So much awful in the above post and the bottom line is still MUBS.
Anyhow...
MP2 $190
MP $1200
Hero $650
$28 is from blinds + straddle + one limper.
MP calls $10 then calls $50 with total of $50 added to the pot.
MP2 calls $10 then shoves $180 more, total of $190 added to the pot.
Hero raised to $50 initially and has $50 invested in the pot.
$28 + $50 + $190 + $50 = $318.
$318 and $140 to call for hero and MP.
If hero shoves the remaining $600, that would make the pot $918 and $600 for MP to call.
918:600 or 1.53:1 - making ONLY a coin-flop like AK a mathematical call. $600 is also a really big bet in most 2/5, and without stating that this isn't a crazy game, $600 is not going to be called by someone that isn't on tilt or someone that is ahead of QQ. If MP had AK, he's not shoving it in after he had call $10 then call $50.
It is also very unlikely that he has AK given the action, unless this guy was labeled super tight passive.
So let's be honest here, shoving here only has one intention, which is to get a fold.
I would much rather raise something to create a side pot, but with the awkward stack sizes created by MP2's shove, I am better off simply shoving as oppose to making it a very weird situation for me on the flop.
So let's just look at flatting. If we flat here, the pot becomes $458 with $140 to call for MP.
$458 pot and hero has $460 behind - I'll round it up to $460 pot to make things little easier for calculation.
So 460:140 or 3.3:1 with 920:140 or 6.57:1 as maximum implied odds.
Assuming MP has made up his mind to continue post-flop only if he flops something good, let's create a range for MP.
Given that he had two chances to raise the straddle and only called both times, I am going to eliminate TT+, AQs+, and AQo+ from his range. Just doesn't seem to make sense without relevant reads to support it.
I know how much villains at this level like suited Ace, so I am adding A2s+ - AJs. I am also adding ATo and AJo. Less I think is folding to the $50 raise. Then I am adding all of the suited broadway cards, because again, typical villains love suited big cards. Adding all PP from 22 - 99, and lastly, I am adding 65s up to KQs.
Using PkrCruncher, I also added the 3rd player with blank cards and the calculation that only deal to flop.
Hero with Q
Q
: 78.7% or 3.7:1F
MP (22 - 99, ATo, AJo, 65s - KQs, QTs, KTs, KJs, A2s - AJs): 13% or 6.71:1 dog.
MP2 (blank cards): 8.29% or 11.1:1 dog.
There's a lot of room to tweak MP's range, but according to this calculation, he would literally have to hit something dead on and also have us shovel all of our money in on the flop to make his $140 call close to neutral EV.
Furthermore, using PkrCruncher, I will break down the odds of villain flopping different kinds of hands.
1 pair - 1.03:1 Favorite
2 pairs - 11.4:1
3 of kind - 20.1:1
Everything else is above 200:1.
Draw hands
4 to flush - 13.5:1
Gut-shot - 12.3:1
Everything else is above 40:1
You have to also realize that our perceived range is very strong, and it does indeed include AK and AA, so hitting an A or K on the board does not automatically mean stacking off for villain either. In other words, we are once again suffering from MUBS if we think any board with A or K is atomically bad.
So all in all, I am flatting all day here.
