i would like to know what these two players might be thinking when a hand like this gets played, what might some reasonable ranges be?

its a 4bet pot and they are 250bb deep. i dont think Denoking would usually be strong here as bbvis 4bet range {QQ+ or JJ+/TT+? AKs AQs? Axx SCs} this deep would be more polarised (i presume) so he may want to take a check/call line with his pair hands?

as played we do see bbvis 4betting 99 preflop in position for value, would this be the top of his pocket pair range? and denoking calls with less than Tx which is what i felt in the first place that his leading range was not a made pair on the flop, unless he decided to lead exactly 8x then call river
