best to just flat this preflop, otherwise we are
bluffing with possibly the best hand.
we need to have a basic plan laid out when we decide to do something. This guy is a tight looking player thus far, raising from UTG in a format which is pretty tight in opening raise ranges but loose in limping ranges typically. So when we decide to 3bet, we need to know exactly what we will do if he calls/4bets as that is what we leave him with when we make our decision.
By calling, and playing it very passively and somewhat weak. We get to see a flop and then decide how many chips we want to invest. Generally though, since were facing a tight UTG range, our hand strenth diminishes, so basically i treat this hand like i'm playing 88-99, so we're looking for cheap showdowns and to obviously hit our set postflop. Unless we hit our set or we have a very strong read on this player, we're never really looking to get it all in postflop.
The reason players are able to play 10-30 SNGs at a time is due to the fact that they think about decisions like this away from the table, so if you want to get deeper in this spot, think about what happens at this rough stack depth when we 3bet and he calls, think of it like a decision tree. If we flat call, his decision tree is very limited, whereas ours becomes much wider depending on action behind us. With 3betting, his decision tree narrows and our decision tree narrows also. So if i'm thinking about this spot....
If i flat call - we can get to a flop cheaply, possibly flop a set, we get to decide to put more chips in on favourable flops as his range is very capped here AQ-TT maybe AJ-AT KQ, so it will be an easy hand/flop to read postflop and we almost always know where we are in the hand.
if i 3bet - if he folds, how many chips do we pick up? is it worth the risk vs a tight range and how much does he likely fold. Lets do some quick math to work out how much
equity we make here.
if i 3bet and he flat calls - Flop will be 6-700 and we have only around 1k chips left. JJ faces overcards roughly 30-40% of the time and we are still vs his original tight range, folding out maybe the outside hands like KQ AT-AJ but they also might possibly call as players in this level are typically bad. This seems like a really akward decision tree i've left myself in and i want to avoid this as we're getting close to being pot committed and we commit ourselves on dry flops with no overs. The plus side might be that we can assume he 4bets hands like QQ+ AK so it possibly narrows his range slightly when he just calls, and it tends to be weaker, but again it's a low level, so players can still flat with those hands to trap or because he's scared.
if he 4bets- Can we call it off? what is the math needed. IT seems like we have to fold as his range narrows from above, to something like AQ+ TT+ at the absolute widest, vs that range we don't do particularly well, so we're almost always calling behind, however we are getting pot
odds here also, so lets work out if it's a profitable call spot.
After i go through decision trees like that, you also want to think about other things like how easy or hard it is to pick up chips in future hands. The easier it is the more you want to avoid these situations and make them very low variance spots. The harder it is the more willing you want to be to take on high variance plays.
Sorry for the babble, but doing this away from the tables will really help you in game, and you will be able to play more tables once you do this for a ton of differant situations in the early/mid game. Just like in the late game where we train ourselves to jam a proper amount of hands for the situation, we also want to train ourselves to be able to deal with any situation really quickly and simply.
anyways hopefully this helps.
I will have to re-read it over again and it takes a while for it all to sink in
