NL20 SH top two pairs against reg

[iceTray]

So here's the line.The enemy is a solid reg with 21/15 and agressions of 30/19/23. What is your opinion to b/f here. Can his raise be a bluf in sufficient times to shove would be +EV?

Why did you fold top two pairs on this board? I think thats the worst you could do here. Villain's range is full of pair+draw type of hands, but he could possible had AJ or straight draw+flush draw type of hands as well...

i dont think he would here bluff in a 4way pot. with a strong flopped flush he wouldnt raise.
so value hands he plays this way are:

1, we beat: min. 6 max 18 combinations(6 combos contain a diamond)
-A4 2pair(6 combos but if suited: just 2 combos---i dont consider he would call pre with A4o)
-Ax type hands with a fd.: AQ(8 combos, but with the Qd they are just 2 combos), AJ(8 combos, but with the Jd they are just 2 combo) agaist combos containing a diamond we have 55% eq. if he hasnt diamond this is 84%.(this is 12 combos)

2, we are beaten by: 11 combos
-combos of sets are 3 combos of 4's + 1 combo of tens. (since likely he raised with AA pre)=4 combos
-possible cards he made flopflush with: 23(maybe),56,67,78,89, q9,j9=7 combos. if he had qj i think he would just call, and kq is the same. here we have ~18%eq

3, we tie
-AT (4 combos)

(6x55+12x84+11x18+4x50)/number of combos=(330+1008+198+200)/33=52%
plus maybe we have some percentage of folding eq too but not too much. so push seems to be a bit better here but the two decisions are very close.
