I have no read on any opponent, because i play Nl500 atm. I posted this one before in SSNL, butthe oppinions were very splitted. I think this is a clear 4bet, right?

[Darkfolder]

Yeah, easy 4-bet.

I'd 4-bet this all day, but if Chippy1 decides to come along again, I probably wouldn't put in more money until I hit something.

[Evigt_Drabbad]

yes 4-bet!

Vhippy folds and Fra moved AI. I have to call, right?

How much was your 4bet?

Regardless, yes you do.

4bet a little bigger than pot size, committing urself to call a shove if someone were to make it, while hopefully folding out any pairs below TT. Jus try to isolate Tomcat.
