Hey guys,

I was just running some hypothetical situations in my GTO+ solver by constructing ranges from two different villains in my database and picking random cards on Flopzilla to see how ranges interact with random boards. I have a question about why one hand is almost always a call and another of similar strength is almost always a fold according to the solver.

Flop goes check check, on the Turn OOP bets 3/4 with a call from IP, the river makes the board 7h4c3d 2s 6c.

OOP's betting range on turn for 3/4 pot is 54s, 77, 99,TT, QQ, K9s, AQs, AJs. OOP calls with 55-66, 99-KK, AQs+, AQo+,

On the river when OOP bets pot with relatively the same range IP is folding JJ about 80% of the time while calling with TT almost 90% of the time. On the same token 99 is a 100% fold.


99, TT, and JJ are all overpairs with similar equities in Flopzilla. Interestingly enough TT has slightly more equity than JJ in Flopzilla. I can't figure out why. Both JJ and TT seem to block out the same amount of essential elements that create OOP's value range. Could this be simply for balance? Could it be that both PP's unblock differing combos that I didn't think of?

How do I dig deeper into the results from this solve and uncover why one overpair is almost always a call and the next overpair down is almost always a fold?

Look at oop's betting range, JJ blocks some bluffs while TT block no bluffs. 99 also blocks bluffs but doesn't beat any value which is why its a pure fold.

If villain bluffs included ATs instead of AJs then TT would fold more and JJ would call more.
