[Perestroika]

The other information I need is something like...this type of player doesn't fold the second nuts/or he is very prone to folding here. Stating that they are "solid tags" does nothing to clarify the situation for someone trying to answer your question in a bubble. I think the play is fine in a vacuum against your "solid tag". But notice here the problem. Does that mean him being solid include reading you well, or possessing a complex understanding of the game, or does it mean he plays straightforward and your 4 bet means he is going to fold? This is something ONLY YOU AND THE OTHER PLAYERS IN THE GAME CAN ANSWER. Hence your question is unaswerable IMO.
