Just want to talk about shove ranges.
When out stack gets small enough to start playing shove/fold pre, there are three times when we shove. The first two are easy.
1 ~ If we have a prime hand. We shove this in from any seat at the table.
2 ~ If we have very short stack, say 5bb or lower, we shove pretty much anything. We’re basically playing our suckout value.
The third situation is what separates good ICM players from meh ones.
3 ~ If we have a decent hand (good but less than prime) we shove if the table is weak and fold if the table is strong or even semi-strong.
This is where the card players judge their cards as good enough and dismiss all of the other factors. So how do we know if the table is weak or strong? By the betting. If there are one or two limpers and a bunch of folds, the table is weak. If someone opens, the table is strong. If someone opens and gets called the table is very strong. If there are 3 or 4 or 5 limpers, the table is semi-strong and we fold.
Of course this means that we cannot judge the table strength unless we see the action first. Which also means that we only consider jamming our decent hands from the BLINDS! ; ) Our prime hands shove from any position but our decent hands only from the blinds when the table is weak.
Why? Because our prime hands are for doubling up. QQ? We want calls! But our decent hands, we are STEALING! A3s, 44, etc, we want FOLDS - or a call from a limper (because a limper has a wider range that our decent hand can compete with).
Consider the hand above where the SB jammed A-rag over two short-stack all-ins. We see our position, the SB. This is a good position to jam from because we see all of the action (except the BB, so the 2nd best seat to jam from). We have a decent hand. A-rag wins many hands all-in pre when no one hits the board. However, it’s not prime because it has a weak kicker. So if the table is weak we will shove it in the BB’s face.
But what happened here? MP shoved 9bb. Now, even 100bb deep 9bb is a VERY large pre-flop opening. So MP is strong. In fact, since we know that the blinds are the best shoving positions, MP has a tighter shove range. He has to be more certain to beat all the hands calling behind, he has no info on. We get the info from the blinds, we see the betting. MP doesn’t, so he needs the stronger hand. This is NOT GOOD for our A-rag. Furthermore, the BT calls all-in with 8bb. The BT is confident that he can survive showdown against a strong MP!! The table here is VERY VERY STRONG! Our A-rag on SB should gth outta here!
See?
Now if he shift to the BB on 88 here. We must assume that the SB is super super extra strong to jam over a very very strong table. That’s why I say that the BB with 88 is a good fold.
