V is a house player who plays limit on the casino's dime, but uses his own $ for no-limit. I've played with him a few times before. Seems to stick to a mostly ABC strat value strat, but we've never played together for more than 1 hr in a single session over maybe 3 or 4 sessions. This happens about 30 min into a new session and this is already my 3rd pf 3bet.
V opens $20 from CO. Hero goes $105 from sb with 9♦ 9♥ and we're heads up to the flop.
Hero $115, V goes all in for $520 total. Hero?
