy villain who we have observed calls bets with air often calls our 3bb open bvb. We put him on a very wide range preflop. Flop comes Qd8s8cWe bet the flop, and he calls. At this point we know his range has tons and tons of air as well as queens trips pps and air in it. The turn comes a 2h and we check. The pot is now $2.75 and our villain bets his last $2.25 and we are trying to evaluate a call. Do we think he will play 67s this way? Probably not. In fact, he probably will not play most of his air this way a high % of the time. For simplicity lets assume his range is just air and value. The thing is if for the purpose of this conversation we say 4/5 of his flop calling range is air and he plays his air this way on the turn 1/8 of the time and he plays his value this way 100% of the time 1/3 of his range is still air. This can have a huge impact in evaluating our call in this spot.
Ie. this stuff can matter.
Hope this helps some people as normally its just everyone teaching me stuff.
