Flop Analysis
Checking back our bottom pair is the standard play to control the pot and realize our equity.
While we improved to trips on the river, shoving for nearly 6x the pot is a massive over-polarization that loses value from the hands we want to target.
Checking back our bottom pair is the standard play to control the pot and realize our equity.
Checking is correct here as the Jack is a better card for the SB's range, and our bottom pair still functions best as a check-back to realize our gutshot and pair equity.
Betting for value is mandatory after trips land, but the 37BB shove into a 6.5BB pot is a significant strategic error. We want to be called by Kx, Jx, and 8x, which all fold to this massive sizing.
Note: The massive overbet shove (570% pot) is far too large; it forces Villain to fold almost everything we beat and only call with straights or better trips.
